Thanks for the further replies. Sounds like the bolting I have is more than adequate, from Scotty_vt's reply.
I think I was overly paranoid because of the hills on the property, but it is amazing what a few days of seat time will do for your confidence. I feel pretty comfortable on all of my hills now. I took it on one of the worst hills on the property, got off, pushed on the tractor to rock it and it didn't budge very much. This was after the dealer came out and put on ag tires, loaded, dished wide. It climbs like a mountain goat now!
