ABSTRACT:
A hydrostatic transaxle assembly (11) is disclosed including a central manifold portion (15) and left and right axle assemblies (17 and 19). The axle assemblies include hydraulic motors (37 and 39) connected in parallel through the manifold 15 to the output of a variable displacement pump (13). The transaxle assembly includes a differential mechanism (111), including fluid displacement mechanisms (113) and (115) of which the inner rotors (127) are connected for common rotation by a shaft (117). The differential mechanism (111) includes a selector valve (119; 161) which can either interconnect left and right passages (33b and 35b), downstream of the mechanisms (113 and 115) to permit normal differentiating action, or can prevent such communication between the passages (33b) and (35b) to cause limited differentiating action of the transaxle assembly.
