suspension system, self-propelled agricultural product applicator and method for controlling the height of a frame of a self-propelled agricultural product applicator above a ground surface

摘要

It is a system, apparatus and method for controlling the height of a self-propelled high altitude farmland applicator above a ground surface using a rear rocker suspension system including an air damper. to connect applicator ground contact wheels to the applicator frame. the rear arm suspension system includes an upper suspension arm attached to the frame, a lower suspension arm that provides unique support for a ground hitch wheel attached to the lower arm, and the extendable air damper is interconnected between the arms. lower and upper. The height of the applicator above the ground surface is controlled by regulating a pressurized air flow to the air damper to thereby control the extent of the air damper.
