Ok now I figure I will have to play with the rear blade idea when is snows,, Now for something completly different,, I came across a bunch of weights from a bar bell set some guy was tossing and being of the generation that every thing has some use,,,someday.... I thought about well maybe some more weight onthe back end, so I was thinking of useing the 3pt hitch and hanging the weights on it on a bar,, soooooo anybody know what size the holes are in a cat 1 3pt hitch?
