Abstract

Ride-on equipment includes a pair of front wheels, a pair of rear wheels, a main frame, a subframe pivotally coupled to the main frame about a pivot axis, a power source, and a transaxle assembly. The power source is coupled to and supported by the main frame and includes a drive pulley. The transaxle assembly is configured to pivot with respect to the power source, is operably coupled to the pair of rear drive wheels, and includes at least one driven pulley. The drive pulley and the at least one driven pulley are operably coupled by a belt such that the at least one driven pulley of the transaxle assembly is configured to be driven by the drive pulley of the source via the belt.
