ABSTRACT:
A direction-reversing mechanism (20) is disposed between a primary shaft (17) and output shaft (19) which are arranged in parallel with each other with the output shaft being arranged at a level lower than that of the primary shaft. A first fluid-operated speed change mechanism (23) is disposed between a first drive shaft (21), arranged co-axially with and coupled to the output shaft, and a first driven shaft (22) arranged in parallel with the drive shaft. The drive shaft is arranged at a level lower than that of the driven shaft, and plural fluid-actuated clutches (63, 64, 65) are mounted on the drive shaft. A second fluid-operated speed change mechanism (24) is disposed between a second drive shaft (26), arranged co-axially with and coupled to the first driven shaft, and a second driven shaft (27) arranged in parallel with the second drive shaft. The second driven shaft is arranged at a level lower than that of the second drive shaft, and plural fluid-actuated clutches (75, 76, 77) are mounted on the second driven shaft. The fluid-actuated clutches mounted on the transmission shafts (21, 27) of low levels do not highten the level of an upper surface of the vehicle body and allows to arrange valve means for the first and second change mechanisms concentratedly on an outer surface of the vehicle body.
