  • Cultivator drag bar and mounting therefor
    Patent number: 4699219
    Abstract: The support wheels and drag stake of a motor driven cultivating device are connected to the main frame of the device by independent mounting brackets at a location rearward of the tines. The support wheels and drag bar are interconnected by a sliding collar-bar which is rigidly attached to the axle of the wheels, thereby allowing for the simultaneous pivoting of drag stake and support wheels between a forward transport position, wherein the drag stake is in an inactive elevated position, and a rearward working position, wherein the drag stake is disposed at an angle off of the vertical for engaging the earth and retarding the forward progress of the device.
