    Patent number: 4732246
    Abstract: A first clutch control is operated in response to an accelerator position signal so as to set a clutch from a disengaged state to a half engaged state. A second clutch control is provided for gradually engaging the clutch when a load signal from an engine load detecting is equal to or higher than a preset value, and for disengaging the clutch when the signal is higher than the preset value. After the second clutch control is operated when a difference between an engine speed and a clutch output shaft speed becomes equal to or lower than a predetermined value, the clutch is fully engaged by a third clutch control.
