摘要： A hydrostatic transmission includes a hydraulic pump, a hydraulic motor, and a center section. The center section is formed therein with first and second fluid passages connecting kidney ports opened at a pump mounting surface to kidney ports opened at a motor mounting surface. The first and second fluid passages include respective straight portions parallel to the pump mounting surface and the motor mounting surface. When the center section is viewed to face the motor mounting surface, the straight portions of the first and second fluid passages substantially entirely overlap each other. When the center section is viewed to face the pump mounting surface, the straight portion of the first fluid passage is disposed between both ends of the second fluid passage, so that the straight portion of the first fluid passage and the ends of the second fluid passage are aligned on a substantially straight line.
