フト23に伝動され、耕耘ロータ24が回転駆動される。The engine 10 is mounted on the front part of the horizontal part of the left and right plate members 3 of the machine base 2. In the engine 10, the output shaft 11 projects leftward when viewed from the rear, and the cylinder portion is arranged so as to incline rearward. The upper edges of the standing plate portions 6 of the left and right plate members 3 of the machine base 2 incline rearward below the cylinder portion substantially along the inclination of the cylinder portion and further rearward from the vicinity of the rear end of the cylinder portion. It extends upward, and the rear edge of the standing plate portion 6 extends vertically downward from the rear end thereof. The power of the output shaft 11 is belted to the input shaft 12 protruding leftward from the transmission case 8.
It is transmitted via a pulley mechanism. That is, the output shaft 11 and the input shaft 12 are provided with two-stage pulleys 13 and 14 each having two pulleys having different diameters, and a transmission belt 15 is hung between them to transfer the power of the output shaft 11 to the input shaft 12. Be transmitted to. Then, by shifting the belt 15 around the inner pulleys 13a, 14a or the outer pulleys 13b, 14b of the two-stage pulleys 13, 14, the gear can be shifted in two stages. Further, the transmission of power is brought into and out of contact with the tensioner 16 that can come into contact with the belt 15.
The tensioner 16 has its base end tilted upward along the cylinder portion of the upright plate portion 6 of the machine base 2 and a rising portion below the cylinder.
It is pivotally supported by 6a and is connected to a belt tension clutch lever 18 provided on the operating portion of the handle 17 via a spring 19 and a wire 20, and is normally separated from the belt 15 so that power transmission is not performed ( In that case, the belt 15 is held apart from the pulley 13 by the stopper device 21 provided on the one pulley 13 side), and when the belt tension clutch lever 18 is operated, the belt 15 rotates upward to contact the belt 15. Contact and stretch the belt 15 to input power 12
Can be transmitted to. 22 is the above pulleys 13 and 14 and the belt 1
It is a cover that covers 5 etc. Since the standing plate 6 has a flat surface, the belt / pulley mechanism and the tensioner are
16 etc. can be easily assembled. The power of the input shaft 12 of the mission case 8 is
A transmission chain wound between sprockets arranged above and below the inside of the transmission case 8 transmits the transmission to a rotor shaft 23 that extends through the transmission case 8 in the lower part of the transmission case 8 and is arranged in the left-right direction. To be done.
