Title: Transmission for self-propelled working vehicles

Abstract

A self-propelled working vehicle is described wherein left and right rear wheels are driven by engine through a transmission path including therein before a differential gearing for the rear wheels a hydrostatic transmission and speed-change gearing which are connected in series with each other. There are provided a mid-PTO shaft for driving a working implement of mid-mount type and a rear-PTO shaft for driving a working implement drawn by the vehicle, a transmission for transmitting power from the engine to the rear wheels and to the PTO shafts. There is provided between the left and right rear wheels a transmission case which supports rotatably at left and right sides thereof the wheels and which journals the PTO shafts in a fashion such that the mid-PTO shaft extends forwardly from the case at a low level thereof whereas the rear-PTO shaft extends backwardly from the case at a middle level thereof. The hydrostatic transmission is fixedly arranged on the front of the transmission case at a level about the mid-PTO shaft in a fashion such that hydraulic pump thereof driven by the engine is disposed above hydraulic motor driven by the pump, shafts of the pump and motor being projected intomore » the transmission case.« less
