Transmission for working vehicle

摘要

A transmission for a working vehicle equipped with an engine having a horizontal engine output shaft, pair of transaxles for driving right and left drive wheels at variable speeds, and working device comprises a horizontal input shaft, output shaft, first gear train, horizontal PTO shaft, second gear train, PTO clutch and casing. An axial end of the input shaft connects to a flywheel of the engine. The output shaft drivingly connects to the transaxles. The first gear train transmits power from the input shaft to the output shaft. The PTO shaft extends parallel to the input shaft, and is provided with a universal joint connected to the working device. The second gear train transmits power from the input shaft to the PTO shaft via the PTO clutch. The casing supports the input and output shafts and incorporates the first and second gear trains and the PTO clutch.
