Suspension system and method

摘要

Front and rear independent suspension mechanisms accommodating an increased range of motion to better absorb shock originating at the wheels of a riding mower to insulate the operator and reduce stress on the mower chassis and other mechanical components. The front suspension can include a front axle with pivot pockets allowing 360 degree rotation of pivots engaged within the pockets, thereby providing a greater range of absorption of shock entering the front axle at varying angles. The rear suspension can include a vertically pivoting transmission platform, providing for controlled vertical motion in the transmission while the transmission is powered by an engine by way of a belt assembly.

主权项

1. A suspension and drive assembly comprising:
a subframe including a first support and a second support, a pivoting mechanism pivotally coupled to a mower chassis and mounting the first support and the second support to a substantially horizontal chassis support; a belt-driven transaxle coupled to the subframe mounted between the first and second supports, the transaxle pivotable about the pivoting mechanism with respect to an engine mounted on the mower chassis outside of the subframe, the engine configured and arranged to drive the transaxle using a drive belt from a position outside of the subframe while the transaxle pivots with respect to the engine; and wherein the mower chassis supports at least one cutter deck configured and arranged to be driven by the engine.
