Well thanks for all the great ideas, yes the tractor is still under warranty, but I don't consider loose bolts would fall under warranty it's more just maintenance issue. The funny thing is after a season of rock picking with a big old rock bucket not one loose bolt, but a little bit snow and ice and I've got a loose loader go figure, must have something to do with the cold ;-). Tomorrow in the warm shop things might look a little different, not laying on the cold ground, plus I like the idea of the welding the nuts to the back of the frame so I don't have this problem again something tells me it's going to happen again.
