A transaxle apparatus (10;20) comprising an axle (12L,12R;22L,22R) having an axis and a housing (46,47) supporting the axle (12L,12R;22L,22R), wherein the housing (46,47) includes a first housing member (46) and a second housing member (47) which are joined to each other through a joint surface along the axis of the axle (12L,12R;22L,22R). A hydraulic motor (40) is disposed in the housing (46,47), wherein the hydraulic motor (40) includes a cylinder block (43) and a motor shaft (41) engaged to the cylinder block (43) and extended parallel to the axis of the axle (12L,12R;22L,22R). A member (62) is disposed in the housing (46,47) and incorporates a pair of kidney ports (62a,62b) fluidly connected to the cylinder block (43). A pair of caps (54a,54b) are fluidly connected to the cylinder block (43), and a gear train (135) is disposed in the housing (46,47) so as to drivingly connect the motor shaft (41) to the axle (12L,12R;22L,22R). The pair of caps (54a,54b) are disposed in the housing (46,47) so as to be fluidly connected to the respective kidney ports (62a,62b) and are extended and opened outward from the housing (46,47) so as to receive and deliver fluid from and to a hydraulic pump (30) disposed separate from the housing (46,47).
