Advance with MaxEmerge™ 5 advantages

MaxEmerge 5 bundles the best of MaxEmerge XP and Pro-Series™ XP row-units to give you a unique planter solution. With more options and configurations, you’ll get difference-making versatility that easily adapts to your ag management plan.

It starts with optimal seed population that drives yield potential. An improved double eliminated helps achieve your desired population with a ride range of crop sizes. Improved side-hill performance of up to ¼ degree ensures you receive the full value of each seed when planting on terraces or rolling terrain. The vacuum air source from the Central Commodity System (CCS™) tank in the meter provides a debris-free environment for increased meter efficiency.

MaxEmerge 5 with 56-L (1.6-bu) hopper plus insecticide

MaxEmerge 5 with mini-hopper on CCS™ machines only

The MaxEmerge family of row-units have never seen a more versatile and efficient design until the MaxEmerge 5. The 5-family row-units improve productivity, increase uptime and lower the cost of ownership like never before.

The MaxEmerge 5 row-unit was designed for improved performance and serviceability.

Easily access the meter

Serviceability and changing crops have always been a focus of downtime and potential seed loss. The MaxEmerge 5 meter (shown on the right) is accessible without having to remove the box. The design allows large hoppers to be cleaned out the same as mini-hoppers, simply by opening the meter dome and catching the seed as it falls out.

MaxEmerge 5 vacuum seed meter

The vacuum meter system gently pulls and holds individual seeds to the holes of the seed disk for population control and spacing accuracy, equaling better crop stands and profit. Vacuum seed meters can plant a wide variety of crops and seed types by simply changing seed disks and adjusting vacuum level. Vacuum seed meters are available for planters with MaxEmerge 5 row-units.

Additional features of the vacuum seed meter include:

One moving component (the seed metering disk) for minimum maintenance requirements
Meter located at each row-unit for accurate seed delivery
Good hopper seed flow characteristics for longer operating time per hopper fill
Low airflow in meter so seed treatments are not removed

MaxEmerge 5 seed pool

The MaxEmerge 5 meter shape has also been redesigned for better seed flow. The mini-hopper design allows the planter to successfully operate on side hills up to 14 degrees.

Vacuum meter hub and latching handle

MaxEmerge 5 vacuum meter with disk

Both the MaxEmerge 5 vacuum meters are equipped with a heavy-duty hub spring and disk latching handle. The spring ensures the seed disk stays properly positioned when operating flat-style seed disks and higher vacuum levels. Proper seed disk positioning means repeatable seed singulation, time after time. The disk-latching handle is designed for easy operation and effortless seed disk changeover. The hub is also machined to tight tolerances to further ensure alignment of metering components.

Operating characteristics of vacuum seed meter

Operating speed with seed tube technology

The vacuum seed meter can operate at faster planting speeds than mechanical meters. However, planting accuracy will be influenced by seedbed conditions and the operating characteristics of the seed meter. Rough seedbeds and fast planting speeds (above 8.9 km/h [5.5 mph]) typically deteriorate seed placement accuracies when using seed tube technology.

The chart illustrates the effect operating speed has on population when using the vacuum meter. The operating band (color area) illustrates how the vacuum meter performs in relation to the desired population (indicated by horizontal line). The width of the band is due to various sizes and shapes of seeds and planting rate variations.

When operating on slopes above 15 degrees, increased or decreased population may result. To minimize this effect, reduce speed and consider using a flat style seed disk with increased vacuum level.

Vacuum meter seed disks

The ProMax 40 Flat Disk is a flat-disk planting solution field-proven to work since 1991.

ProMax 40 Flat Disc

The design of the ProMax 40 Flat Disk position allows seed to be released from the optimum position above the seed tube. The flush-face seed tube allows the seed to drop uninterrupted through the tube.

The ProMax 40 Flat Disk utilizes flat holes and a higher vacuum level to ensure every hole is populated with a seed. A double eliminator gently removes multiple seeds at each hole for precise population control. A knockout wheel makes certain that each hole is clear of any debris after the seed is released from the disk.

Flat-style and cell seed disks shown

The unique cell disk design allows planting a variety of seed sizes without any additional parts or individual meter adjustments. Another advantage of cell-type seed disks is the lower vacuum requirement compared to flat-style seed disks. Lower vacuum levels mean less hydraulic demand from the tractor. Most planting conditions call for a flat disk, if you are limited in hydraulic capacity, cell disks are recommended.

Double eliminator

Flat seed disc and double eliminator

For difficult to singulate seeds, a flat seed disk and double eliminator is a viable alternative to traditional cell-type seed disks. By design, a flat seed disk requires higher levels of vacuum than a cell-type disk because there is no pocket or cell to hold the seed. The higher vacuum level will pull more than one seed to the holes in the seed disk. The double eliminator is set to cover a portion of the hole in the seed disk and is the mechanism to knock multiple seeds away as the disk rotates.

Double eliminators are required with flat-type seed disks only and should not be used with cell-type seed disks. The knockout wheel is also recommended in conjunction with the double eliminator and flat seed disk to ensure seed is ejected from the disk.

Flat and celled type seed metering disks are available to allow planting a wide variety of seed types.

Corn (field, popcorn, or sweet corn)

Mini-hopper row-units, which are used only with the CCS, are compatible only with crops that the CCS is approved to plant.

Corn
Popcorn
Sweet corn
Soybeans
Sunflowers
Sorghum
Cotton

NOTE: Due to small seed size and low planting populations, sugar beets can be planted with mini-hopper style meters by adding hopper extensions and not using the CCS tank. These hopper extensions can also be used for planting test plots.

Hopper shutoff

Also, to help with meter access of 56-L and 106-L (1.6-bu and 3-bu) hoppers the hopper shutoff feature was added. With the shutoff engaged, the meter cover can be opened without first having to remove all the seeds from the hopper. Lever down, the seed flow is on, lever horizontal and the seed flow is off.

MaxEmerge 5 mini-hopper

There are significant changes to the MaxEmerge 5 mini-hopper. One update is the straight feed from the CCS hose to the mini-hopper to ensure a continuous free flow of seeds. This design change reduces the potential for plugging issues with larger seed size and the use of seed treatments. By drawing air from the CCS tank, the vacuum source is cleaner, preventing meter debris buildup.

Ductile iron-cast shank

Ductile iron casting is a unique high-tech process that produces a single-piece row-unit shank this enables alignment from the seed trench to the closing wheel.

The row-unit head is also designed using the ductile iron-casting process. The row-unit head provides the mating joints between the row-unit parallel arms and the row-unit shank. It is also the upper attaching point for the seed meter and seed hopper.

Ductile iron casting of the row-unit shank and head assembly provides a row-unit that is 25 percent stronger than other competitive welded row-units.

Tru-Vee opener blade

One of the trademark capabilities of John Deere planters has always been the ability of the Tru-Vee openers to provide an ideal seed furrow.

The thickness of the Tru-Vee opener blade is 3.5 mm (0.14 in.) this blade thickness will provide extended wear life.

The MaxEmerge 5 row-unit also provides better Tru-Vee opener bearings for longer life. The double-row ball bearing provides up to three times the wear life as the single-row bearing.

Depth adjustment T-handle

John Deere planters provide consistent seed depth control in all field conditions. Depth control is a function of the Tru-Vee openers, the downforce system, and the gauge wheel assembly.

The gauge wheel itself is made of durable nylon composition with a concave profile. This profile gently firms the sides of the seed furrow, ensuring a well-defined trench. The shape reduces rocks and residue being picked up and thrown onto the drive chains and row-units, and helps to prevent rooster tailing of soil.

The bolt-through design utilizes an open bearing in the gauge wheel that allows an attaching bolt to pass through the wheel to the threaded hole in the gauge wheel arm. This simple bolt-through design provides for a positive attachment of the gauge wheel to the gauge wheel arm and allows quick removal of the gauge wheel for service.

Adjustability of the row-unit is critical to good performance. More available downforce options than any row unit in the industry

Adjustable heavy-duty downforce, four settings, 0 kg (0 lb), 57 kg (125 lb), 113 kg (250 lb), and 181 kg (400 lb) of downforce
Pneumatic downforce, infinitely variable from 0 to 181 kg (0 to 400 lb) of downforce
Active pneumatic downforce adjusts automatically for changing ground conditions from 0 to 181 kg (0 to 400 lb) of downforce

Rubber tire closing system

Cast wheel closing system

Rubber tire closing systems are used for most conventional, minimum-till, and no-till planting conditions. The spacing between the wheels is adjustable so the closing system can meet the needs of those who want to plant small seeds at shallow depths.

The wheels can also be staggered fore and aft to enhance residue flow. Four levels of spring force are available and are easily set with the integrated T-handle adjustment. A lower force spring can be obtained from parts, if a lower amount of force is required.

Additional closing wheel options include:

Cast closing wheels for tough-to-close conditions
Disk closing, for shallow planting depths
Closing wheel frame less wheels for growers desiring to use aftermarket closing wheels

Increase overall productivity with Central Commodity System (CCS™) seed delivery system

CCS

CCS seed delivery adds productivity through:

Increased seed capacity
Bulk fill capability
Easy, thorough cleanout

Crops that can be planted with the CCS System include corn, sweet corn, popcorn, cotton, sunflowers, sugar beets, soybeans, and sorghum (milo).

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

CCS is about reducing the time spent filling the planter with seed while maximizing the time spent planting. CCS for planters is a form of seed handling and delivery. The row-units perform the final task of seed metering and placement.

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 tank scales for DB Planter models

The CCS tank scales for DB models are a stand-alone system from Digi-Star. Load cells are installed at the factory and can be ordered for CCS equipped machines.

There are three load cells: two at the rear of the CCS cradle and one at the front. They weigh both tanks as one; individual tank weights cannot be determined.

The load cells and display are made by Digi-Star. They are not on the controller area network (CAN) bus system so they are not integrated into SeedStar™ software in any way. The monitor is sold separately through Digi-Star.

CCS seed cleanout

Seed cleanout could is easy with a CCS planter. 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

Manifold nozzle and nozzle with cover installed

Straight seed inlet installed in mini-hopper

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.

Seed variable-rate drive

Variable-rate drive system

The seed variable-rate drive provides the ultimate planting productivity by utilizing three hydraulic motors to turn the seeding drive shaft. Hydraulic control of the seeding drive allows for on-the-go seeding rate changes right from the display mounted inside the tractor cab. Combine this seeding flexibility with the map-based planting option and seeding rates adjust automatically based on a prescription map.

Seed variable-rate drive requires the SeedStar™ monitoring system and a speed input signal. Either tractor or planter radar may be used or a global positioning system (GPS) speed signal. Radar speed input signal is recommended. Planter radar is ordered separately.

Seed variable-rate drive offers the following advantages:

Rate changes are almost instantaneous – no ramp up or ramp down of the system as in some competitive systems
Permits the operator to match seed population based on different soil types or irrigation practices
John Deere design provides added operator safety by eliminating any possible drive creep found in some competitive variable-rate drive systems

Three-width drive disconnect

Three-width drive disconnect control

Three-width drive disconnect feature is activated by three individual console mounted switches (control box) conveniently located in the tractor cab. The function easily shuts off the planter row-unit seed meters by one-, two- or three-drive segments independently.

Lift-assist wheel steering

Hydraulic steering for chassis lift system

Hydraulic steering cylinder

Position sensor

The hydraulic steering assists the operator while backing into the next pass. The implement wheels are steered in the opposite direction of the tractor steering wheels when in reverse. The system is calibrated to steer the lift-assist wheels to the ideal steering angle when turning in reverse and guides the planter from a position sensor mounted to the tractor's front axle.

This steering system prevents the lift-assist wheels from casting or spinning around when the direction is changed from forward to reserve. This saves disruption to beds or soil. The hydraulic steering also provides resistance to lift-assist wheels, eliminating vibrations from the wheels while traveling forward, and is most beneficial during transport.

Less hydraulic steering for chassis lift system

Less hydraulic steering

Less lift-assist wheel steering is available to producers who do not need to guide the lift-assist wheels in reverse. This eliminates the need for the position sensor mounted the tractor’s front axle. The less hydraulic steering option does not provide resistance to vibrations from the lift-assist wheels during transport and allows the wheels to caster or spin around during direction changes.
