Claims

[Scope of utility model registration request]

Detecting that the connecting work device 3 has moved up and down a stroke proportional to 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 freely, based on the swing angle of the lift arm 4a. 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 relative to the traveling body 1. A rolling control mechanism 17 that performs an automatic rolling operation is provided to detect when the connecting device 3 has risen to a predetermined height, and in this detection state, the connecting device 3 is moved parallel to or almost parallel to the traveling machine body when viewed from the front and rear directions. The agricultural tractor is provided with a control mode changeover switch 22 that automatically switches the rolling control mechanism 17 to a parallel control mode, the changeover switch 22 being fixed,
The operating tool 24 for this switch 22 is
The agricultural tractor is configured to be elastically deformable in a direction away from the feedback mechanism 13, and is integrally and movably attached to the component 28 of the feedback mechanism 13.
