Abstract
A power transmission structure for a working car provided at the center thereof with a working machine, such as a mower. Power is transmitted by the simplest mechanism from a vertical engine to axles and the working machine. Two output pulleys are attached to a vertical rotary output shaft of the vertical engine. One pulley drives a pump shaft of an axle driving unit and the other pulley drives an input pulley of the working machine. A hydraulic power transmission and a differential gear are laterally eccentrically disposed within the axle driving unit. The hydraulic transmission comprises a hydraulic pump and a hydraulic motor. Power is transmitted from the rotary output shaft of the vertical engine to a vertical pump shaft of the hydraulic pump. A motor shaft of the hydraulic motor is operatively connected to the differential gear.
