B2710 with HST, I was using post hole digger and tractor was really laboring, our soil is really rocky. I heard/felt a loud bang so I stopped. Here's the situation:
* 3pt arms won't raise. they dropped to the ground freely and I can raise them by hand, but the hydraulics won't lift them.
* PTO shaft turns, but I can't put a load on it so I don't know if it really works.
* The tractor will move but it makes a bad noise like there are parts clanging around in the transmission.
* I have the proper shear bolts on the auger, neither of them failed but were very bent. The bolts on the PTO shaft did not shear either.
Trying to decide how to proceed, it seems almost certain something broke in the rear PTO section of the transmission. I also think the clutch may have been slipping while this failure occurred. I noticed after the loud bang when I looked the other direction that there was smoke coming from under the tractor. The wind was carrying it in the opposite direction I was looking when things broke, so I'm not sure how long that was going on. The noise when I drive it might be some broken part that ended up in the transmission where it shouldn't be. I'm reluctant to drive it given the noise it makes, it's only a few hundred yards from the shop so maybe I can tow/shove it into the shop.
Any advice on diagnosing this before I tear into it is welcome.
