TRACTOR-IMPLEMENT CONTROL SYSTEM

A tractor includes an electronic tractor controller. A baler includes an electronic baler controller. The baler controller submits a halt signal to the tractor controller when a bale size is equal to or exceeds a first predetermined size. The baler controller generates a tractor halt signal in response to certain conditions of the baler system and the tractor controller preventing tractor motion in response to the halt signal. When the baler controller is generating the halt signal, tractor motion is enabled if the operator commands the tractor to move by manipulating the command device, and within a certain time period of said command being issued, the baler controller generates a tractor motion enabling signal in response a status of the baler system. When the baler controller is generating the halt signal, tractor motion is enabled if the operator moves the tractor command device in a special manner.
