Features
MaxEmerge 5 bundles the best of MaxEmerge XP and Pro-Series™ XP row-units to give you a unique planter solution. With more options and configurations, you’ll get difference-making versatility that easily adapts to your ag management plan.
It starts with optimal seed population that drives yield potential. An improved double eliminated helps achieve your desired population with a ride range of crop sizes. Improved side-hill performance of up to ¼ degree ensures you receive the full value of each seed when planting on terraces or rolling terrain. The vacuum air source from the Central Commodity System (CCS™) tank in the meter provides a debris-free environment for increased meter efficiency.
MaxEmerge 5 with 56-L (1.6-bu) hopper plus insecticide
MaxEmerge 5 with mini-hopper on 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.
Easily access the meter
Serviceability and changing crops have always been a focus of downtime and potential seed loss. The MaxEmerge 5 meter (shown on the right) is accessible without having to remove the box. The 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.
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
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.
Vacuum meter seed disks
The ProMax 40 Flat Disk is a flat-disk planting solution field-proven to work since 1991.
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 can operate 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.
ProMax 40 Flat Disc
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.
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 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
Double eliminator
Flat seed disc and 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.
Tru-Vee opener blade
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
1785 Rigid Frame Planter
The 1785 Rigid Frame Planter features a 7.6-cm x 17.8-cm (3-in. x 7-in.) front frame for fertilizer, a 17.8-cm x 17.8-cm (7-in. x 7-in.) rear frame, and heavy-duty drop-axle lift system.
Large-frame carrying wheels provide good flotation and are located in front of the 17.8-cm x 17.8-cm (7-in. x 7-in.) frame tube to maximize planting unit location. The 1785 is a versatile planter recommended for conventional, reduced-till, double-crop, and no-till planting conditions.
Alternating row-units are equipped with long parallel arms so they are offset to the rear of the machine approximately 17.8 cm (7 in.). This alternate spacing permits trash and soft soil to flow easily through the narrow row spacings of 38.1 cm, 45.7 cm, and 48.3 cm (15 in., 18 in., and 19 in.). All rows are in line for easy bulk seed filling.
NOTE: Firm ground conditions are recommended for best planter operations.

Fertilizer capabilities
The 1785 Rigid-Frame Planter may be equipped with liquid or granular fertilizer systems. On single-disk fertilizer openers, an alternate downforce spring (A50733) is recommended in tough, conservation conditions. On the 8Row30 Planter, due to frame limitations, the single-disk fertilizer openers on rows four and five can only be set 12.7 cm to 15.2 cm (5 in. to 6 in.) off the row center line.
Integrated innovation is what operators will appreciate with the SeedStar 2 monitoring system and GreenStar™ 2 Display.

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 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 is compatible with the RowCommand™ system and Section Control

- 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.
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 compatible 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.
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.
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.
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.
56.4-L (1.6-bu) box with granular chemical option
Today's planter owners depend on chemicals to control crop pests such as insects or weeds.
MaxEmerge™ 5 planters with 56.4-L (1.6-bu) seed hoppers or mini hoppers are available with a variety of granular chemical application attachments that allow operators to apply insecticide only, herbicide only, or insecticide and herbicide at the same time.
Roller meter and fluted meter
There are two different types of rollers available for the chemical meter.
-
The meter/roller (on the left) features a white plastic cupped meter roller. It is base equipment for all chemical applications.
-
Application rates of up to 226.8 g (8 oz) per 304.8 m (1000 ft) are possible.
-
The conventional fluted meter roller (on the right) is available through service parts. It can apply rates up to and greater than 226.8 g (8 oz) per 304.8 m (1000 ft).
Of the two meter rollers, the cupped roller will cover about 95 percent of producer chemical application needs. The cupped roller/meter will reduce chemical leakage on the end rows and in transport.
These features are common to all granular chemical application attachments:
- Large polyethylene hopper holds 31.8 kg (70 lb) of insecticide or herbicide (15.9 kg [35 lb] each when used together).
- Hoppers equipped with single meters are molded with a sloping floor/side for good run out of chemicals. Hoppers equipped with dual chemical meters do not have the sloping floor design.
- Single meter hoppers cannot be converted to dual meter chemical operation; the sloping floor design will not accept the box divider.
- Large detented knobs have easy-to-read digits for quick, accurate settings.
- Lid is attached to hopper to ensure chemical is always enclosed during use.
- Individual manual row-unit shutoff is standard equipment.
- Adjustable orifice in chemical meter determines chemical delivery rate. Rotating fluted rotor ensures there is always chemical material above the orifice.
- Plastic metering components resist corrosion.
A unique drive system automatically engages and disengages for each hopper. There is also an easy-to-reach push/pull knob for disengaging the drive when it is desirable to discontinue chemical application.
The Pro-Shaft™ drive driven granular chemical system is ideal for fields that have high levels of residue or where a unit-mounted coulter or row cleaner is used. The system performs well in high residue and damp soil conditions due to the lack of chains and sprockets.
NOTE: The Pro-Shaft drive will not shut off with RowCommand™ system because it is driven directly off of the hex shaft. The chain drive system will disengage with the seed meter when using the RowCommand system.
Block manifold delivery system
Block manifold distribution
Delivering consistent and accurate fertilizer rates to each row is critical with any liquid fertilizer delivery system. The John Deere liquid fertilizer system utilizes 12-port block manifolds to equally distribute flow to the opener or in-furrow method of application. Liquid is distributed to each row through a 7.6-mm (0.3-in.) hose.
There are check valves at each row to ensure the system remains primed and flow stops immediately when planter is lifted. An orifice is located in-line and provides the restriction needed to achieve desired system pressure for excellent rate accuracy.
This delivery system will operate between 103.4 kPa and 620.5 kPa (15 psi and 90 psi), depending on the orifice size and rate. System pressure should not exceed 689.5 kPa (100 psi). Four orifice sizes allow operators to achieve a variety of rates all with optimal system performance and row to row accuracy. See rate chart below for model by model minimum and maximum application rates.
An 80-mesh washable screen is in place between the tank and the pump. It is essential to have this screen (AA40216) and associated fittings in place ahead of the fertilizer pump, even if not using a factory tank and quick-fill system. This screen is utilized to catch any blocks in the system caused by liquid fertilizer impurities. It is not recommended to use the 50-mesh screen.

Connected Support technology
When you buy John Deere equipment, you expect reliability. You also know that problems can happen, and a product is only as good as the support behind it. That’s why John Deere equipment is prepared with technology that senses potential issues and can alert you and your dealer promptly—in the cab or anywhere you are.
John Deere Connected Support is a revolutionary change to support that leverages technology and the connectivity of JDLink™ telematics to prevent downtime and resolve problems faster. These tools decrease downtime by an average of 20 percent, enabling faster responses to unexpected problems and reducing technician trips to your machine. For some issues, unplanned downtime can even be prevented altogether through prediction of the issue.
With your permission, John Deere Connected Support:
- Keeps you running by monitoring machine health and promptly alerting you and your dealer of issues
- Saves time by remotely viewing in-cab displays, reducing trips to the machine
- Reduces or even eliminates technician trips to a machine through remote diagnostic and remote software reprogramming capabilities
- Connects experts with the information needed to respond to downtime faster and prevent it altogether
With more than a decade of experience leveraging connectivity to solve problems, no one else has the experience, tools, and knowledge to keep you running as John Deere and your John Deere dealer can. Connected Support is an in-base feature on all John Deere products with factory- or field-installed JDLink.
