PURPOSE:To lower change in the number of rotation of an input axis by providing a main clutch adjacently to a fly wheel and combining a clutch case, fitted to the fly wheel, with an input axis or PTO clutch. CONSTITUTION:A main clutch 2 puts a friction plate 9 in engagement with an input wheel 8 so that rotation of a fly wheel 6 is transmitted to an input axis 7 for traveling, while a clutch case 11 fitted to the fly wheel 6 is in contact with the friction plate 9 through a friction plate 13. When a clutch piston 16 is pushed leftward, the friction plates 9, 13 are united in one body and the power of the fly wheel 6 is transmitted from the input axis 7 for traveling to a traveling system speed change gear via an input wheel 8. PTO clutch 3 combines an input axis 25 with the rear part of the clutch case 11 by means of a spline and, when a clutch piston 35 is pushed leftward, friction plates 27, 33 are combined into one body and the power transmitted to the input axis 25 is taken out by means of a taking out axis 30. |
