る。このようにして細土耕耘が進行される。 Next, the effect will be explained. When the agricultural tractor enters the field and plows the field, the change lever 12 is operated and switched so that the tilling shaft 11 rotates in the forward direction, and when the machine body 1 is advanced to till the soil, the forward and reverse claws 17, 17, . . . Cut into the soil in front of the tilling shaft 11 from the blade edges 20, 20..., chopping the soil vertically and horizontally, and release a large chunk of tilled soil backward from the bottom of the tilling shaft 11, and tilling middle claw holders 13, 13...
The straw that tries to get entangled with the straw is the straw removal plate 16, 16...front edge 1
4, 14... and forward/reverse rotation claws 17, 17..., and are guided by the front arc edges 18, 18... and are thrown backward together with the tilled soil. If fine soil tilling is required to perform ridge work at the same time,
When the change lever 12 is operated to the reverse side and the machine 1 is advanced while reversing the tilling shaft 11, the forward/reverse claws 17, 17... will move to the opposite blade edges 21, 21...
A cut is made into the lower layer of the soil below the tillage shaft 11, the soil is chopped vertically and horizontally, and the fine tilled soil is carried around from the bottom to the top, and the thin tilled soil is thrown backward along the tillage cover 29. Ru. Then, the straw that tried to get entangled in the claw holders 13, 13... is removed from the straw removal plates 16, 16... and the rear edges 15, 15... and the forward/reverse claws 1.
7, 17... Guided by the rear arc edges 19, 19, it moves to the tip side and is thrown backward together with the tilled soil. In this way, tilling of the fine soil is progressed.
