Claims

[Scope of utility model registration request]

A main rotary cover that covers the rotation trajectory of the tilling claws rotating around a rotary tilling shaft from above is fixed, an auxiliary cover that moves back and forth along the rear upper surface of the cover, and a rotation of the rear end of the auxiliary cover. A rotary tiller comprising a rear cover connected to a fulcrum and hanging down so as to be swingable back and forth about the fulcrum, the position of which can be integrally adjusted and fixed by an adjustment mechanism connected to the auxiliary cover.
