Cajun's correct about the farm implements. I'm pretty sure ford did the same thing at some point. I could swear that i've read info or seen pics of things like augers that attach on the rear bumpers for drilling post-holes. I have a koenig winch, but only front drive. I think both PTO's have a similar housing and just cover the unused rear drive outlet with a plate.
oooh--just noticed i have to re-up for contributor!
