ABSTRACT:
A transmission for a working vehicle like a tractor of the invention is housed in a transmission housing 1 interposed between an engine and a rear axle housing 2. An interior of transmission housing 1 is divided into a front chamber A and a rear chamber B through a partition wall 1a. In front chamber A is disposed a main-clutch system partition centering a traveling-input shaft 7. In rear chamber B is disposed a speed-changing system as a combination of reversing arrangement and multi-speed-changing arrangement. In a rear opening of housing 1 is disposed a bearing plate 3. In rear chamber B, a first speed-changing shaft 8, a second speed-changing shaft 9 and a front transmission output shaft 10 are supported in parallel between wall 1a and plate 3. A regular speed-reduction gear train and a reversing speed-reduction gear train are interposed between shafts 8 and 9, so that shafts 8 and 9 can be connected with each other through one of the gear trains by a first clutch device C1 on shaft 8. A second clutch device C2 is on shaft 9 so as to selectively connect shafts 7 and 9 directly. A plurality of gear trains for multi-speed stages are interposed between shafts 9 and 10, so that shafts 9 and 10 are connected with each other through one of the gear trans by a third clutch device C3 on shaft 10. A cover 51 is settled on housing 1. A main (second) speed-changing lever 52 and a sub (first) speed-changing lever 52 are disposed respectively at both lateral sides of cover 51. Third clutch device C3 is operated by lever 52. First and second clutch devices C1 and C2 are selectively operated by lever 55.
