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. Two pivot point joints connect the blade housings and are located at approximately the same height as a plane containing the blades and the driven wheels include tires with a tread which is generally semi-circular in lateral cross-section with a center of the radii of the lowest part of the tread being located at approximately the average blade mowing height. Each blade housing is linked to a corresponding side frame by a mechanical linkage arm and a floatable connection that eliminate the need for rear caster wheels.
