Abstract
A system, apparatus and method for providing task-specific ride-height and speed control in a self-propelled agricultural product applicator utilize a controllable ride-height trailing arm suspension system, including an extensible air strut and an angular position sensor, for independently joining each wheel to a frame of the applicator. An electronic control unit utilizes the angular positions detected by the sensors, in conjunction with a desired task input, to control the air struts in a manner providing a ride-height corresponding to the desired task input. The electronic control unit also controls maximum speed of the applicator for each task, per a predetermined schedule, or in response to a suspended load of the applicator.
