ABSTRACT:
Within a rear half of a tractor front housing (1) which includes an internal partition wall (1a) and an open rear end, a fluid-operated first speed cleanse mechanism (12) is disposed and is supported, at its rear side, by a bearing support frame (4) which is in turn supported by the front housing. Within a transmission casing (2) which includes an open front end and is fastened to the rear of the front housing, a second speed change mechanism (15) is disposed and is supported, at its front side, by the support frame. A fluid pump (72) for supplying fluid to the first change mechanism is mounted on the partition wall. The support frame includes therein a fluid passage (162) which is adapted to function as a fluid passage for supplying fluid from a fluid sump within the vehicle body to the pump. The passage has first and second open ends (162a, 162b) at front and rear surfaces of the frame for connecting the passage to a pump suction passage (160) and to a fluid sump filter (165), preferably through internal pipes (166, 167).
