PROBLEM TO BE SOLVED: To provide a rotary tiller stopping slip-off and preventing generation of loosening and rattling of an attachment frame in a support frame by inserting a lock pin into an adjustment pinhole of the attachment frame and press-fixing the attachment frame. SOLUTION: The rotary tiller is constituted by bringing the support frame 26 provided above a tilling unit 15 into a hollow pipe, internally engaging the attachment frame 27 of a tool bar 29 to be freely slidable and inserting the lock pin supported at the support frame 26 to be reciprocally movable into either a plurality of adjustment holes bored in the attachment frame 27 to regulate the reciprocal movement of the tool bar 29 and pressing the attachment frame 27 to one side of the peripheral surface of the support frame 26 to inhibit loosening and rattling of the tool bar 29.
