Pneumatic downforce provides more consistent downforce throughout the range of row-unit travel compared to heavy duty downforce springs. The amount of downforce applied is infinitely adjustable from 6.8 to 181.4 kg (15 to 400 lb). Manual control of pneumatic downforce provides simple adjustment of the whole planter from the electric compressor mounted on the front mast of the planter.Downforce is manually adjustable row-by-row. Adjustable heavy-duty downforce springs provide four settings to match downforce requirements to field conditions: 0 kg (0 lb), 56.7 kg (125 lb), 113.4 kg (250 lb), and 181.4 kg (400 lb).
