Claims

[Scope of utility model registration request]

(1) A lifting unloading valve G, a lowering check valve H1, a flow control valve E1, a flow control switching valve D, etc. are provided in a valve case V that is fixed to the side wall of the transmission case or hydraulic case of an agricultural tractor, and the valve case A pilot solenoid valve that electrically operates each of the above valves is attached to the side wall of the valve case.
A work equipment control device for an agricultural tractor, characterized in that a hydraulic external outlet is integrally provided in the controller.

(2) Scope of Utility Model Registration A signal from the traveling speed sensor 3 is transmitted to the controller 12 that controls the pilot solenoid valve described in claim 1, and the traveling speed change lever 5
A working machine control device for an agricultural tractor, characterized in that a lifting unload valve is automatically operated to the rising side when the tractor moves into reverse.
