I guess if anything was screwed up it would be obvious, the metal parts seem to be tight to each other and the levers locked. When the guy delivered it we had a bit of an issue changing FEL and blade but it was obvious, the levers did not match up and would not lock. I thought the pins went in farther but after looking at it this morning there is no way they could. Just the pangs of getting familiar with implements, better than waiting until it is 50 below and 50 mph winds. Modified my chains to fit tight on front wheels and they turned out great, actually had to remove a few links. Advantage that I already see using front chains is that you can lift the front up with the FEL to put them on without having to move the tractor.
