Pneumatic downforce systems are available as a factory-installed option on all planters and as a field conversion bundle for all MaxEmerge XP, MaxEmerge Plus, and MaxEmerge 2 planters. Downforce is infinitely variable from 0 lb to 400 lb. A gauge provides a reading as to how much down force the system is providing. The downforce is constant at all times during operation. Each row-unit has a single air bag located between the parallel arms. The air bag is hooked in parallel so that air can be added or released from all rows at once from one location. Split-row planters have the corn row-units and the soybean rows plumbed separately so the pressure can be removed from the bean rows when planting corn. MaxEmerge 2 row-units with long parallel arms MUST have the arms changed to current production parallel arms. This will provide the correct hole pattern for pneumatic downforce. Refer to the attachment description to order the appropriate bundle for the frame size. NOTE: Row units with long parallel arms require a spacer block (A54544) if not so equipped (Service Parts). A small compressor, located either in the tractor cab or on the frame, pumps up the system. 1700, 1710, 1720, 1730, 1770NT CCSTM and 1790 Planters ordered with pneumatic downforce from the factory have in-cab mounting as base equipment. Valves located on the compressor allow bleed-off of the system. Interplant rows are shut off entirely when those rows are locked up. Field conversion bundles have been established for pneumatic downforce systems. With the bundle structure, order the individual components for a pneumatic downforce system. There are individual bundles for the air compressor, the row-unit downforce assembly, and a hose kit. Each planter will require one air-compressor bundle, a number of row-unit down-force assemblies equal to the number of rows on the planter, and a hose kit for each 12 rows being equipped with pneumatic downforce. There are four different row-unit downforce assembly bundles. The selection of the row-unit down-force assemblies will be based on the type of meter drive, chain or Pro-ShaftTM, and the type of parallel arms being utilized, regular or long, on the row units.
