The movement of the connecting work device 3 is detected based on the swing angle of the lift arm 4a, which is an example of the operation amount of the operating tool 14 of the vertically swinging lift arm 4a that connects the work device 3 so as to be able to move up and down. In this detection state, a mechanical feedback mechanism 13 is provided to automatically return the control valve 12 of the lift arm 4a to the neutral position, and the connecting device 3 is moved horizontally or almost horizontally to the traveling body 1. A rolling control mechanism 17 is provided for automatic rolling operation, which detects when the coupling device 3 has risen to a predetermined height, and in this detection state, controls the coupling device 3 in front and rear directions with respect to the traveling machine body. to be parallel or nearly parallel. 7. Control mode changeover switch 22 for automatically switching the rolling control mechanism 17 to a control mode.
The agricultural tractor is equipped with the changeover switch 22 on a member 25 constituting the feedback mechanism 13.
The switch 22 is located below the base end of the lift arm 4a and in front of the rear end of the traveling body 1. tractor.゛
