John Deere 1725NT Planter

Screw-adjust unit-mounted row cleaner

Row cleaners are a valuable tool in reduced tillage planting conditions. The row cleaner helps to clear residue from the path of the opener, ensuring good row-unit operation. The row cleaner utilizes two angled wheels which engage the soil surface and residue, sweeping them aside.

Row cleaners provide many agronomic benefits, including quicker soil warmup and germination, and reduced hair pinning of residue into the seed furrow. Row cleaners can also provide a smoother ride for the gauge wheels, resulting in less row-unit bounce and a more uniform seeding depth.

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

SharkTooth wheel

The unit-mounted row cleaner features the SharkTooth wheel. The beveled, sharpened edge of the teeth on the SharkTooth aggressively cut tough residue that lies in the path of the row-unit. The curved tooth design sweeps a clear path for the openers and resists residue buildup.

The wheels are arranged in a staggered fashion with one wheel leading the other, ensuring complete clearing of the row-unit path. The wheels can also be run side-by-side if desired, by simply relocating the wheels to existing holes on the row cleaner bracket.

The bearing on the SharkTooth wheel is sealed and requires no regular maintenance. Bearing shields are used between the wheel and the mount bracket to prevent residue wrapping and buildup around the bearing housing.
 

Adjustability

Row cleaner adjustment knob

The unit-mounted row cleaner offers a convenient screw adjustment feature for changing the depth setting. The acme screw is enclosed within the structure of the mounting bracket, providing protection from the elements.

The adjustment knob for the screw adjustment is accessible from the top of the parallel arms. The knob can be adjusted by hand, or by using a socket.

The adjustment is detented in 1.6-mm (1/16-in.) increments, allowing for quick, easily repeatable adjustments across all rows of the planter.

An indicator rod and scale on the front of the row cleaner bracket indicate the current setting. If a condition is encountered where use of the row cleaner is not desired, it can be set so that the wheels do not engage the soil surface.

Operational notes and compatibility

Use of row cleaners is not recommended when surface application pre-plant herbicide is used prior to planting. When using pre-plant incorporated herbicide, the row cleaner should be adjusted to minimize soil disturbance so as not to reduce the effectiveness of the incorporated herbicide.

Drive chain shields are recommended for use with row cleaner attachments.

Two different models of screw-adjust, unit-mounted row cleaners are available; the standard row cleaner for 762-mm (30-in.) row spacing and the narrow row cleaner for 508-mm (20-in.) or 558.8-mm (22-in.) row spacing.

NOTES:

1. Screw adjust, unit-mounted row cleaners are fully factory installed when ordered with the planter
2. Not compatible with use of frame-mounted coulter
3. Row spacing less than 762 mm (30 in.) requires the narrow row cleaner option.
4. For 1795 12/23, 12/24, 16/31, and 16/32 row machines, unit-mounted row cleaners are provided on the front rank of rows only.
5. For DB60 47R15 machines, unit-mounted row cleaners are provided on the row-units with short parallel arms only. They provide the 24 rows set on 762-mm (30-in.) spacing row cleaners.
6. Not compatible with the use combination of long parallel arms and MaxEmerge 5e row-units.

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 tubes. 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 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 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.

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.

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.

Stack-fold planter frame

1725NT Planter frame

The 1725NT utilizes an integral, stack-fold frame that allows for a transport width of approximately 3.05 m (10 ft) and a height of just over 4 m (13 ft). Operators who drive on narrow roadways or work in small fields will find the narrow transport frame, without lift-assist wheels, to be especially useful in situations where maneuverability is limited.

This design also allows for the vacuum to be integrated into the frame without adding clutter to the bar. This means a cleaner look with better visibility from the operator station.

The 1725NT also includes 40.6-cm (16-in.) notched disk markers in the base machine, with an option for less markers. These markers act independent of the frame position and are controlled by a selective control valve (SCV). The notched disk design allows for a more aggressive marking capability, especially in minimum-till or no-till conditions.

Vacuum automation screen

Vacuum control has been defined. Before vacuum automation, an operator set the vacuum level by adjusting the hydraulic flow through each selective control valve (SCV). Many variables altered the vacuum level while the hydraulic flow stayed constant. This could have resulted in under or over populating, which may have impacted singulation. With vacuum automation, all that needs to be done is set the desired vacuum level and let the monitor do the work of adjusting the hydraulic flow. Should vacuum changes occur, the software in the monitor will fluctuate the SCV flow to achieve the desired vacuum level.

Vacuum automation requires SeedStar™ 4HP monitoring. The system controls SCV flow based on the vacuum pressure sensor. The tractor must be a John Deere with Tractor Electronic Control Unit (TECU) 3 controller area network (CAN) system for this feature to be compatible. The vacuum automation feature will control all vacuum fans if they are on their own SCVs. More vacuum fans make the planter more valuable and easier to operate.

Vacuum automation is not compatible with Interim Tier 4 (IT4) 6R Series Tractors.

Row Runoff diagnostic test

The test functions from a mobile device

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.

Sensors for trench delivery system

Reflective seed sensor

Sensor on trench delivery system

On all ExactEmerge row-units, each cartridge will be 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 is able to 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.

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.

56.4-L (1.6 bu) hoppers available in base equipment

56.4-L (1.6-bu) hopper

Access to the meter under the hopper

The 1725NT utilizes a unique 56.4-L (1.6 bu) hopper that can be tilted and braced upwards to gain easy access to the meter for adjustments or cleanout.

This design also has a shutoff door to allow for meter access when seed is still in the hopper.

Compatibility

Two 56-V brushless electric motors

Improve productivity with two 56-V brushless electric motors

Two 56-V brushless electric motors provide ExactEmerge the upper hand over any other row-unit on the market. One motor controls the high-performance meter and the other powers the BrushBelt™ delivery system. Both feature a closed loop system ensuring they operate at the correct rpm.

The motor is controlled at a rate of 200 times per second and a decision is made every 5 milliseconds. The controller also keeps each motor operating at independent speeds of each other. The meter speed is determined by a combination of ground speed and desired population rate while the BrushBelt speed stays consistent with the forward ground speed of the planter in order to place the seed at the bottom of trench.

Brushless motors are maintenance free

Industry-proven 56-V brushless motors give confidence to the operator that the row-unit will perform in any condition. The advantage of 56-V over 24-V electric motors is a lower amperage draw.

Brushless motors are maintenance free and give the producer the most optimal solution to achieve the highest performance and the lowest amount of work to the planter.

Built-in RowCommand™ system

Manage seed output, reduce yield drag, and improve harvest capabilities are features built in to every ExactEmerge row-unit with electric motor shutoffs.

The electric drive version of RowCommand row-unit has the potential to get 2 to 8 percent reduction in seed usage from being able to control the meter and BrushBelt rather than a clutch disengaging and some seeds still falling down the seed tube.
