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 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.

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.

Overview

John Deere is now offering four new 1725C non-CCS models with three hopper options installed at the factory. The 1725C models with hoppers and electric drives include: 12R30, 12R36/38, 12R38/40, 16R30. The three row hopper options from the factory are 1.6 bu MaxEmerge™ 5e or ExactEmerge™*, 2.7bu ExactEmerge, and 3.0 MaxEmerge 5e.

*ExactEmerge not available on 76.2 cm (30 in.) units

Benefits

• Enables ExactEmerge or MaxEmerge 5e
• Enables the full agronomic suite (pneumatic row cleaners, individual row hydraulic downforce, pneumatic closing wheels)
• Optional ExactRate Liquid Fertilizer

 

Adding electric drives to the 1725C line brings improved agronomics to even more of our farmers. Adding electric drives to the non-CCS models opens up ExactEmerge. Additionally, peanut farmers and those who cannot use a central commodity system now have access to electric drives through MaxEmerge 5e. The addition of electric drives minimizes skips and doubles, increases spacing accuracy, and enables turn compensations.

The ExactRate fluid transfer system pairs planters seamlessly with the ExactRate tractor tanks. It provides an easy connection point to allow transfer from the ExactRate tractor tanks back to the planter tank. This enables up 3785 L (1000 gal.)* of capacity on the tractor tanks.

 

*NOTE: 3785 L (1000 gal.) assumes capacity on the integrated 8RX Tractor tanks.

 

• Factory installed
• Designed and tested by John Deere to ensure the lines do not pinch when folding
• Easily attaches to the ExactRate tractor tanks

 

If pairing with 8RX ExactRate tractor tanks, an additional valve can be ordered to improve priming performance. Part AA110692 can be ordered through Service Parts. All planters come with the brackets and U-bolts shown in the following image.

The 1725C stack-fold frame design can operate in both rigid-frame and flex-frame configurations. The frame has improved durability and Category 3/4N quick hitch compatibility. Color-coded hydraulic handles with an anti-slip grip for easy planter-to-tractor hook up was added. The 1725C utilizes a three-section frame that can flex up to 8 degrees up and 8 degrees down. The 1725C is not offered with markers.

 

The 1725C Stack-Fold Integral Planter is available in the following configurations: 12Row36, 12Row38, 12Row40 and 16Row30.

The 1725C 12Row36, 12Row38, and 12Row 40, and 16R30 are available without lift-assist wheels. This allows for increased maneuverability around tighter field conditions and bedded crops. Lift-assist wheels are an option for the 1725C 16Row30.

 

 

The vacuum is run through the planter frame. This cleaner frame design provides improved visibility when seated in the cab.

Optional wing downforce/gull wing is available on the 1725C. When traveling at speeds above 8.05 km/h (5 mph), row-unit downforce may be significant enough to overcome the frame’s wing weight, sacrificing ground contact and consistent depth. Hydraulic cylinders have been added to maintain force on the outer wings to keep desired depth. Operators can also pin the outer wings rigid with or without the wing downforce/gull wing option.

 

The same cylinders are used to enable the gull-wing feature on the 1725C. The gull wing flexes the outer wing up to 8 degrees upward, allowing for more vertical wing clearance.

An automatic hydraulic wing locking feature is available on the 1725C. Once the operator engages the frame-fold selective control valve (SCV), the hydraulics release the locking mechanism and the planter starts folding. This reduces trips up and down the tractor and provides for a much quicker folding and unfolding process.

Active pneumatic downforce is in base on the 1725C. This feature provides the proven downforce solution for growers to maintain consistent depths even at speeds up to 16.1 km/h (10 mph).

Several improvements have been made to the 1725C CCS tank and surrounding areas. The redesigned folding staircase is ergonomically friendly and stays out of the way of obstacles while planting. This change leads to the larger 1938-L (55-bu) CCS tank to help reduce fill times and let operators get the planting done quicker. The CCS tank has been raised 16.5-cm (6.5-in.) for added clearance of tank clean out, and the CCS blower has been relocated to lessen noise in the cab. The raised CCS tank and relocated blower also provide better visibility to the center row units.

 

CCS seed delivery adds productivity through:

• Increased seed capacity
• Bulk fill capability
• Easy, thorough cleanout

 

Filling the tanks is convenient due to a central filling location. The staircase and railing provide access to the filling platform between the tanks. Additionally, each tank has an adjustable bin-level sensor to alert the operator when it is time to fill.

 

A light-emitting diode (LED) fill light package is included on machines equipped with CCS. This feature includes two LED lights conveniently mounted on the railings of the machine. The lights are turned on and off with their own switch located at the bottom of the staircase.

 

If the seed-carrying vehicle requires hydraulic power to run the unloading system, the auxiliary hydraulic coupler option is available. These couplers are located at the bottom of the staircase and can be coupled under pressure. The system has a separate system filter that ensures the planter hydraulic system remains free of contaminants.

Seed delivery process

The 1938-L (55-bu) CCS tanks allow operators to spend less time filling and more time planting.

 

The CCS seed delivery process relies on a hydraulically driven fan to move seed from the CCS tanks to the row-unit hoppers. A flow control valve and gauge, located near the tank, allows for the proper tank pressure setting based on seed type. For normal operation, the CCS functions of fan and agitator control, as well as bin level sensing alerts, are controlled by status of the height switch. The CCS functions are enabled when the machine is lowered and disabled when the machine is raised. In addition, the CCS functions can be engaged for CCS hose cleanout using the switch on the back of the planter when oil flow is present. On models with software-based CCS control, CCS functions can be enabled or disabled through software interface in the cab as well as the switch on the back of the planter.

 

Air from the fan pressurizes the CCS tanks and delivers seed to the seed hoppers. Airflow enters the seed tanks through a nozzle in the manifold which pressurizes the tank. The air then picks up seed and moves it out the other end of the nozzle into seed delivery hoses. These hoses route the seed toward the hopper. A small amount of seed is traveling in the delivery hoses only when needed.

 

The hopper fills with seed until the delivery hose (discharge elbow) is covered. Once the opening is restricted, seed flow through the hose stops. Air flowing to the row-unit travels into the hopper and is the source of air for the vacuum system. This provides a much cleaner air source than previous meter designs. As the seed is picked up by the meter and planted, the seed pool shrinks until the end of the delivery hose is uncovered. At that time, the airflow and seed delivery resume and the seed pool in the hopper is replenished.

CCS seed cleanout

Seed cleanout is easy with a CCS planter. The CCS tank has been raised 16.5-cm (6.5-in.) for added clearance of tank clean out. When finished planting, any remaining seed can simply be removed via access doors at the bottom of the CCS tank.

 

CCS seed delivery hoses are then purged with air from the CCS fan, and the excess seed is pushed to the individual meters. The vacuum meter door is opened and seed is removed with the supplied catch pan.

Small seed CCS components

CCS seed delivery system increases planting productivity across the approved crops listed above. While highly effective delivering seed from the CCS tanks to the vacuum meters, small or light seeds require two additional components to aid in proper seed delivery.

 

Manifold nozzle covers (clips) should be installed to ensure seed is adequately picked up into the air stream for delivery to the row-unit. Mini-hopper discharge elbows should also be changed from the standard elbow (holes) to the small seed elbow (slotted openings) when planting sorghum (milo) and small cotton.

Individual Row Hydraulic Downforce (IRHD)

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.

Row-unit 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.

• 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)

Understanding Margin

Using Set Point downforce

Using Active Pneumatic downforce

SeedStar 4HP: Downforce

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.

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.

 

Active pneumatic downforce is available as factory installed or as an attachment for field conversion.

Set point row-unit downforce

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.

Features include:

• 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.

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

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.

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 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® 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.
