ABSTRACT:
A flip-up shield assembly for a tractor PTO in which the shield can be moved from a normal position in which it extends above and to the sides of the PTO shaft to and held in two raised positions, one of which is intended for use when a drive shaft having an oversized universal joint guard is attached to the PTO shaft and the other of which is intended for use simply during the coupling of a drive shaft to the PTO shaft. The shield can be moved to and held in an additional protection position which is located below the normal protection position to provide additional space for an adjustable implement hitch which is adjustably carried by a vehicle above the PTO shaft.
