Abstract

A shift power transmission apparatus of a tractor that has a small up-down width or a small transverse width and a short front-rear length. A shift output unit is located further toward a vehicle rear side than a combined planetary power transmission unit. A planetary unit output axis and a shift unit input axis are coaxial with each other. A power transmission unit, that transmits motive power from an engine to a continuously variable transmission unit and the combined planetary power transmission unit, includes a rotary power transmission shaft, a pump transmission unit and a planetary transmission unit, the rotary power transmission shaft being interlockingly joined to an output shaft of the engine and extending in a direction along a vehicle front-rear direction, the pump transmission unit being configured to input motive power of the rotary power transmission shaft to the continuously variable transmission unit, and the planetary transmission unit being configured to input motive power of the rotary power transmission shaft to the combined planetary power transmission unit.
