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 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.

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.

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. A high-rate option without openers is also offered from the factory. This system delivers:

• Up to 20 percent more accurate nutrient placement in a turn compared to a non-turn compensating system
• 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

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. 

Strainer

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.

Direct injection

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, but 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 can keep an eye on each row with flow detection integrated into the Gen 4 display. The system warns 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.

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.

Rate Controller

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.

Liquid tank mounted on a 24-row 1775NT Planter

John Deere factory-installed liquid tanks offer a convenient way to carry fluid on the planter frame. Styling cues match the CCS™ system tanks, and all brackets and mountings are 100 percent factory installed.

• Factory installed
• Up to 2271 L (600 gal.) of fluid capacity
• Clear sight tube to check fluid level
• Air bleed and overflow protection

Liquid Tank mounted to a 24-row 1775NT Planter

LED light on stairs to the CCS™ system platform

As planting windows get tighter, many growers are working longer hours to get the seed in the ground. With the planter LED lighting package, John Deere delivers better visibility when planting a night.

• Four additional LED lights
• Improves visibility when planting at night
• Illuminates row-units when servicing at night
• Turns on when tractor lights are engaged

1795 24Row15 and 1795 32Row15 are two even split row planter models.

Even-row planter configurations are designed to plant no-till soybeans between standing corn stalks. The extra row, along with a two-position hitch, makes it possible to place two soybean rows between the old corn rows, and the guess rows match up across the field. This gives better depth consistency since gauge wheels aren’t running on top of standing corn stalks.

• Increase productivity by 7 percent when planting with all rows.
• Effective working width is the same when planting corn or soybeans.
• By shifting the hitch of the tractor, producers can split last year’s corn rows with two soybean rows while keeping the tractor’s tires between the corn rows.
• Guess rows match up when planting parallel with last year’s rows.

The extra row-unit is placed at the left side of the planter on the rear rank of row units. It does not increase road transportation width or height.

When planting on 38.1-cm (15-in.) spacing, the working width is increased by 38.1-cm (15-in.), or 3 to 4 percent. To change over to 38.1-cm (15-in.) planting on an even-rowed planter, the two-point hitch needs to be offset. While planting on 76.2-cm (30-in.) spacing, the attaching bolt is in the center position. When changing to 38.1-cm (15-in.) spacing, the planter is offset 19-cm (7.5-in.) to the side. The markers would need to be adjusted.

The offset hitch puts a slightly higher draft load on the right side of the tractor than the left side. For wheeled tractor applications, the operator is actively steering the tractor and a different draft load isn’t obvious nor is the steering cumbersome. On track tractors, where the steering wheel returns to a neutral position, it is obvious that the draft of the planter isn’t centered behind the tractor.

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 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.

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. For model year 2020 and newer MaxEmerge 5e planters, mobile row-unit runoff is included in base equipment. For planters not equipped from the factory, mobile row-unit runoff can be added with attachment AA93169. A mobile row-unit runoff and Easy Fold package can be added with attachment AA97849 (only available with 1775NT and 1795 Planters with a 2-point hitch and model year 2019 and newer DB Planters with Gen 4 based frame folding).

NOTE: Mobile runoff utilizes the EquipmentPlus app available on select iPad® tablets, iPhone® smartphones, and Android™ devices.

Individual Row Hydraulic Downforce (IRHD)

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. 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

Pneumatic valve

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

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.

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)

Margin video references:

Understanding Margin

Using Set Point downforce

Using Active Pneumatic downforce

SeedStar 4HP: Downforce

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.

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.

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

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.

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.

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.

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).
