回転する。In FIG. 1, when the chain wheel 4a and gear 4b fixed to the input shaft 4 rotate, the chain wheel 5a of the intermediate shaft 5 rotates freely, but the intermediate shaft 5 rotates due to the gear 5b meshing with the gear 4b, and the left and right Output shaft 6, free joint 12, input shaft 11, box 1
A vertical shaft 8 with a tilling blade attached to its lower part rotates through a bevel gear 9 inside the shaft.

に取付けた耕耘刃も前記と反対方向に回転する。Next, when the gear 5b is slid and disengaged from the gear 4b and its clutch pawl 5C is engaged with the clutch pawl of the chain wheel 5a, the intermediate shaft 5 rotates in the opposite direction to that in the above case, thereby causing the vertical shaft 8
The tilling blade attached to the tiller also rotates in the opposite direction.

The power transmission mechanism leading to the input box 3 is sealed inside the cylinder 1 that includes the input box 3, and the power transmission mechanism between the input shaft 11 and the vertical shaft 8 is also sealed inside the box 10, so there is no risk of dirt entering the upper cylinder. 1 simplifies the fuselage by connecting the left and right side plates 2, 2 to form part of the mechanism, and the box 10 can not only move left and right, but also tilt forward and backward along the arcuate hole 14. Even if the tilling state is changed by the tilling blade attached to the vertical shaft and the vertical shaft is moved or tilted in this way, the output shaft 6 and the human power shaft 11 are connected by the free joint 12, so power is transmitted smoothly. This produces various effects.
