I have a B7100HST 4WD. I purchased a used frontend loader that was supposed to fit this tractor. There apperars to be some parts missing from what I have recieved. the pla\tes that are to go to the tractor chassis is 1" wider than the actual tractor chasis. and the bolt holes on the loader are smaller than the bolts on the tractor. If I had to guess I would say that there is some adapter plates missing. can anyone help me out with this?
