1. A hitch attachment for connecting an implement to an ATV wherein the ATV comprises a frame mounted on ground wheels, a drive system for driving the ATV, a rear hitch attached to the frame and a rear rack attached to the frame, the hitch attachment comprising:

  • an attachment frame;

    a hitch coupling mounted on the attachment frame;

    the hitch coupling being arranged such that when connected to the rear hitch the hitch coupling is rigid relative to the rear hitch;

    the attachment frame being mounted rigid relative to the hitch coupling such that the attachment frame is carried rearwardly of the rear hitch at a position which is held rigid relative to the rear hitch;

    two brace arms each connected to the attachment frame on a respective side thereof and each arranged to extend upwardly from the attachment frame to a respective connection location on the rear rack and each including a coupling member for connection at the connection location;

    a rigid connecting member having couplings thereon for rigid connection to a forward end of an implement such that, when the implement is connected to the rigid connecting member, the rigid connecting member remains at a fixed orientation to the implement;

    a pivot mounting for mounting the rigid connecting member on the attachment frame for pivotal movement about a horizontal pivot axis transverse to the rear hitch;

    and an actuator for effecting pivotal movement of the rigid connecting member about the pivot axis between an operating position in which the rigid connecting member holds the implement in fixed operating position extending rearwardly from the rear hitch and a transport position in which the rigid connecting member is rotated around the pivot axis to rotate the implement around the pivot axis to a raised transport position;

    wherein the attachment frame includes first adjustment mountings for mounting the pivot mounting of the rigid implement mounting frame by which the height of the pivot axis on the attachment frame can be adjusted and second adjustment mountings for mounting the actuator by which the height of the actuator and the height of the pivot axis on the attachment frame can be adjusted, with the first and second mountings arranged for common height adjustment of the pivot axis and actuator such that, at each position of adjustment, the angle of the rigid implement mounting frame about the pivot axis in the operating position remains the same.
