PROBLEM TO BE SOLVED: To stop the drive of a roll-forming part by opening a rear chamber, and re-drive the roll-forming part at a slow speed by closing the rear chamber.SOLUTION: A whole crop harvesting machine 1 comprises a roll-forming part 5 for forming harvest into a roll shape using driving force of an engine 60, and a rear chamber 52 for discharging the formed roll. The whole crop harvesting machine 1 further includes a first pulley 61 rotated by the engine 60, and a belt 63 and a second pulley 62 for transmitting the driving force to the first pulley 61. The roll-forming part 5 is driven by the rotation of the second pulley. A clutch pulley 64 is separated from the belt 63 by opening the rear chamber 52 to stop the second pulley 62. The clutch pulley 64 is pressurized toward the belt 63 at an alleviated speed via a damper 66 by closing the rear chamber 52 to slowly drive the roll-forming part 5. |
