ABSTRACT:
An improved riding mower is described of the type having propulsion means, a seat for the operator, and at least one cutting head which is hydraulically driven. The cutting head is controllable between an operating norm and a non-operating norm by means of a hydraulic valve having two moveable spools, and the cutting head is moveable between a cutting position and a transport position by means of a hydraulic cylinder. A solenoid is employed to control one of the moveable spools. A first electrical switch actuated by pressure in the seat, a second electrical switch actuated by the hydraulic cylinder, and a third electrical switch actuated by the second of said spools independently actuate the solenoid in order to stop operation of the cutting head when the operator is out of the seat, when the cutting head is not in cutting position, and when the operator does not desire cutting action.
