Abstract

Apparatus for maintaining a tool bar in a controlled position behind a tractor having a conventional three-point hitch arrangement including an upper arm and a pair of lower lift arms. The apparatus has a tool bar positioned near the tractor extending in a direction generally perpendicular to a line of travel of the tractor and at least two upper mounts laterally spaced apart and fixedly connected to the tool bar for pivotal connection to the upper arm of the conventional three-point hitch. Each of the upper mounts has at least one apertured plate, and multiple spaced apart lower mounts laterally spaced apart and fixedly connected to the tool bar are associated with each upper mount for pivotal connection to the lower lift arms of the conventional three-point hitch. Connection of the tractor to one of the upper mounts and the multiple lower mounts associated therewith provide the tool bar with a first centerline and connection of the tractor to another of the upper mounts and the multiple lower mounts associated therewith provide the tool bar with a second centerline spaced from the first centerline one-half the lateral distance between crop rows.
