Claims

[Scope of utility model registration request]

The upper end of a transmission case is fixed to a frame that is removably attached to a tractor, and a rotor shaft that drives a rotor that is removably attached to the lower end of the transmission case is horizontally mounted and placed above the frame and the rotor. The cover frame of the rotor cover is connected with the upper and lower links, and the frame, the cover frame, and the upper and lower links form a parallel link mechanism, which is screwed into the threaded hole of the bearing shaft that is rotatably supported horizontally on the above link. A rotor cover up-and-down device for a rotary type power cultivator, in which a lower end of an adjustment bolt with a handle is rotatably fitted to a support shaft rotatably suspended horizontally on the frame.
