The hitch can be set to work directly behind the tractor or offset to the right or left, which is ideal for orchards or vineyards.

 

Moving the tongue on the hitch bar (1) provides a course adjustment.

 

Changing the angle of the hitch tongue, through a series of holes (2), fine-tunes adjustments.

 

The clevis (3) can be assembled so a disk harrow can be used with tractors having either a straight or open-type drawbar.
