ABSTRACT:
An articulate tow bar for use with a ride-on for pulling an independent mower unit. The tow bar has first and second members pivotally attached at adjacent ends by a lockable coupling that permits the members to be positioned alternately in a transport position or working position. The first member is pivotally attached to the tractor by a horizontal hinge and the second member is pivotally attached to the independent unit by a universal joint, the pivotal connections permit the tractor and independent unit to operate on hilly uneven terrain. Controls are located on the articulate tow bar adjacent the mower for operating the independent unit which allows the tow bar and the mower unit to be readily adaptable to conventional mowers.
