Abstract

See full text

An implement is coupled to and pulled by a tractor. The tractor includes ground engaging drive wheels driven by an engine, an operator movable speed command device, and a tractor controller having automatic and manual speed control modes. The implement has an implement control unit coupled to the tractor controller. The implement control unit transmits an implement speed request signal to the tractor controller. The tractor controller controls tractor motion in response to operation of the speed command device and the implement speed request signal. A system and method of controlling the tractor/implement combination includes generating an Operator Speed Limit value as a function of the speed command device, comparing the Operator Speed Limit value to the implement speed request signal, and automatically exiting the automatic speed control mode and enabling the manual speed control mode if the Operator Speed Limit remains greater than the implement speed request for the duration of a predetermined time period and if the Operator Speed Limit value has been increased.
