1775 FLEX PLANTER

MaxEmerge 5 with 56-L (1.6-bu) hopper plus insecticide

MaxEmerge 5 with mini-hopper on Central Commodity System (CCS™) machines only

The MaxEmerge family of row-units have never seen a more versatile and efficient design until the MaxEmerge 5. The 5-family row-units improve productivity, increase uptime and lower the cost of ownership like never before.

The MaxEmerge 5 row-unit was designed for improved performance and serviceability.

Serviceability and changing crops has always been a focus of downtime and potential seed loss. MaxEmerge XP row-units (shown on the left) are designed with the meter and hopper as one component. The frame covers the meter so that it cannot be accessed. Cleanout of excess seed requires the operator to take the entire hopper off of the row-unit and to turn it upside down. The MaxEmerge 5 meter (shown on the right) is accessible without having to remove the box. The MaxEmerge 5 design allows large hoppers to be cleaned out the same as mini-hoppers, simply by opening the meter dome and catching the seed as it falls out. This improvement allows operators to change seed varieties easier and three times faster than it took them on the previous MaxEmerge XP units and provides more uptime during the tight planting window.

MaxEmerge 5 vacuum seed meter

The vacuum meter system gently pulls and holds individual seeds to the holes of the seed disk for population control and spacing accuracy, equaling better crop stands and profit. Vacuum seed meters can plant a wide variety of crops and seed types by simply changing seed disks and adjusting vacuum level. Vacuum seed meters are available for planters with MaxEmerge 5 row-units.

Additional features of the vacuum seed meter include:

• One moving component (the seed metering disk) for minimum maintenance requirements
• Meter located at each row-unit for accurate seed delivery
• Good hopper seed flow characteristics for longer operating time per hopper fill
• Low airflow in meter so seed treatments are not removed

Pro-Series™ row-unit seed pool

MaxEmerge 5 seed pool

The MaxEmerge 5 meter shape has also been redesigned for better seed flow. The mini-hopper design allows the planter to successfully operate on side hills up to 14 degrees.

Vacuum meter hub and latching handle

MaxEmerge 5 vacuum meter with disk

Both the MaxEmerge 5 vacuum meters are equipped with a heavy-duty hub spring and disk latching handle. The spring ensures the seed disk stays properly positioned when operating flat-style seed disks and higher vacuum levels. Proper seed disk positioning means repeatable seed singulation, time after time. The disk-latching handle is designed for easy operation and effortless seed disk changeover. The hub is also machined to tight tolerances to further ensure alignment of metering components.

Flat-style and cell seed disks shown

The unique cell disk design allows planting a variety of seed sizes without any additional parts or individual meter adjustments. Another advantage of cell-type seed disks is the lower vacuum requirement compared to flat-style seed disks. Lower vacuum levels mean less hydraulic demand from the tractor. Most planting conditions call for a flat disk, if you are limited in hydraulic capacity, cell disks are recommended.  

Operating characteristics of vacuum seed meter

Operating speed with seed tube technology

The vacuum seed meter is capable of operating at faster planting speeds than mechanical meters. However, planting accuracy will be influenced by seedbed conditions and the operating characteristics of the seed meter. Rough seedbeds and fast planting speeds (above 8.9 km/h [5.5 mph]) typically deteriorate seed placement accuracies when using seed tube technology.

The chart illustrates the effect operating speed has on population when using the vacuum meter. The operating band (color area) illustrates how the vacuum meter performs in relation to the desired population (indicated by horizontal line). The width of the band is due to various sizes and shapes of seeds and planting rate variations.

When operating on slopes above 15 degrees, increased or decreased population may result. To minimize this effect, reduce speed and consider using a flat style seed disk with increased vacuum level.

Vacuum meter seed disks

The ProMax 40 Flat Disk is a flat-disk planting solution field-proven to work since 1991.

The design of the ProMax 40 Flat Disk position allows seed to be released from the optimum position above the seed tube. The flush-face seed tube allows the seed to drop uninterrupted through the tube.

The ProMax 40 Flat Disk utilizes flat holes and a higher vacuum level to ensure every hole is populated with a seed. A double eliminator gently removes multiple seeds at each hole for precise population control. A knockout wheel makes certain that each hole is clear of any debris after the seed is released from the disk.

Double eliminator

For difficult to singulate seeds, a flat seed disk and double eliminator is a viable alternative to traditional cell-type seed disks. By design, a flat seed disk requires higher levels of vacuum than a cell-type disk because there is no pocket or cell to hold the seed. The higher vacuum level will pull more than one seed to the holes in the seed disk. The double eliminator is set to cover a portion of the hole in the seed disk and is the mechanism to knock multiple seeds away as the disk rotates.

Double eliminators are required with flat-type seed disks only and should not be used with cell-type seed disks. The knockout wheel is also recommended in conjunction with the double eliminator and flat seed disk to ensure seed is ejected from the disk.

Flat and celled type seed metering disks are available to allow planting a wide variety of seed types.

• Corn (field, popcorn, or sweet corn)
• Soybeans
• Cotton
• Sorghum
• Sugar beets
• Sunflowers
• Edible beans/peas
• Peanuts
• Melons, squash, cucumbers

Mini-hopper row-units, which are used only with the CCS, are compatible only with crops that the CCS is approved to plant.

• Corn
• Popcorn
• Sweet corn
• Soybeans
• Sunflowers
• Sorghum
• Cotton

NOTE: Due to small seed size and low planting populations, sugar beets can be planted with mini-hopper style meters by adding hopper extensions and not using the CCS tank. These hopper extensions can also be used for planting test plots.
 

Hopper shutoff

Also, to help with meter access of 56-L and 106-L (1.6-bu and 3-bu) hoppers the hopper shutoff feature was added. With the shutoff engaged, the meter cover can be opened without first having to remove all of the seeds from the hopper. Lever down, the seed flow is on, lever horizontal and the seed flow is off.

MaxEmerge 5 mini-hopper

There are significant changes to the MaxEmerge 5 mini-hopper. One update is the straight feed from the CCS hose to the mini-hopper to ensure a continuous free flow of seeds. This design change reduces the potential for plugging issues with larger seed size and the use of seed treatments. By drawing air from the CCS tank, the vacuum source is cleaner, preventing meter debris buildup.

Ductile iron-cast shank

Ductile iron casting is a unique high-tech process that produces a single-piece row-unit shank this enables alignment from the seed trench to the closing wheel.

The row-unit head is also designed using the ductile iron-casting process. The row-unit head provides the mating joints between the row-unit parallel arms and the row-unit shank. It is also the upper attaching point for the seed meter and seed hopper.

Ductile iron casting of the row-unit shank and head assembly provides a row-unit that is 25 percent stronger than other competitive welded row-units.

Rubber tire closing system

Cast wheel closing system

Rubber tire closing systems are used for most conventional, minimum-till, and no-till planting conditions. The spacing between the wheels is adjustable so the closing system can meet the needs of those who want to plant small seeds at shallow depths.

The wheels can also be staggered fore and aft to enhance residue flow. Four levels of spring force are available and are easily set with the integrated T-handle adjustment. A lower force spring can be obtained from parts, if a lower amount of force is required.

Additional closing wheel options include:

• Cast closing wheels, for tough-to-close conditions
• Disk closing, for shallow planting depths
• Closing wheel frame less wheels, for growers desiring to use aftermarket closing wheels

One of the trademark capabilities of John Deere planters has always been the ability of the Tru-Vee openers to provide an ideal seed furrow.

The thickness of the Tru-Vee opener blade is 3.5 mm (0.14 in.) this blade thickness will provide extended wear life.

The MaxEmerge 5 row-unit also provides better Tru-Vee opener bearings for longer life. The double-row ball bearing provides up to three times the wear life as the single-row bearing.

Depth adjustment T-handle

John Deere planters provide consistent seed depth control in all field conditions. Depth control is a function of the Tru-Vee openers, the downforce system, and the gauge wheel assembly.

The gauge wheel itself is made of durable nylon composition with a concave profile. This profile gently firms the sides of the seed furrow, ensuring a well-defined trench. The shape reduces rocks and residue being picked up and thrown onto the drive chains and row-units, and helps to prevent rooster tailing of soil.

The bolt-through design utilizes an open bearing in the gauge wheel that allows an attaching bolt to pass through the wheel to the threaded hole in the gauge wheel arm. This simple bolt-through design provides for a positive attachment of the gauge wheel to the gauge wheel arm and allows quick removal of the gauge wheel for service.

Adjustability of the row-unit is critical to good performance. More available downforce options than any row unit in the industry

• Adjustable heavy-duty downforce, four settings, 0 kg (0 lb), 57 kg (125 lb), 113 kg (250 lb), and 181 kg (400 lb) of downforce
• Pneumatic downforce, infinitely variable from 0 to 181 kg (0 to 400 lb) of downforce
• Active pneumatic downforce adjusts automatically for changing ground conditions from 0 to 181 kg (0 to 400 lb) of downforce

Integrated innovation is what operators will appreciate with the SeedStar 2 monitoring system and GreenStar™ 2 Display. An increasing number of acres combined with rising seed costs drive the need to easily understand planter functions and monitor performance. It is all about making every seed count and that is what SeedStar 2 delivers. 

The SeedStar 2 monitoring system is a full-feature, color, seed population monitor used in conjunction with the GreenStar family of displays. SeedStar 2 is compatible with the GreenStar 2 1800 and 2600 Displays, GreenStar 3 2630 Display, the Gen 4 4200 CommandCenter™ Display, the Gen 4 4600 CommandCenter Display, the 4240 Universal Display, and the 4640 Universal Display. SeedStar 2 is not compatible with the Gen 4 Extended Monitor. Conveniently, SeedStar 2 planting functions are fully integrated with the full spectrum of Precision Ag Technology applications—guidance, coverage maps, and field documentation can be shown all on one display.

When a SeedStar 2 system is used on a planter, there is no need for a ComputerTrak™ monitor. All vital planting information is displayed in one central, easy-to-read location.

SeedStar 2 features

SeedStar 2 full-screen planter run page

SeedStar 2 is a user-friendly system that has retained all the valued features of SeedStar and incorporated the next generation of enhancements. For example, on-screen color indicators show drive engagement/disengagement status. In addition, three color planter-at-a-glance bars (black, orange, or red) visually inform the operator of row population status.

Not only does SeedStar 2 incorporate the use of color, it also utilizes an intuitive icon and folder based operator interface. Icons are easy to understand across many languages and reduce the need for text. Icons for planter main run page, planter setup, seed/crop setup, totals, and diagnostics are located in the soft-key region of the display. Setup is performed by selecting the appropriate icon and then choosing the tabs to enter/select information.

The SeedStar 2 monitor offers all of the features and functionality of the ComputerTrak 350 monitor and much more. SeedStar 2 monitors the following planter functions:

• Row population/spacing
• Row failure
• Average population (entire planter and by variable-rate drive [VRD] motor section)
• Vacuum level
• Fertilizer pressure
• Acre counter
• Total acreage
• Tractor speed

In addition, planter operational information is available within the SeedStar 2 monitor system. Such operational information includes population charts, seed disk vacuum settings, and setting recommendations for the piston pump liquid fertilizer system.

All SeedStar 2 systems have the capability, through a single controller, to perform both the seed monitoring and variable rate drive functions. SeedStar 2 monitoring is required for VRD population control. Even though the planter may not be equipped with SeedStar 2 VRD, the SeedStar 2 monitoring system is available and will allow for future installation of VRD.

SeedStar 2 enhancements

The SeedStar 2 enhanced planter features include:

• GreenStar 2 display integration – eliminates the need to operate the GreenStar 2 2600 Display in the original GreenStar monitor mode or the use of dual displays.
• User-friendly, intuitive icons
• Half- or full-screen run page
• On-screen, color drive status – a quick glance at the display tells the operator if the half-width disconnect is engaged or disengaged.
• Three-color planter-at-a-glance population bar – a black bar indicates that population is close to target and within established limits; orange shows the population is above/below the alarm set point; and red signals the population is out of operating range or is not planting.
• Three-piece, color VRD indicator – each piece of the VRD gear pie turns green when the wheel motion sensor is active, planter is lowered, and drives are engaged.

SeedStar monitoring original features

SeedStar 2 retains all those SeedStar features that producers value and have come to expect:

• Planter at a glance – allows operator to view relative population levels of all rows on one screen.
• Automatic valve calibration – with the SeedStar VRD, this is now completed automatically. There is no longer a need to manually calibrate the hydraulic valves.
• Increased population updates – SeedStar will now update population levels once a second at planter start up then approximately once every three seconds.
• Mapping of actual seed rates – When combined with Field Doc™ system, actual and target seeding rates can now be mapped in APEX™ software.
• Reprogrammable utilizing controller area network (CAN) via Service ADVISOR™ diagnostics system.
• Improved diagnostics/event recorder – on SeedStar VRD planters, additional diagnostic information is available, as well as an event recorder to capture system performance data at a specific point in time.
• Ability to run motors at different population levels – on SeedStar VRD, operators running multiple motor systems can run each motor at a different speed, allowing different population levels within a planter.
• User-configurable high fertilizer pressure alarm – allows the operator to be warned when fertilizer pressure reaches a specific level.
• Automatic quick-start for SeedStar VRD – the operator no longer needs to press the quick-start button on end row turns to resume planting.
• Automatic tractor speed source selection – when equipped with an 8000/9000 Series Tractor, the system selects the radar speed or allows for manual speed input selection.

Crop yields have increased through the years along with the amount of residue left in the field after harvest. At the same time, tillage practices have changed, including different tillage operations which maintain large amounts of surface residue, and even no-till practices. Row cleaners are an essential tool in managing this increased amount of residue.

John Deere seeding group offers a variety of row cleaner options to meet the needs of a producer's operation. Compatibility varies by model, row spacing, and other planter equipment.

Screw-adjust, unit-mounted row cleaner

Screw-adjust, unit-mounted row cleaner

The screw-adjust, unit-mounted row cleaner is mounted directly to the face plate of the row-unit, placing the ground engaging components just in front of the row-unit opener blades and depth gauge wheels. This close proximity allows the gauge wheels to control the depth of the row cleaner as well as the row-unit. This compact design also allows greater compatibility with fertilizer openers and other planter attachments.

SharkTooth® wheels are standard equipment on the unit-mounted row cleaner. The swept-tooth design of the wheel provides a clear path for the row-unit openers while resisting residue buildup on the wheel. The screw adjustment knob is accessible through the top of the parallel arms, providing convenient access for adjustments. The row cleaner can be adjusted in 1.6-mm (1/16-in.) increments, providing plenty of flexibility to meet the needs of changing conditions.

Floating row cleaner with unit-mounted coulter

Floating row cleaner with unit-mounted coulter

The floating row cleaner allows a row cleaner to be used in conjunction with a unit-mounted coulter. This combination is often desired in heavy residue loads and reduced tillage planting conditions. The row cleaner provides a clear path for the row-unit, while the unit-mounted coulter helps penetrate tough soil conditions.

Accommodating the unit-mounted coulter means the residue wheels are farther forward from the row-unit face plate than in the case of the screw-adjust row cleaner. To maintain performance, this row cleaner has the capability to float above a defined minimum depth.

Standard depth-gauging bands on the wheels allow the row cleaner wheels to float independently of the row-unit openers, allowing both to perform in varying terrain. The unit may also be set in a fixed position by simply pinning through the bracket if desired. This row cleaner also features SharkTooth wheels as standard equipment.

The floating row cleaner and unit-mounted coulters are available on many planters as factory-installed equipment. As compatibility and details vary by model, review the following links for information on specific planter models.

• 1705, 1715, 1725, 1765NT, 1765, 1775 Flex, 1785 floating row cleaner
• 1775NT floating row cleaner
• 1795 floating row cleaner

NOTE: Screw-adjust row cleaners are not compatible with MaxEmerge™ 5e row-units with long parallel arms.

NOTE: DB models have the option for either unit-mounted coulter, screw-adjust row cleaners, or pneumatic row cleaners (only compatabile with MaxEmerge 5e or equipped ExactEmerge™ models). The DB60T is only available with a less row cleaner option.

SharkTooth is a trademark of Yetter Manufacturing, Inc.

RowCommand controls seed output

RowCommand on a MaxEmerge™ 5 row-unit

RowCommand on a chain drive MaxEmerge 5 row-unit

Controlling input costs and improving productivity are key producer requirements today. RowCommand is an effective, integrated John Deere solution designed to meet these intensifying needs. The RowCommand system manages seed output, reduces yield drag, and improves harvest capabilities on all Pro-Shaft™ driven row-units, and chain-driven MaxEmerge 5.

NOTE: Chain-drive RowCommand is only compatible with planters equipped with pneumatic downforce systems. On planters equipped with the heavy-duty downforce springs, potential chain interference may result and is not recommended.

NOTE: Chain-drive RowCommand requires some modification to brackets in order to function with corn finger pickup meters.

NOTE: Pro-Shaft drive RowCommand is compatible on MaxEmerge 5 row-units with vacuum and corn finger pickup meters. For mini-hopper row-units, RowCommand is compatible on vacuum meters only and is not compatible on corn finger pickup meters. Pro-Series™ XP row-units with corn finger pickup meters are not compatible with RowCommand.

RowCommand controls seed output by incorporating individual, low amperage clutches inside the Pro-Shaft and chain-driven gearboxes. Clutches are completely enclosed within the gearbox housing to protect them from the elements and harsh operating conditions.

When power is supplied, either manually or through John Deere Section Control software, clutches disengage the seed meters and seed flow stops. Controlling seed output at individual rows reduces overplanting in point rows and maximizes seed placement when entering/exiting headlands.

Components and operation

Electronic power modules shown on a 1775NT Planter

RowCommand clutch on MaxEmerge 5 with 105.7-L (3-bu) hopper

RowCommand is a simple and efficient solution to control individual row planting. This system does not utilize air to operate; therefore, no compressor, air lines, or valve modules are required.

RowCommand utilizes low-voltage controller area network (CAN) messaging to signal power to the desired clutches to stop planting or eliminates power to resume planting.

This means very little power is used in normal planting conditions, and in the event a clutch fails electrically, the meter will continue to plant.

The RowCommand system requires the following five basic components to operate: 

Clutches are protected within the sealed Pro-Shaft and chain-driven gearboxes for years of trouble-free operation and simple installation or removal. RowCommand has true individual-row control of up to 16 clutches or sections for planters larger than 16 rows.

Unique to RowCommand, the 16 available control sections can be configured based on operator preferences. For example, on a 1775NT 24-Row Planter, every two rows can be paired together for a total of 12 control sections, or control the outermost eight rows individually and the remaining inner rows paired together for 16 control sections.

While SeedStar with RowCommand has 16 control sections, a minimum of 152.4-cm (60-in.) wide sections are recommended for optimum Swath Control Pro™ solution capabilities. As with other Swath Control Pro products, an SF2 signal is the minimum level of accuracy recommend for operation.

Pro-Shaft drive RowCommand planters

RowCommand is available as a factory-installed option or as an attachment for field conversion attachments for the following Pro-Shaft drive planter models (see chart below).

Chain-drive RowCommand planters

In terms of planter compatibility, RowCommand for chain drive is designed for the following planter model configurations equipped with pneumatic downforce systems.

Chain-drive RowCommand and heavy-duty downforce

Chain interference with heavy-duty downforce

As seen in the image, chain interference may result when operating chain-drive RowCommand on planters equipped with short and long parallel arms and heavy-duty downforce springs.

NOTE: Chain-drive RowCommand is only compatible with planters equipped with pneumatic downforce systems. On planters equipped with the heavy-duty downforce springs, potential chain interference may result and is not recommended.

Chain-drive RowCommand with corn finger pickup meters

Bracket material removal

Due to the design characteristics of the chain-drive RowCommand clutch, some modification to the corn finger pickup meter drive bracket is required. As seen in the picture to the left, some material needs to be removed from the front of the meter drive bracket in order for the chain-drive RowCommand clutch to have sufficient space for installation.

NOTE: Chain-drive RowCommand requires some modification to brackets in order to function with corn finger pickup meters.

RowCommand ordering information

To add RowCommand to a model year 2009 and newer planter model listed above is simple. Pro-Shaft drive attachments for field conversion and chain-drive attachments for field conversion are available by planter model to add the appropriate number of clutches, EPMs, brackets, hardware and row-unit harnesses. For complete installation and part detail for the RowCommand conversion, please use the RowCommand compatibility tool per specific planter model.
 
RowCommand is compatible and available for model year 2003 (serial number 700101) to 2008 (725101) planter models listed above. In addition to the attachment for field conversion attachment, a planter mainframe harness, SeedStar 2 controller (wedge box), and additional CAN harnesses are needed.

Integrated Swath Control Pro

Coupling RowCommand with Swath Control Pro provides the ultimate in precision planting and productivity. One company, one integrated solution are what we offer by incorporating Swath Control Pro capabilities within the SeedStar 2 wedge box (controller). Unlike previous systems, no rate controller, additional harnessing, or components are required to achieve automated individual-row control.

SeedStar 2 monitoring, RowCommand, and Swath Control Pro activation from John Deere Precision Ag Technologies are all that is needed when ordering.

System requirements

RowCommand is a simple and efficient means to control individual row planting through the use of low-voltage electric clutches. When activated, each clutch consumes no more than 0.5 amps. By design, power is only supplied to the clutch when a signal is received to stop planting. In a normal planting condition, no power is supplied and the clutch is de-energized. 

Power for the RowCommand system is provided from the 9-pin ISO implement connector. All late-model 8X00 and 9X00 Series John Deere Tractors equipped with the 9-pin ISO implement connector are capable of supplying ample power for system operation.

Along with ample system power, a GreenStar display and SeedStar monitoring are required for operation and control interface. The GreenStar display is where system setup, control settings, and manual control functions are performed.

Seed variable-rate drive provides the ultimate planting productivity by utilizing one, two, or three hydraulic motors (varies by model) to turn the seeding drive shaft. Hydraulic control of the seeding drive allows for on-the-go seeding rate changes right from the display mounted inside the tractor cab. Combine this seeding flexibility with the map-based planting option, and seeding rates adjust automatically based on the prescribed map. 

Variable-rate drive offers the following advantages over common, ground, or contact-tire drive systems: 

• Rate changes are almost instantaneous; no ramp up or ramp down of system as in some competitive systems
• Permits the producer to match seed population based on different soil types or irrigation practices
• John Deere design provides added operator safety by eliminating any possible drive creep found in some competitive variable-rate drive systems

1755 equipped with variable-rate drive

1765NT equipped with variable-rate drive

Single- or dual-motor systems for variable-rate drives are available for all John Deere planters except the 1785 Rigid Frame. Variable-rate drive is available as a factory-installed option for all applicable planter models.

Single- or dual-motor systems are available as field-installed attachments for most planter models; however, a three-motor variable-rate drive field-installed attachment is not available.

Seed variable-rate drive requires the SeedStar™ monitor and a radar input signal. Either tractor or planter radar may be used. Planter radar is ordered separately.

NOTE: Peanut seed meter disks require the variable-drive transmission.

VRD shown on a 1775NT

The seed variable-rate drive provides the ultimate planting productivity by utilizing one, two or three hydraulic motors (varies by model) to turn the seeding drive shaft. Hydraulic control of the seeding drive allows for on-the-go seeding rate changes right from the display mounted inside the tractor cab. 

Combine this seeding flexibility with the map-based planting option, and seeding rates adjust automatically based on a prescription map.

Single- or dual-motor systems for variable-rate drives are available for all John Deere planters except the 1785 Rigid Frame. Dual- or three-motor drive systems are commonly used on larger (12-row and more) planters and offer the capability of half-width or three-section drive disconnect.

The VRD is available as a factory-installed option for all applicable planter models. Single- or dual-motor systems are available as field-installed attachments for most planter models; however, a three-motor VRD field-installed attachment is not available.

The seed VRD requires the SeedStar™ monitor and a radar input signal. Either tractor or planter radar may be used. Planter radar is ordered separately.

VRD offers the following advantages over common, contact-tire drive systems: 

• Almost instantaneous rate changes – there is no ramp up or ramp down of system as in some competitive systems
• Permits the operator to match seed population based on different soil types or irrigation practices
• John Deere design that provides added operator safety by eliminating any possible drive creep found in some competitive variable rate drive systems

Half-width drive disconnect

The half-width drive disconnect feature is excellent for the producer concerned with controlling seed costs. This feature helps the operator place seed in the desired area and limit the amount of costly overlapped planting. 

The half-width drive disconnect allows the operator to turn off half of the planter at a time for planting end rows, point rows, etc. Variable-rate-equipped planters require two drive motors to utilize the half-width disconnect feature. 

Half-width drive disconnect within frame control

With a 1765, 1765NT, and 1775 12-Row Planter, a single switch box is required for planters that are ordered with variable rate drive and half-width disconnect.

For the 1775NT, 1775NT Central Commodity System (CCS™), and 1795 Front-Folding Planters, the half-width drive disconnect switch is contained within the frame control box, conveniently located in the tractor cab. The function easily shuts off the drive for the left or right half of the planter row-unit seed meters.

Three-width drive disconnect

Three-width drive disconnect control

Three-width drive disconnect is an option on 1725 12-Row Planters and is base equipment on the 1725 16Row30 Planter. This feature is activated by three individual console mounted switches (control box), conveniently located in the tractor cab. The function easily shuts off the planter row-unit seed meters by one-, two-, or three-drive segments independently.

Granular fertilizer hopper and transmission

Granular fertilizer hopper and opener

Granular fertilizer is available for 1755, 1775, and 1785 Planters. Fertilizer hoppers/tanks and selected other equipment may not be installed to facilitate shipping. Fertilizer attachments place fertilizer only on 76.2-cm, 91.4-cm, or 96.5-cm (30-in., 36-in., or 38-in.) spacings. Some planter frame and row spacing combinations result in the opener offset 10.1 cm to 15.2 cm (4 in. to 6 in.) from the centerline of the Tru-Vee opener.

Hoppers hold approximately 249.5 kg (550 lb) of fertilizer for longer operating time between fill-ups. One hopper feeds two rows. Hopper lids provide a large opening for fast filling with less spillage. Hoppers pivot for easy dumping and cleaning. 

The transmission (two on 1775) has 24 sprocket combinations in consistent 6 percent increments to allow operators to apply fertilizer at the desired application rate. Depending on which auger is selected, a wide range of fertilizer rates can applied from 52.7 kg/ha (47 lb/acre) to 803.7 kg/ha (717 lb/acre). It requires openers or a surface application bracket.

Augers for granular fertilizer system

Low-, regular-, or high-rate feed augers are required to complete the granular fertilizer system. Augers move fertilizer from the fertilizer boxes to the opener. Regular- or high-rate augers are matched with the opener style selected and are available as a factory-installed option or as an attachment for field conversion. Low-rate augers are only available as an attachment for field conversion.

For 76.2-cm (30-in.) rows, the approximate rate of application is as follows:

• Low-rate augers – 52.7-139 kg/ha (47-124 lb/acre)
• Regular-rate augers – 105.4-533.5 kg/ha (94-476 lb/acre)
• High-rate augers – 183.8-803.7 kg/ha (164-717 lb/acre)

For 96.5-cm (38-in.) rows, the approximate rate of application is as follows:

• Low-rate augers – 41.5-208.5 kg/ha (37-186 lb/acre)
• Regular-rate augers – 82.9-418.1 kg/ha (74-373 lb/acre)
• High-rate augers – 124.4-626.6 kg/ha (111-559 lb/acre)

NOTE: Weight metered may vary from that indicated because the fertilizer attachment will meter by volume not by weight and because of differences in fertilizer density.

1770 granular fertilizer openers

Frame-mounted, single-disk fertilizer openers with cast spout are utilized on the 1775 12Row30 Planter. These openers are ideal for both conventional and no-till. The openers are adjustable to place the fertilizer in the soil next to the seed furrow for ideal nutrient placement and maximum plant uptake. A single gauge wheel allows the opener to follow the contour of the ground for ideal fertilizer depth placement. Single-disk fertilizer openers are compatible with frame-mounted coulters.

1755 and 1785 granular fertilizer openers

Granular fertilizer opener

Frame-mounted, double-disk openers and frame-mounted, single-disk openers for granular fertilizer are available on the 1755 and 1785 Planters. The frame-mounted, single-disk opener is available with a regular spout or cast spout. Fertilizer openers place the granular fertilizer into the soil for maximum plant uptake and are adjustable. Single-disk fertilizer openers are required for no-till, but are also suitable for conventional and reduced tillage. Double-disk fertilizer openers should only be used in conventional and reduced tillage conditions. 

• Single- and double-disk openers are compatible with frame-mounted coulters.
• Single-disk opener with cast spout is recommended for all soil conditions because it keeps soil from flowing into the furrow before fertilizer is delivered.
• The gauge wheel on single-disk openers will help gauge fertilizer application depth and minimize soil disruption.
• On 1755 8Row30 Planters, due to frame limitations, the granular fertilizer systems with single-disk openers can place fertilizer no closer than 12.7 cm to 15.2 cm (5 in. to 6 in.) to the seed furrow on rows 4 and 5.

1765NT tire contact drive system

The tire contact drive for mechanical seed transmissions is a great fit for the mid-to-large planter operator concerned with quick transport capabilities, lower maintenance, and positive seed meter drives. The tire contact drive system is a simple, reliable, and efficient way to power seed transmission and meters.

The tire contact system drives the seed transmission mounted above the inner planter ground drive tire. A turf tire engages the ground drive tire when the planter is lowered, automatically turning the seed transmission and seed meters. Automatic drive disconnect occurs when the planter is raised and the turf tire separates from the ground-engaging tire. The system eliminates clutches, countershafts, and manual transport disconnects needed on direct ground drive systems. Drive chains and sprockets are moved up and out of the soil and residue zone for excellent reliability.

Tire contact drive systems are base equipment on the 1765, 1765NT, 1775 12-Row, and 1785 Planters. Contact between the ground-engaging tire and seed transmission tire is positive. On all models mentioned, a spring set applies downforce of the turf tire assembly onto the ground-engaging tire. System slippage is also minimized because the planter drive tires track in the tractor tire tracks. Frame designs differ (such as tire width) and the following different downforce requirements exist:

• 1765 8-Row drives have 207.3 kg (457 lb) of downforce.
• 1765 and 1775 12-Row drives have 254 kg (560 lb) of downforce. 

The 1765 model uses one rear-mounted seed transmission. However, if the planter also has the fertilizer option, there is another rear-mounted transmission for the fertilizer drive. The 1785 Rigid Planters utilize one front-mounted seed transmission and if the planter is equipped with the liquid fertilizer option, another front-mounted transmission is utilized. The 1775 12-Row Planter utilizes two rear-mounted seed transmissions. Another rear-mounted transmission is used if the planter has the fertilizer option.
