I'm thinking about cannibalizing a mast from a counterbalance unit to make a fork arrangement, to be tractor mounted on the rear of a similarly massive tractor, with at least double the width and significantly more counterbalance fulcrum length.

I don't expect to get a gold star from Crown, but what do you guys think about that? I would definitely not be operating this moving while the mast is raised, and would never use it to lift above 5 feet while near capacity.
