<p>A transmission of a tractor is provided to simplify the structure and save the cost in mounting a forward/backward motion converter between an engine and a transmission. A transmission of a tractor comprises an engine and a forward/backward motion converter(12). The forward/backward motion converter converts rotational direction of between transmissions for transmitting power from the engine to a driving wheel. The forward/backward motion converter comprises an advancing high-speed clutch(27), an advancing low-speed clutch(31), and a backing clutch(29). The advancing high-speed clutch converts power transmitted from the engine to a high-speed advancing side, the advancing low-speed clutch to a low-speed advancing side, and the backing clutch to a backing side. The transmission further comprises a hydraulic clutch operated by supplying hydraulic fluid to the clutches.</p> |
