Abstract:
1. A method of controlling a combination of a tractor and an implement coupled to the tractor, the tractor including ground engaging drive wheels driven by an engine which is coupled to the drive wheels by a power transmission, an operator movable command device and tractor controller operable to control tractor motion in response to operation of the command device, the command device having neutral, park, center park, forward and reverse positions, the implement including a implement system for performing a function, and an implement controller coupled to the implement system and to the tractor controller, the method comprising: holding the tractor stationary while the implement controller requests zero tractor speed; when the implement controller requests a non-zero tractor speed, re-initiating forward motion of the tractor if the command device is moved from the center park position to the forward position; if the operator moves the command device from the center park position to the forward position before the implement controller requests a non-zero speed, preventing tractor motion until the command device is cycled again after the implement controller requests a non-zero speed; and enabling tractor motion before the implement controller is ready if the operator moves the command device to a position other than forward or center park.
