Abstract

A three point hitch for attachment of an implement to the rear of a construction vehicle. The three point hitch uses brackets fixed to the vehicle with a frame mounted thereto. An intermediate part is movably attached to the frame. A hydraulic cylinder operates between the frame and the intermediate part to lift and lower an implement attached to the intermediate part. Attachment of the implement to the rear of the vehicle allows the operator to drive forward and to drag the implement behind. The frame call be detached from the attachment points on one side of the vehicle and can bc swiveled aside to allow access to the construction vehicle.

Claims

1. A movable hitch device for attaching an implement to the rear of a construction vehicle, the hitch comprising:

means for holding affixed to the rear of a vehicle, the means for holding forming attachment points;

a frame connected to the attachment points of the means for holding;

an movable intermediate part connected to the frame; and

means for raising and lowering the movable intermediate part, wherein an implement being attached to the intermediate part can be positioned for use and repositioned from the position for use.

2. The movable hitch device for attaching an implement to the rear of a construction vehicle according to claim 1 further comprising a lower frame attachment part attached between the frame and means for holding.

3. The movable hitch device for attaching an implement to the rear of a construction vehicle according to claim 1 wherein the implement comprises a rake.

4. The movable hitch device for attaching an implement to the rear of a construction vehicle according to claim 1 wherein the hitch comprises a three point hitch

5. The movable hitch device for attaching an implement to the rear of a construction vehicle according to claim 1 wherein the construction vehicle comprises a front end loader.

6. The movable hitch device for attaching an implement to the rear of a construction vehicle according to claim 1 wherein the means for raising and lowering the movable intermediate part comprises a hydraulic cylinder.

7. The movable hitch device for attaching an implement to the rear of a construction vehicle according to claim 1 wherein the attachment points comprise brackets mounted to the vehicle.

8. A removable hitch device for attaching an implement to the rear of a construction vehicle, the hitch device comprising:

means for holding affixed to the rear of a vehicle, the means for holding forming attachment points; and

a frame connected to the attachment points of the means for holding, the frame forming at least one vertical axis between the attachment points, wherein the frame being swivelable about at least one vertical axis.
