  • Patent number: 4184558
    Abstract: An agricultural implement has a forwardly extending tongue connectible to the drawbar of a towing tractor and includes a fore and aft drive shaft that is disposed above the tongue and adapted to be connected to the PTO output shaft of the tractor by a PTO hookup assembly that includes front and rear universal joints respectively connectible to the implement drive shaft. When the hookup assembly is not connected to the tractor, the front end of the assembly is supported on the implement by a support that includes a support member swingably mounted on the implement tongue for shifting between a folded storage position and an upright operative position.
