Pneumatic downforce systemPneumatic downforce provides convenient, simple adjustment of downforce for the whole planter from one location. The amount of downforce applied is infinitely adjustable from 0 kg to 181.4 kg (0 lb to 400 lb). Pneumatic downforce provides more consistent downforce throughout the range of row-unit travel than mechanical spring downforce systems.
Such improvements to the pneumatic downforce system enable faster and more precise control of row-unit downforce while planting. SYSTEM FEATURES 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. 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. From the factory, integral planter models with pneumatic downforce will have an improved air compressor assembly with an in-cab mounting bracket, except the 1725 16Row and 1725 Central Commodity System (CCS™) Twin-Row Planters which will have the air compressor assembly mounted on the planter frame. For drawn planter models, the 1755, 1765, 1765NT, 1775 Front-Fold, and 1785 Drawn Planters will have the air compressor assembly installed either on the outer hitch or wing frame members when the pneumatic downforce system is installed. |
Vacuum systemVACUUM BLOWER ASSEMBLY Vacuum is created by a hydraulically driven vacuum blower assembly mounted on the planter frame. The vacuum blower requires a tractor with a closed-center hydraulic system and a separate selective control valve (SCV). For tractors with open-center hydraulic system, a vacuum 540- or 1000-rpm power take-off (PTO)-driven hydraulic pump system is available. PTO pumps offered from the factory are limited to 15-row applications or less. Different vacuum levels are required depending on the crop being planted. A hydraulic control valve lets the operator regulate vacuum blower speed, changing the vacuum level. On late-model John Deere tractors, vacuum levels are set from the tractor seat using the SCV controls. The control valve is not needed in those applications. At full flow, the system flows up to 18.9 L/min (5 gpm) per motor. Convenient vacuum gauges located on the planter hitch give a visual indication of the vacuum level. When using a SeedStar™ monitor, the vacuum level can be displayed on the monitor. Consult the vacuum metering seed charts in the operator's manual for initial vacuum setting recommendations.

VACUUM METER CASE DRAIN All planters with vacuum metering systems have case drain motors on the vacuum blowers. Case drain lines will have a flush-face case drain coupler on the planter and will require a corresponding flush-face case drain coupler on the tractor. The flush-face coupler simplifies implement attachment by allowing operators to easily identify the case drain. The unique hose tip is unable to connect to another coupler on the tractor, ensuring the correct setup. It is important to connect this case drain hose to prevent the continuous and complete draining of hydraulic fluid due to the relief feature that opens the coupler when the pressure reaches 10 psi. This relief feature is designed to protect the motor shaft seal if for any reason the case drain hose was not connected to the tractor. The flush-face hose tips have less back pressure than ISO case drain tips, and the flat surface makes these couplers easy to clean, providing less chance for contamination. The case drain line is also used with all Central Commodity System (CCS™) fan motors. |
Advance with MaxEmerge™ 5 advantagesMaxEmerge 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. 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. 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. 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:
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 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. VACUUM METER SEED DISKS The ProMax 40 Flat Disk is a flat-disk planting solution field-proven to work since 1991. 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. |
Ground-contact drive wheelThe ground-engaging drive wheel system is a simple, proven, and reliable way to power the seed transmission(s). As the drive wheel turns, power is transmitted through a single-pitch drive chain to the jack shaft, on to the seed transmission, and out to the seed meters. Slip-clutch protected, spring-loaded idlers and steel sprockets provide a smooth-operating, dependable chain drive. The ground-contact drive system has the following common features:
1705, 1715, AND 1725 PLANTERS 1705, 1715, and 1725 Planters (except 1725 16Row30) are driven from one rear-mounted, ground-contact wheel. 1735 PLANTER DRIVE A 1735 Planter is driven by one front-mounted ground-contact wheel. 1755 PLANTER DRIVE Using ground-contact drive wheels much like the integral planters, the 1755 Drawn Planter utilizes two drive wheels. |

Seed variable-rate drive provides the ultimate planting productivitySeed variable-rate drive provides the ultimate planting productivity by utilizing one, two, or three hydraulic motors (varies by model) 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 the prescribed map. Variable-rate drive offers the following advantages over common, ground, or contact-tire drive systems:
Single- or dual-motor systems for variable-rate drives are available for all John Deere planters except the 1785 Rigid Frame. Variable-rate drive is available as a factory-installed option for all applicable planter models. NOTE: Peanut seed meter disks require the variable-drive transmission. |
