PURPOSE:To enable an inexpensive belt variable transmission device to be favorably utilized for the traveling transmission of a combine by solving sane programs on a fear of runaway of a machine body on a slope and a slippage at timing of clutching at the time of starting at traveling neutral for disengaging a main clutch. CONSTITUTION:Power of an engine 1 is inputted into a transmission 5 via a belt variable transmission device 4 having a driving pulley 18 formed into a split pulley structure in place of a high speed transmission, and a belt driving mechanism with a main clutch 3 is installed over the engine 1 and this belt variable transmission device 4. Also there is provided a dead-point type continuous clutch operating mechanism B for driving an electric motor 13 quickly selecting the main clutch 3 to declutching from the clutching, while a brake A and the motor 13 are interlockingly connected to each other so as to make the brake A, installed in the transmission 5 in linkage with disengagement of the main clutch 3, be operated. |
