Abstract
A working vehicle propelled by independently driven right and left running units comprising a body frame with an engine mounted thereon; a front wheel unit for supporting the body frame in cooperation with the right and left running units; a left HST for receiving torque input from the engine; a right HST for receiving torque input from the engine; a left reduction mechanism for decelerating and transmitting torque output from the left HST to the left running unit; a right reduction mechanism for decelerating and transmitting torque output from the right HST to the right running unit; a left base block supported by the body frame, this base block forming a housing base for the left HST and a housing base for the left reduction mechanism; a right base block attached to the body frame, this base block forming a housing base for the right HST and a housing base for the right reduction mechanism. The base blocks are formed as port blocks for the HSTs, and define hydraulic ports in the housing bases for the HSTs.
