发明名称 Rotary tiller device
摘要 A rotary tiller device with a rotor disposed for rotation about a vertical axis is adapted for mounting on the lift arms of a mobile vehicle and includes a yieldable arm suspension mechanism and spring tiller teeth depending downwardly from the rotor, both of which in combination with each other provide uniform tillage depth control of the device. The rotor assembly can be moved laterally inwardly and outwardly with respect to the frame, and the beam can be adjustably swiveled about a vertical axis such that the rotor can be positioned to the left side, right side, or front of the frame or vehicle.
