  • Slope mower with improved blade housing floatation
    Patent number: 5161353
    Abstract: A mower vehicle includes a vehicle frame and single front and rear driven wheels. First and second blade housings are pivotally connected to each other along a longitudinal axis of the vehicle frame and are attached to first and second side frames, respectively. Each side frame is pivotally attached to the vehicle frame near the rear thereof with a hydraulically retractable and extendable cylinder assembly urging each side frame downward or upward in response to changes automatically sensed in the slope of the terrain. Ground engaging outrigger wheels attached to each side frame contact the terrain and the vehicle frame is thus maintained in a generally upright position.
