CONSTITUTION:A power from an engine 2 is introduced through an input power shaft 9 into a mission casing 3 which incorporates therein a safety clutch 6, a counter gear transmission unit 7 which is changeable in two high and low speed stages and a main gear transmission unit 8 which may be changeable in three forward shift stages and one backward shift stage, and is then transmitted to the counter gear transmission 7 through the safety clutch 6, the output of which is transmitted to the main gear transmission unit 8 so that the power may be individually transmitted left and right axles 12a, 12b through a pair of steering clutches 11a, 11b, engageablly and disengageably. |
