Abstract:
A frame having weed pulling apparatus attached thereto is adapted to be attached to a tractor hitch for lifting or lowering the frame. Pairs of pneumatic tires are rotatably mounted along substantially parallel axes. Each of the pneumatic tires has an axle with a sprocket affixed thereto. A chain is arranged to be disposed over a first sprocket and under the next adjacent sprocket, and so forth, for each adjacent sprocket such that each adjacent sprocket and thereby each adjacent wheel will rotate in an opposite direction. A chain lubricating structure is also attached to the frame. Weed guiding mechanisms are provided to prevent pulled plants from being deposited on top of the frame. Two wheels are pivotally attached to the frame in association with hydraulic cylinders. These wheels act as gauge wheels for maintaining the weed pulling apparatus at a desired distance above the ground when in operation, and these wheels also act as transport wheels for moving the weed pulling apparatus to and from the places where it is to be used.
