  • Slope mower
    Patent number: 5203149
    Abstract: A slope mower which can tilt a tractor body upslope about pivot points on the front and rear axles during operations on sloping terrain. The slope mower has a novel all geared powered belly mower and also has a novel mower lifting system. The slope mower also has a novel three point hitch attached to the tractor axle which allows for attaching utility devices but does not interfere with the tilting mechanism. The slope mower also has the ability to transfer engine power to the rear of the slope mower. Upon removal of the belly mower, a power take off is extended through both the front axle pivot point and the rear axle pivot point. This allows engine power to be transferred to a rear utility device without affecting the tilting ability of the slope mower. Reinforced caster wheels are attached to the belly mower.
