IMO, yes. /forums/images/graemlins/frown.gif Juryrigging a loader to fit a tractor it's not meant for, no matter how good ones skills, can result in a tractor and loader combination that's dangerous to operate. While it might be possible to get the loader attached and all the hoses properly hooked up so the loader goes up and down and the bucket tilts, are you going to trust using it?

No offfense intended, but marrying a loader to a tractor it was not meant for is not the way to learn.
If the loader your uncle has is not meant for the tractor you find, I agree with MMM, sell the loader and put the funds towards buying a tractor with a loader.
