John Deere 1725C Planter
Achieve accuracy with Curve Compensation
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.
Easy Adjust row cleaners
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.
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.

Increase productivity with ExactEmerge™ trench delivery system and BrushBelt™ delivery system
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.
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.
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 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.
John Deere’s 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.
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.
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.
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.
Mobile row-unit runoff
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 EquipmentPlus 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.
