Margin is essentially a reading of how much weight the gauge wheels are carrying. The SeedStar XP monitor provides the operator downforce margin readings for the three rows equipped with a gauge wheel load sensor.The system has a valve stem which allows filling with shop air as a backup if the compressor stops working.Downforce is easily adjusted from the display.Integrated downforce comes with an electric compressor and storage tank mounted on the rear of the planter for quick downforce adjustments.

The amount of downforce is infinitely adjustable from 6.8 to 181.4 kg (15 to 400 lb). Operators can see gauge wheel margin readings on three rows of the planter and either add or remove air from the pneumatic system to maintain a good level of load (margin) on the gauge wheels. Integrated control of pneumatic downforce provides simple adjustment of the whole planter conveniently from the tractor cab with the SeedStar™ XP monitoring system.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).
