I looked for a tractor for quite a while and ended up buying a 5310. It’s 4wd with loader. It appeared in great shape. No leaks. Everything was in working order. The tractor operates perfectly. I blew a front tire clearing honeysuckle but that was a 1 in a million chance at snapping a valve stem. Sucked. Had the tire fixed and went back to work. With the cold weather, it became apparent that both gear shifters became frozen. I couldn’t move them. This is apparently a common problem? I sprayed ether in from the top and that thawed it the first time. The second time, I decided to use a heat gun. It appeared to be working...but as I was wiggling the A, B, C shifter something gave way. I can carefully shift gears but something is wrong in the linkage. Do you think the fork broke? A spring? No telling until I take it apart? Also.....how in the hell can I prevent the freezing problem in the future? It’s beyond annoying.
