Abstract
A towed, PTO-driven implement is equipped with a jack that can be selectively coupled to the draft tongue either in a working position at a forward region of the tongue, or in a stored position at a rearward region of the tongue. A PTO drive shaft assembly extends over the draft tongue and a pin for releasably connecting the jack to the tongue incorporates a PTO drive shaft assembly support which is positioned so as to support the PTO drive shaft assembly when the jack is in either of its working or stored positions.
