Abstract
A transmission for a tractor comprising a propelling line for transmitting an engine output to drive wheels, and a power takeoff line for transmitting the engine output to a working implement attached to the tractor. The transmission further comprises a torque converter including a casing connected to an engine output shaft and an input shaft of the propelling line, and a turbine liner and a lockup clutch connected to an input shaft of the power takeoff line. The propelling line includes a first hydraulic clutch for transmitting the engine output in forward rotation and a second hydraulic clutch for transmitting the engine output in backward rotation, engine output transmission through the propelling line being broken when the first and second hydraulic clutches are disengaged. The power takeoff line includes a power takeoff hydraulic clutch, and a power takeoff gear disposed upstream of the hydraulic clutch for driving hydraulic pumps attached to a transmission case.
