Willl, 'those' is actaully ONE big-*** piece made of plates. It is the bracket for the model 261 5-foot RFM (has rear castors only, front of deck 'hinges off the tractor via chains that hook to this bracket) I use to chop the grass. It also becomes the rear mounting point for that middle link. It stays on my tractor full-time, does not hamper any other uses (so far).
Lincoln, what size excavator? Did you say 'rent' or 'hire' ? My brother offered to use a mini-excavator but then saw the trees/stumps and said 'no thanks, too big'. I agreed.
