ABSTRACT:
A cushion suspension system for coupling an agricultural tool to a vehicle includes a flexible frame which permits vertical movement of the tool relative to the vehicle while maintaining the tool laterally fixed relative to the vehicle to prevent side-by-side oscillation. The flexible frame includes an air spring with an air filled bellows for providing vertical cushioning and a restoring force as the wheels of the vehicle encounter irregularities in the ground. Pressure within the air spring is adjustable to accommodate a range of agricultural tool sizes. The frame further includes a shock absorber for dampening vertical oscillation of the frame, with stops provided for limiting upward and downward displacement of the tool. The suspension system is particularly adapted for attaching an agricultural boom having a plurality of nozzles to a trailer-type sprayer.
