A system, apparatus and method for providing task-specific ride-height control in a self-propelled agricultural product applicator utilize a controllable ride-height trailing arm suspension system for independently joining each wheel to a frame of the applicator. Each trailing arm suspension system includes upper and lower suspension arms, an extensible air strut, and an angular position sensor operatively interconnected to one another and disposed between a rolling axis of the ground engaging wheel independently supported by that suspension system and a point of attachment of the suspension system to the frame, such that the position sensor detects a relative angular position between the upper and lower suspension arms at a present extension of the air strut. 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.
