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.
