Abstract
A system, apparatus and method for providing weight-based task-specific 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 calculate a present suspended weight and control maximum speed of the applicator for each task, per a predetermined schedule in response to the present suspended load of the applicator.
