It is very challenging to get the crop planted during the optimum planting window or as close to the optimum planting day as possible. Rate-of-yield loss accelerates greatly after the optimum window has passed. This is especially true in the northern U.S. and Canada. ExactEmerge maintains accurate speed placement at higher speeds; growers can avoid missing that peak planting time, thereby helping to get the highest crop yields.
Yield loss after optimum planting day
With the BrushBelt trench delivery system, the spacing in the trench does not change from even to uneven terrain. This can be a problem with a traditional seed tube. Seed bounce and ricochet may occur as slopes increases, ultimately decreasing seed spacing performance.
The design of the BrushBelt system provides the best solution for the lowest release of seed to the bottom of the trench. The use of a brush provides the meter with an infinite amount of placement opportunities for each seed. This is what gives producers the confidence that every seed will have the desired spacing that a seed tube cannot provide.
Maintenance-free BrushBelt system
When the brush comes around the pulley, it expands and allows the seed to be transferred from the bowl to the brush very easily. The brush then carries the seed down toward the trench, ensuring that there is no movement as it moves down the length of the cartridge.
Once the brush reaches the lower pulley, the BrushBelt system expands again to loosen the grip on the seed, and the centrifugal force releases the seed. Another advantage with the BrushBelt system and cartridge at all speeds up to 16.1 km/p (10 mph) is the ability to match the seed rearward trajectory to the forward ground speed of the planter. This provides a dead drop of the seed with no bounce and no roll at the bottom of the trench.
BrushBelt conditioner engages brush bristles
John 91黑料专区鈥檚 ExactEmerge cartridge is self-cleaning. When an operator uses seed treatments or is forced to plant in less than ideal soil conditions, the design of the trench delivery system sheds buildup from the BrushBelt. A brush conditioner is located at the bottom of the cartridge to remove remaining residue and prevent the bristles from sticking together.
Brush proximity helps clean sensor
Another advantage over a seed tube is that the BrushBelt system also acts as a cleaner to the seed sensor compared to a seed tube.
Sensors for trench delivery system
Reflective seed sensor
Sensor on trench delivery system
On all ExactEmerge row-units, each cartridge is equipped with sensors. As the seeds are being delivered through the BrushBelt delivery system controls, they pass the reflective seed sensor. The delivery system slides every seed past the seed sensor to read and send the signal to the controller. The seed sensor and design can provide sensor performance at higher seeds per second with no population adjustment as needed with seed tube sensors. This seed sensor data is actual row-unit performance data. In comparison, seed tube sensors add 10 percent population in soybean planting to adjust for the seeds missed due to placement within the seed tube. The BrushBelt system holds each seed in place until released in the trench, allowing the seed sensor a more accurate read.
BrushBelt removed from trench delivery system
The BrushBelt system requires no maintenance and has a wear life designed to match the wear life of the other wear components. Since operations vary, as do soils and field content, it is recommended to replace the BrushBelt after noticeable wear or decreased performance.
Changing the belt is easy. One latch removes the meter over the trench delivery system. Grab the cartridge by the grip and pull toward the body, releasing it from the electric motor fitting. Lift the trench delivery system up and remove the sensor wiring harness to completely pull the cartridge out of the row-unit.
There are two plastic covers that snap off to uncover the belt; remove the covers and then twist the circular spring tensioner dial with the yellow arrow on it to release the tension on the springs. Once tension has been removed, pull the belt out. It is also recommended to change the stainless-steel wear strip at this time as well, which also slides right out of place without the use of tools.
NOTE: It is recommended to use a talc/graphite mixture with ExactEmerge. Best results have been 80 percent talc and 20 percent graphite. For certain regions and territories, talc and talc/graphite mixes are restricted from use; in this case, use a wax-based fluency agent.
SeedStar 5 screen example
SeedStar 5 is the latest monitoring software for John 91黑料专区 planters available for Model Year 2025. This system is paired with G5 displays and Implement Ethernet to provide high-definition documentation, faster data speeds, and more information in the cab.
Requirement:
IRHD system
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.
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 G5 Display with SeedStar 5. As shown below, operators can view ground contact or applied downforce using the toggle button.

IRHD accumulator
The IRHD actuator is the foundation of ensuring accurate seed depth and seed-to-soil contact at higher planting speeds up to 16.1 km/h (10 mph). The newly redesigned IRHD actuator was designed with durability and optimal performance in mind. Consisting of a valve, pressure sensor, cylinder, and now, two accumulators, the new design allows the operator to reduce downtime with recharges instead of replacements. With two rechargeable nitrogen accumulators built into the new IRHD actuator, it maintains performance, even at low nitrogen levels. This allows reduced downtime for the operator, and optimal performance over entire operating range. Pressure control from the IRHD actuator ensures optimal system performance by dampening shocks from field obstacles while operating in the field. The reduction of shock loads prevents excessive wear and broken row unit components due to the new robust and durable design. Frequently worn parts such as the accumulator pistons and seals can be replaced. The actuator rod has an internal retention feature to prevent oil loss in the event of a row unit failure.

Downforce and margin example
The functional features of the integrated system are the same as the standard pneumatic system, explained above, with the addition of control through the display.
Active downforce compressor assembly
A hydraulically driven compressor works with the G5 Display with SeedStar 5 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.
Active pneumatic downforce is available as factory installed or as an attachment for field conversion.
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 display.
When adjusting the amount of row-unit downforce using the 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 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.
Features include:
Pneumatic downforce compressor and gauge
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.
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).
Coulter combo row cleaner
Easy Adjust row cleaner
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.
4600 CommandCenter鈩� Display and 4640 Universal Display view for row cleaners compatible with SeedStar 4HP
G5 Universal Display for row cleaners compatible with SeedStar 5HP
With the Easy Adjust row cleaners on ExactEmerge鈩� 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 4 HP, the row cleaners are completely integrated into the John 91黑料专区 Gen 4 4600 CommandCenter display or 4640 Universal Display. For growers using SeedStar 5HP, a G5 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 Precision Upgrade 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庐 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.

Variable-rate drive system
The variable-rate drive on the 12Row, 16Row, 18Row, and 24Row integral planter completing packages provide the ultimate planting productivity by utilizing three hydraulic motors 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.
The variable-rate drive requires the SeedStar鈩� 2 monitor and a speed input signal. Either tractor or planter radar may be used, or a global positioning system (GPS) speed signal. The radar speed input signal is recommended. Planter radar is ordered separately.
The variable-rate drive offers the following advantages:
Three-width drive disconnect control
Three-width drive disconnect is base equipment on the custom 12Row, 16Row, 18Row, and 24Row integral planter completing packages. 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.
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 91黑料专区 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
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庐 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
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鈩� 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鈩� models). The DB60T is only available with a less row cleaner option.
