The engine 1G is arranged so that the output shaft 11 protrudes to the left when viewed from the rear, and the cylinder portion is tilted upward toward the rear. The upper edges of the upright plate portions 6 of the left and right plate members 3 of the machine base 2 are inclined rearward upwardly below the cylinder portion almost along the slope of the cylinder portion, and further rearward from the vicinity of the rear end of the cylinder portion. The rear edge of the upright plate portion 6 extends vertically downward from the rear end thereof. The power of the output shaft 11 is transmitted from the transmission case 8 to an input shaft 12 protruding leftward via a belt/pulley mechanism. That is, the output shaft 11 and the input shaft 12 are each provided with two-stage pulleys 13 and 14 each having two pulleys with different diameters, and the transmission belt 15 is placed between them. The power of ↓ is transmitted to the input shaft 11□2. and the inner pulleys 13a, 14a or outer pulley 13b of the two-stage pulleys 13.14,
By changing the connection of the belt 15 to 14-b, the speed can be changed to two speeds. Further, power transmission is brought into contact with and separated from the belt 15 by a tensioner 16 that can freely come into contact with the belt 15. This tensioner 16 has its base end pivotally supported by a rising portion 6a below the cylinder that tilts upward along the cylinder portion of the standing plate portion 6 of the machine base 2, and is attached to a belt tension run clutch lever provided at the operating portion of the handle 17. -18 via a spring 19 and a wire 20, and is normally separated from the belt 15 and no power is transmitted (in that case, the stopper device 21 provided on one pulley 13 side (The belt 15 is held apart from the pulley 13), and when the belt tension run clutch lever 18 is operated, it rotates upward and comes into contact with the belt 15, tensioning the belt 15 so that power can be transmitted to the input shaft 12. do. 22 is a cover that covers the pulleys 13, 14, belt 15, etc. Since the upright plate portion 6 is flat, a belt/pulley mechanism, tensioner 16, etc. can be easily assembled therein. The power of the input shaft 12 of the mission case 8 is transmitted to the lower part of the mission case 8 by a transmission chain wound between sprockets disposed above and below inside the mission case 8. The power is transmitted to the rotary shaft 23 disposed in the direction, and the tilling rotary 24 is rotationally driven.

And the left and right side pieces 2 on the rear side of the bracket 25
5a has three mounting holes 27 vertically open, and a bolt 26 is installed between either left or right mounting hole 27 to fix the rear side of the bracket 25 to the rear end of the rising portion 6b. In this way, the front end of the bracket 25 is pivotally attached to the rising portion 6b, and the rear part is attached at a different position depending on the position of the attachment hole 27, so that the attachment position of the bracket 25 changes in three stages. The handle base is fixed to the inside of the left and right ends of 25b, and the posture of the handle 17, which extends rearward and upward, changes. In this way, the height of the handle 17 can be adjusted in three levels. The handle attachment portion of the upper piece 25b of the bracket 25 has an upwardly convex curved surface along the circumferential surface of the handle 17.
