To provide a work vehicle transmission which: comprises a predetermined transmission mechanism having a plurality of forward shift stages to move a work vehicle forward and a backward shift stage to move the work vehicle backward; and can improve operability when switching between the forward shift stages and the backward shift stage.SOLUTION: A transmission 30 of a work vehicle 1 comprises an auxiliary transmission 50 which has a plurality of forward shift stages to move the work vehicle 1 forward and a backward shift stage to move the same backward. The plurality of forward shift stages include a low-speed shift stage with the largest transmission gear ratio among the plurality of forward shift stages and a medium-speed shift stage with a transmission gear ratio most close to that of the backward shift stage among the plurality of forward shift stages.SELECTED DRAWING: Figure 3

    【課題】作業車両が前進する複数の前進変速段と作業車両が後進する後進変速段とを有する所定の変速機構を備える作業車両の変速装置であって、前進変速段と後進変速段との切り替える際の操作性を向上できる作業車両の変速装置を提供することを目的とする。【解決手段】作業車両1の変速装置30は、作業車両1が前進する複数の前進変速段と前記作業車両が後進する後進変速段とを有する副変速機構50を備える。複数の前進変速段は、複数の前進変速段のうちで変速比が最も大きい低速変速段と、複数の前進変速段のうちで変速比が後進変速段の変速比に最も近い中速変速段と、を有する。【選択図】図3
