Abstract

PURPOSE: To eliminate a main clutch and to reduce size by arranging an auxiliary transmission between a prime mover and a main transmission and coupling the output shaft of the prime mover directly to the input shaft of a transmission.
CONSTITUTION: A clutch type auxiliary transmission II is arranged to the rear half of a conventional clutch housing H, and a transmission case M is arranged on the rear surface of the clutch housing H. Namely, the auxiliary transmission II is arranged between a prime mover I and a main transmission III. A main clutch is eliminated and a power is directly transmitted to a transmission input shaft 11 from the crank shaft of the prime mover I. The main transmission III and an auxiliary transmission IV are arranged at the interior of the transmission case M arranged in a joined state to the rear surface of the clutch housing H. This constitution eliminates a need to arrange a mechanical type main clutch like a conventional tractor and sharply reduces both the longitudinal size and the size in the direction of the width of the transmission case.
