The ExactRate liquid fertilizer system is a factory-installed solution that provides you with accurate nutrient placement during planting. Previously, you would have to deal with the inconvenience of cumbersome aftermarket systems for a hydraulically driven variable-rate solution. With ExactRate, John Deere delivers a complete planting solution for liquid fertilizer users. You can choose between in-furrow or offset delivery methods. This system delivers:
Up to 20 percent more accurate nutrient placement in a turn compared to a non-turn compensating systems
1 to 12 percent (4.3 percent on average) reduction in inputs through row-by-row section control
Ability to run up to 16.1 km/h (10 mph)
Closed-loop speed and rate change compensation
Full integration into the 4600 CommandCenter™ and 4640 Universal Display
ExactRate nozzle body
The ExactRate liquid fertilizer system is designed to take full advantage of the capabilities of ExactEmerge™ and MaxEmerge™ 5e planters. This factory-installed liquid fertilizer system delivers the same value as your electric drive planter including working at speeds faster than the traditional 8.05 km/h (5 mph), turn compensation, and row-by-row section control, all while accurately compensating for varying rates and speed changes. Additional features include row-by-row flow detection, as-applied documentation, and variable-rate capabilities, providing operators full integration into the 4600 CommandCenter or 4640 Universal Display.
Fertilizer flows from the tank to the pump, through a strainer and boom isolation valve, through a central flowmeter, and out to each nozzle body and row-unit for accurate delivery. The system is closed loop, meaning the pump and nozzle body duty cycle both adjust based on feedback received from the pressure sensor and central flowmeter. This design helps maintain an accurate application rate.
NOTE: ExactRate is not recommended for products that require agitation to maintain suspension.
Pump assembly at rear of planter
Instead of a tire-contact drive, a hydraulically driven centrifugal pump eliminates chain and sprocket adjustments to provide more speed flexibility over the entire rate range. This pump allows for a wide range of rate capabilities as well as strong durability. The wet seal design helps protect the pump if it is accidentally run dry for a short time.
A strainer helps collect suspended particles and prevent them from causing blockages in the distribution system and nozzle bodies.
Boom isolation valve
The valve prevents the tank from draining out if there is a leak in the distribution system. If the pump is on, the valve opens to allow flow. When the pump is off, the valve closes.
Central flowmeter and pump pressure sensor
The central flowmeter and pump pressure sensor provide the rate control system feedback on flow and pressure to ensure an accurate application rate across the entire planter width. The flowmeter also supplies the as-applied rate data.
Keypad at rear of planter
Just like on the sprayers, the keypad at the rear of the machine lets you conveniently perform a nozzle flow check to ensure product is coming out of each row before going to the field.
The ExactRate liquid fertilizer system does not have direct injection capabilities on the product being applied. If direct injection is needed on the secondary product, an additional rate controller is required.
NOTE: ExactRate system and John Deere Rate Controller 2000 with Raven ICD Direct Injection system is supported. ExactRate system and GreenStar Rate Controller with Raven ISO Direct Injection system is not supported.
Distribution system and nozzle body
Distribution system and nozzle bodies routed on the wing of a 12-row 1775NT
The 2.5-cm (1-in.) stainless-steel distribution lines not only reduce corrosion, they also provide a clean integrated look. The distribution system is pressure tested at the factory to reduce the risk of leaks.
John Deere has leveraged ExactApply™ technology and capabilities from the sprayers to enable row-by-row section control and turn compensation that matches the high-performance planters. With ExactRate, there are no orifice changes for rate or speed adjustments, saving you time and effort while limiting exposure to product. Pulse-width modulation technology varies duty cycle (opening and closing of the valve) in the nozzle bodies in conjunction with flow and pressure measured from central flowmeter and pressure sensor controlling the system pump. The ExactRate liquid fertilizer system uses one nozzle body for two rows, limiting the number of parts and complexity on each machine. While you’re in the cab, you’ll be able to keep an eye on each row with flow detection integrated into the Gen 4 display. The system will warn you if it detects a variance in an individual row’s flow. A pressure sensor integrated into the nozzle body will detect a flow reduction or overapplication on the row.
The ExactRate liquid fertilizer system is compatible with the John Deere Rate Controller 2000 and GreenStar™ Rate Controller if a producer wants to apply a second product using a separate distribution system.
ExactRate app on Gen 4
Easily adjust target rate and speed without leaving your seat. With turn compensation, inner and outer rates are automatically adjusted to maintain consistent application across the full width of the planter. This ultimately reduces the risk of seed burn by over application (turn compensations require a global positioning system [GPS] receiver). Another helpful feature is row-by-row section control for reduced overlap on headlands and waterways. Gen 4 Documentation creates as-applied maps showing what product was applied where, providing accurate record-keeping.

Custom rates allow for individual row population control and row-by-row documentation where up to six different rates can be assigned across an up to 48-row planter. This allows growers interested in planting seed corn with ExactEmerge or MaxEmerge 5e the capability to assign specific populations to male and female rows for planting. This feature can also be used to create tram lines or other applications where custom rates by row are needed.
NOTE: Individual rates are tied to varieties, so each individual rate needs a unique variety name.
NOTE: Advanced rates are not compatible with prescriptions or they cannot be run at the same time.
Determine optimum settings without being in the cab
The first day of planting season can be as productive as the last with mobile row-unit runoff. The mobile row-unit runoff activation on the planter main controller (PMC) allows operators to make adjustments to maximize row-unit performance from a mobile device at the rear of the planter for both preseason and in-season use - all enabled through the PlanterPlus™ app.
Mobile row-unit runoff allows growers to perform test-stand functions from a mobile device connected to the planter.
The row runoff test provides complete diagnostic checks both preseason and in season. With the row-unit runoff test, the operator can make adjustments from the mobile device, including vacuum pressure, to determine the optimum meter and vacuum settings. This app functionality will help avoid making trips to the cab while validating meter performance.
During preseason planter inspections and set up, utilize the meter performance test to validate meter accuracy, similar to a test stand without leaving the farm. Test all systems on the planter, not just the meter, providing confidence that all planter systems are ready to plant. Reports are generated from the test providing information the operator can save and send for future reference.
Before heading to the field, the operator will benefit from knowing the best row-unit and vacuum settings for each variety selected to plant that spring.
Watch this video to see mobile row-unit runoff in action.
Mobile row-unit runoff will work with any model year 2015 or newer ExactEmerge™ or MaxEmerge™ 5e equipped planter. Mobile row-unit runoff can be added with attachment AA93169.
For model year 2018 and newer ExactEmerge planters, mobile row-unit runoff is included in base equipment.

Follow the mobile runoff ordering and software push guide below for ordering and installation.
Terraces or waterways are two of many field obstacles that make planting on a curve challenging. When planters utilize drive shafts, they are not able to control each individual row-unit; as a result, planting on a curve presents an issue of maintaining 100 percent population. Since the inside rows are moving slower than the outside rows, the inside rows will be over populating while the outside rows are under populating.
With ExactEmerge™ planters and equipped MaxEmerge™ 5e planters, the curve compensation feature allows each row to receive an individual signal based on the speed at which the row-unit is moving, maintaining the correct population across the width of the planter. Without curve compensation, there could be as much as a 24 percent drop in population accuracy, which is equivalent to 8,600 seeds per acre when planting at 36,000 seeds per acre. Curve compensation measures acceleration within the main planter controller and utilizes speed inputs to ensure each row has the desired population accuracy.
IRHD has been specifically designed to meet the needs of producers that are looking to adjust to the toughest field conditions and provide maximum yield potential from field to field, season after season. IRHD works as a closed-loop downforce system that reacts quickly on an individual row basis to changing soil conditions supporting increased ground contact, which can lead to improved seed depth consistency. When setting planter downforce margin, the system will apply the needed downforce by row to maintain ground contact. From the factory, the margin will be set at 45.4 kg (100 lb), changes may be required based on varying field conditions.
The system allows operators to maintain gauge wheel ground contact leading to desired seed depth placement. IRHD can adjust five times per second and make adjustments of 45.4 kg (100 lb) in less than a second. The system has a total range of applied downforce from 22.7 kg (50 lb) to 204.1 kg (450 lb) and utilizes the power beyond circuit on the tractor. IRHD is 58 percent faster than the active pneumatic downforce solution. Fast reaction and increased ground contact can lead to improved emergence. With uniform emergence, some studies have shown a yield impact from 5 percent to 9 percent.
IRHD is controlled through the display with SeedStar™ 3 HP or SeedStar 4HP. As shown below, operators can view ground contact or applied downforce using the toggle button.

Hydraulically driven compressor
The hydraulically driven air compressor can deliver up to eight times the air flow when compared to the electric compressor, allowing for more and faster downforce changes to be made. This more robust design features a 37.8-L (10-gal.) storage tank across all models with active downforce.
At approximately 15.1 L/min (4 gpm), hydraulic demands are low and ties into the machine’s lift and Central Commodity System (CCS™) hydraulic circuit so it does not require any additional selective control valves (SCVs). The SeedStar XP, SeedStar 3 HP, and SeedStar 4 HP monitoring systems work with the compressor. SeedStar 3 HP and SeedStar 4 HP monitoring systems work with the compressor and valve assembly to regulate air to downforce springs, enabling the active control, pneumatic closing wheels, and pneumatic row cleaners.
Pneumatic downforce spring
Each row-unit has a single rubber air bag located between the parallel arms. The air bags are hooked in parallel so that air can be added or released from all rows at once from one location.
The individual pneumatic downforce air bag assemblies, air compressor units, and 9.5-mm (3/8-in.) delivery lines are also available as an attachment for field conversion.
Row-unit downforce planter run page
SeedStar XP downforce planter run page
Active downforce control is integrated into SeedStar XP, SeedStar 3 HP, and SeedStar 4 HP monitoring systems.
Margin is the amount of weight riding on the depth gauge wheels that ensures desired firming of the seedbed as set by the operator.
Once a target margin has been defined, enter the value into the display and let active downforce do the rest. The system will actively adjust the air pressure in the air bags to maintain a constant margin across the planter. The changes in air pressure will change the amount of downforce placed on the row-unit, compensating and reacting for varying conditions through the field whether it is different tillage practices, soil types, or moisture.
Set point row-unit downforce
Pneumatic downforce control in GreenStar 2 Display
Air compressor mounted on 1775NT outer hitch
On set point, the air compressor will be mounted on the outer hitch or frame assembly. Since the electric air compressor assembly is mounted on the outer hitch (as noted in the picture above) or frame, adjustments for row-unit downforce and related system pressures will be made electronically with the GreenStar display.
When adjusting the amount of row-unit downforce using the GreenStar display, the operator will select the amount of downforce (kg [lb]) to be applied across the planter. Depending on the soil conditions at hand, the operator might need to adjust the relative amount of row-unit downforce being applied during the planting operation. The integrated pneumatic downforce controls within the GreenStar display will only allow for set-point operation and not automatic control as the planter is operating in different soil conditions. The pneumatic downforce system does not have the capability to automatically adjust downforce.
Pneumatic downforce provides convenient, simple adjustment of downforce for the whole planter from one location. The amount of downforce applied is infinitely adjustable from 6.8 to 181.4 kg (15 to 400 lb). Pneumatic downforce provides more consistent downforce throughout the range of row-unit travel than mechanical spring downforce systems.
9.5-mm (3/8-in.) air delivery line instead of the 6.4-mm (1/4-in.) line used on model year 2010 and older planters.
Air compressor assembly increased duty cycle. With this compressor, it provides a 47 percent increase in maximum air flow delivery compared to the prior air compressor.
Pneumatic air bags with 9.5-mm (3/8-in.) air line inlets that have greater durability.
Downforce and margin example
A - Margin – amount of additional downforce applied to a row-unit above and beyond what is required for penetration to achieve planting depth. This additional weight will ride on the depth gauge wheels.
54.4 kg (120 lb) + 36.3 kg (80 lb) = 90.7 kg (200 lb) – 68 kg (150 lb) = 22.7 kg (50 lb) of margin
B - Weight of row-unit - 54.4 kg (120 lb)
C - Downforce – force that is applied to the row-unit by the air bag circuit - 36.3 kg (80 lb)
D - Resistance from soil - 68 kg (150 lb)
Active downforce compressor assembly
A hydraulically driven compressor works with the SeedStar XP, SeedStar 3 HP, and SeedStar 4 systems to automate downforce control. Just set the row-unit target margin value and the active pneumatic downforce system works automatically. The system will make sure the planter maintains this value, achieving precise soil penetration, and consistent planting depth, without sidewall soil compaction. From the factory, the system is set at 45.4 kg (100 lb) target downforce margin but may be modified for varying field conditions. This frees the operator from constantly making manual downforce adjustments as conditions change.
This system offers a split-rank control feature for 1795 and DB Split-Row Planters. On split-row planters, active downforce will control the front and rear rows independently. This compensates for differing downforce requirements between the ranks that can be caused by things like different tillage or insecticide attachments and will help maintain an accurate planting depth and consistent margin across all the rows.
An improved compressor is used to charge the pneumatic system. This compressor can be located on the planter frame or in the tractor cab if desired. A gauge at the compressor indicates the amount of downforce being applied.
Integrated pneumatic downforce system
The functional features of the integrated system are the same as the standard pneumatic system, explained above, with the addition of control through the GreenStar display.
Heavy-duty adjustable downforce springs
Heavy-duty adjustable downforce spring
Planter row-unit downforce is an important factor to ensure consistent and proper depth control. The heavy-duty adjustable downforce feature provides up to 181.4 kg (400 lb) of downforce. There are four settings available to allow the operator to choose the amount of downforce required for the condition: 0 kg (0 lb), 56.7 kg (125 lb), 113.4 kg (250 lb), and 181.4 kg (400 lb).
Easy Adjust row cleaner and coulter combo provides a pneumatic row tillage solution that is controlled from the seat of the tractor.
Every decision to make an adjustment during spring planting reduces the acres planted per day and can increase or decrease profitability. An adjustment that can be overlooked is row cleaners due to planter size, difficulty to make the adjustment, and varying conditions across fields and time.
GreenStar™ 3 2630 Display view for row cleaners compatible with SeedStar™ 3 HP
4600 CommandCenter™ Display and 4640 Universal Display view for row cleaners compatible with SeedStar 4HP
With the Easy Adjust row cleaners on ExactEmerge™ planters, operators now have a pneumatic solution to make on-the-go adjustments that is controlled directly from the seat of the cab. They can be raised from the cab as needed with the push of a button for wet areas, waterways, or end rows. For growers using SeedStar 3 HP, the row cleaners are completely integrated into the John Deere GreenStar 3 2630 Display as well as the Gen 4 4600 CommandCenter display or 4640 Universal Display. For growers using SeedStar 4HP, a 4600 CommandCenter display or 4640 Universal Display is required.
The Easy Adjust row cleaners have the capability to save three presets for varying ground engagement based on field conditions. The system is controlled in three sections: at each wing as well as the center (frame or wheel) track rows. The pneumatic lines use air from the active pneumatic downforce compressor, requiring no additional compressor to be installed on the planter. The Easy Adjust row cleaners utilize down and up force air bags. The adjustable air pressure setting for each bag allows the operator to set the ride of the row cleaner depending on the field conditions and the desired results. Making these on-the-go adjustments from tractor cab increases productivity and performance during planting.
For Easy Adjust row cleaner performance upgrade kit options, see the ordering guide.
The row cleaner-only option utilizes parallel linkage to provide the floating action growers require in their fields. Parallel linkage allows for the unit to float up and down in the situation of hills or hard objects. The cleaner and coulter combo does not have parallel linkage, however, the row cleaners have floating rings installed to help provide the same benefits.
The row cleaners utilize the field-proven SharkTooth® design. Row cleaners play a major role in maximizing yield toward uniform emergence, reducing row-unit bounce, and maintaining proper depth. The Easy Adjust row cleaners provide growers with quick and stress-free solutions to customizing the planter in variable field conditions. They are available on most ExactEmerge and MaxEmerge 5e equipped planters.
SharkTooth is a trademark of Yetter Manufacturing Incorporated.
Pneumatic closing wheels are compatible with MaxEmerge™ 5e and ExactEmerge™ row-units. They are available on the following models from the factory: 1775NT, 1795, and DB60 models. The pneumatic closing wheels give operators the ability to adjust closing wheels in seconds without leaving the cab of the tractor.
Using the GreenStar™ 3 2630 Display, pneumatic closing wheels can be adjusted to 25 different positions. From the factory the system is setup with two sections, the outer wings and center frame. With this system, producers will see up to a 76 percent increase in consistent force applied at the closing wheel. Consistently applying the correct force at the seed trench is one of the key elements of supporting improved emergence. Studies show potential yield impact on corn from even emergence from 5 percent to 9 percent*.
NOTE:Pneumatic closing wheels can be purchased for existing MaxEmerge 5e and ExactEmerge planters as an aftermarket field kit. Both rubber tire and cast-iron closing wheels are compatible.
Refer to the operator’s manual for guidance on settings, including when upgrading from springs to pneumatic.
