ABSTRACT:
Implement draft control devices are typically utilized on agricultural vehicles such as tractors and on other earthworking type vehicles. Advantageously, such control systems should respond quickly to changing soil conditions, while remaining stable so that the hitch and implement systems do not oscillate or are not changed in a rapid or erratic fashion. The instant embodiment of a draft control system includes a control system that receives hitch position control signals and engine acceleration signals, and controllably modifies the hitch position control signals in response to the rate of acceleration and deceleration of the engine. By utilizing engine acceleration and deceleration rates as opposed to mere changes in engine speed, the system is able to respond quickly to needed changes in implement depth while remaining stable during operation.
