  • Powered lawn mower hydraulic system
    Patent number: 3973379
    Abstract: A powered lawn mower hydraulic system for use with a reel type of mower. The system includes a hydraulic pump and a hydraulic motor and a hydraulic valve, all interconnected with hydraulic hoses or lines. The valve permits reversing of the direction of rotation of the motor which is driving the mower reel, and there is a hydraulic flow restrictor in the reversing line for limiting the speed of the motor, and thus the mower, in the reversing direction. Also, there is shown a relief valve for limiting the hydraulic pressure in the reversing mode, and there is also shown a relief valve for limiting the hydraulic pressure in the forward mode.
