Abstract: Some embodiments of the invention provide a transaxle drive system for ride-on equipment. The transaxle drive system can include a frame supporting at least one power source and at least two subframes, the at least one power source including at least one drive pulley. The system can also include transaxle assemblies driven by at least a portion of at least one belt from the at least one drive pulley. The transaxle assemblies can include a first transaxle assembly supported by a subframe, the first transaxle assembly coupled to the at least one drive pulley with at least one belt, and a second transaxle assembly supported by another subframe, the second transaxle assembly coupled by at least one belt to the at least one drive pulley. The transaxle assemblies can be independently pivoted with respect to each other, the frame, and the power source.

Abstract: Some embodiments include a transaxle drive system for ride-on equipment with a plurality of transaxle assemblies supported by a suspended subframe, and a frame supported on a pair of front wheels at one end that is coupled to and pivotably suspends the subframe. Some embodiments include a power source with a drive pulley supported by the frame at an opposite end. Some embodiments include a belt coupling the drive pulley to a driven pulley of the transaxle assemblies. In some embodiments, the plurality of transaxle assemblies can be driven from the drive pulley by at least a portion of the belt. Further, in some embodiments, the plurality of transaxle assemblies include a first and second transaxle assembly each coupled to a separate rear wheel. The first and second transaxle assemblies are suspended from the subframe, and can be pivoted together about the frame, and the at least one drive pulley.

Abstract: A zero turn mower may include a frame having a front portion, a rear portion and opposing side portions, a pair of front wheels located near the front portion of the frame, a pair of rear wheels located near the rear portion of the frame, wherein the engine is supported by the frame in between the pair of rear wheels near the rear portion of the frame, a seat supported by the frame, a cutter deck assembly having at least one cutting blade to cut grass, wherein the cutter deck assembly is located between the pair of front wheels and the pair of rear wheels, a utility bed supported by the frame having an imperforate floor and an air intake through which air is drawn to cool the engine.

Abstract: 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.

Abstract: Some embodiments of the invention provide a suspension system coupled to a main frame of ride-on equipment including a subframe coupled to the main frame with a pivot including a pivot axis. Some embodiments include a transaxle assembly supported on the subframe coupled to a drive wheel, and a power source supported on the main frame coupled to the transaxle assembly. A rider can control the transaxle assembly with a compensated control linkage assembly that can compensate for movement of the subframe. Some embodiments include driven pulleys, idler pulleys and backside idler pulleys supported by the subframe coupled to the power source not supported by the subframe. In some embodiments, the pivot axis resides between the power source and the transaxle assembly. In some embodiments, the drive wheel can be driven by an electric motor supported by the subframe and the power source can be a battery.

Abstract: A mower comprises a utility bed that extends at least partially over an air intake screen of an engine.

Abstract: A machine includes a prime mover having a power take-off, a chassis configured to support at least an operator and the prime mover, a subframe pivotally coupled to the chassis about a pivot axis at a first location, at least one drive device configured to drive wheels of the machine, a drive belt and pulley arrangement. The subframe is further coupled to the chassis via at least one suspension device at a second location. The at least one drive device is driven by the prime mover and is coupled to the subframe. The pulley arrangement is configured to direct the drive belt from the power take-off of the prime mover to at least one drive pulley on the at least one drive device. The pulley arrangement comprises an idler pulley having a diameter and a rotational axis. The idler pulley is coupled to the chassis such that the rotational axis is spaced from the pivot axis by no greater than 1.5 times the diameter.
