STRETCH YOUR PRODUCTIVITY
If youre looking for a productive, all-purpose planter that can help you make the most of your narrow planting window, ask your dealer about the incredible DB Series Planters from John Deere. These acre-hungry machines will help you finish faster.

The DB Planters are available in ten configurations, with widths from 44 to 120 feet, for 20-inch, 22-inch and 30-inch row markets. Theres also a split-row model. All have the features and options you need for true planting efficiency and versatility. Our John Deere row-units and vacuum seed meters lead the industry in accuracy, adjustability and planting speed.

A range of seed-carrying capacities increases your flexibility and reduces refill stops. Plus you can add the new Central Insecticide System and shave hours off your refilling time. The Central Insecticide System is a revolutionary closed handling system thats designed to give you both effective corn rootworm control and exceptional planter productivity. And reliability? Dont worry these planters and their frames are among the toughest around, with plenty of 7x7 steel framing to tie everything together.

With long planters like these, tight turns could give you some uneasiness. But fear not. Thanks to optional steerable axles, the DB Series can cut corners with no trouble at all so you can get in and out of the field worry-free. Just hook the axles up to an independent hydraulic SCV on the tractor and youre ready to go. (Not available on DB60 models)

An easy-to-use control box lets you fold and unfold the DB Planter from the tractor cab. Can 44- to 120-foot planters really fold to a manageable transport size? You bet! In fact, the front-fold design of the DB Series Planters keeps transport widths between 15- and 17.6-feet. Lengths vary, but all are less than 62 feet. Ample underframe clearance (22 to 26 inches) during transport makes it easy to clear obstacles.

Large walking wing wheels keep the DB Planters floating on top of the ground, while wheel spacing improves residue flow. Wing cylinders have locking brackets for safety.

FRAME WEIGHT DISTRIBUTION

As planters get larger and more customizable, there is more weight being carried by the center mainframe. This presents the possibility that weight may not be distributed evenly along the width of the planter frame during planting in certain circumstances. Some studies have shown there could be a potential yield loss of 70.5 L (2 bu) per acre in certain soil conditions from unequal weight distribution with more weight being on the center of the planter. The option has been added to have hydraulic cylinders mounted onto the frame of the planter that redistribute weight from the center of the planter to the rest of the tool bar.

The frame weight distribution can be enabled or disabled on the Gen 4 4600 CommandCenter Display or 4640 Universal Display with SeedStar 4HP on MaxEmerge 5e or ExactEmerge equipped planters. MaxEmerge 5 equipped planters utilize an on/off switch by the valve block to enable and disable the system.

The system utilizes the tractors power beyond feature with load sense. Frame weight distribution is activated by the height switch, providing equal weight distribution at all times. In the scenario where a planter is equipped with frame weight distribution and onboard power generation for electric drives, there will be an orifice that directs hydraulic flow to fulfill the power generation requirement first and then provide oil to frame weight distribution.

Frame weight distribution is manually adjusted from a valve block below the CCS tank. The system does not have active adjustment capabilities. When the planter is raised on headland turns, the system maintains pressure to the outside wings for a period of time to keep the system engaged to make the turn and reduce center frame tire weight on headlands.

Unlike the three-section frame models, the DB90 54Row20 has five-section frame weight distribution. This means the inner wings and outer wings are adjusted independently. Five-section frame weight distribution is still manually adjusted from two separate valve blocks under the CCS tank; one controls the inner wing down pressure and the other controls the outer wing down pressure.



Available on the following models:1775NT 24Row30, DB66 36Row22, DB90 54Row20, and all DB60Planters.

SeedStar 3 HP conversion to SeedStar 4HP with mobile row-unit runoff aftermarket for field conversion kits

Growers who are currently running model year 2017 planters, model year 2017 and newer Precision Upgrades, or model year 2017 and newer custom-built planters with the SeedStar 3 HP monitoring system can upgrade to the SeedStar 4HP monitoring system with mobile row-unit runoff. The attachment part, AA100382, is software only. The Gen 4 display software version will need to be 19-1 or newer and will require planter apps. Follow the mobile runoff ordering and software push guide below for ordering and installation. Retrofitted planters and custom-built planters will also require the John Deere Connect Mobile kit, 0048PC, from the Precision Ag Technology Price Pages and wiring harness AA83662 to enable the mobile row-unit runoff feature. Please reference Parts Advisor and DTAC Solution 105181 for model-specific mounting brackets. SeedStar 4HP requires the Gen 4 4600 CommandCenter v2 display or 4640 Universal Display.

In the SeedStar application, many adjustments can be made, including manually activating section control. SeedStar 4HP allows up to 48 individual row sections. There are several setup features such as crop, seed disk, number of rows being planted, population alarms, and limits. Seed rates can be modified, electric power generation (EPG) can be turned on or off, vacuum can be adjusted, and the fill and purge functions can be used from the SeedStar application. Frame control, as well as diagnostics and calibrations, can be accessed at the bottom of the screen.

Reduce set-up time between changing crops or field conditions by recalling saved settings used previously with Settings Manager, included with every SeedStar 4HP system. This feature allows saving and recalling planter and tractor settings for optimum performance in different conditions.

Settings Manager can be used to save all the adjustment and inputs associated to a particular crop or condition. An example would be to store all population rates, downforce pressure, row cleaner adjustments, and closing wheel settings for planting corn and storing a separate, unique set of adjustments for soybeans. In addition, Settings Manager stores tractor settings such as selective control valve (SCV) flow and detents, infinitely variable transmission (IVT) settings, eco modes, and more.

Custom rates allow for individual row population control and row-by-row documentation where up to six different rates can be assigned across an up to 48-row planter. This allows growers interested in planting seed corn with ExactEmerge or MaxEmerge 5e the capability to assign specific populations to male and female rows for planting. This feature can also be used to create tram lines or other applications where custom rates by row are needed.

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 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 Deeres 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.

EASILY CARRY FLUID ON THE PLANTER WITH LIQUID TANKS

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.

DB FERTILIZER OPTIONS

Option code 2625 Liquid fertilizer with row-unit mounted in-furrow applicator:

This option contains a ground driven pump, plumbing to a manifold, and routing to each row-unit. The in-furrow applicator places fertilizer after the seed and before the closing wheels.
The DB60 24Row Split 47 Planter and DB60 24Row Split 48 Planter applies fertilizer on 76.2-cm (30-in.) row spacing only.

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 Equipment Mobile 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.

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).

DOWNFORCE SYSTEM OPTIONS

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 machines 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.

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.

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.

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.
Pneumatic air bags with 9.5-mm (3/8-in.) air line inlets that have greater durability.
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.

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).

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 overpopulated while the outside rows are underpopulated.

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 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.

ROW CLEANER OPTIONS TO MEET RESIDUE MANAGEMENT NEEDS

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 Deere 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 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 5e row-units with long parallel arms.
