ABSTRACT:
A transaxle apparatus comprises: a housing; a hydrostatic transmission disposed in the housing, the hydrostatic transmission including a hydraulic pump receiving power from a prime mover, a first hydraulic motor driven in response to fluid supplied from the hydraulic pump, and a center section including an inner fluid passage for fluidly connecting the first hydraulic motor to the hydraulic pump; a first axle disposed in the housing and driven by the first hydraulic motor; a hydraulic actuator disposed outside the housing so as to drive a second axle disposed outside the housing; a port opened outside the housing so as to be fluidly connected to the hydraulic actuator; and a block interposed between the center section and the port in the housing, wherein a fluid passage is disposed in the block so as to connect the port to the inner fluid passage in the center section.
