Tractor: LS MT235HE
Blower: Land Pride SB1574 three point snow blower
Shear pins: Two; a grade five 1/4x1" on the auger shaft, and a Grade two 5/16's x 2" on the PTO shaft
Had an odd situation a couple weeks back. Temp was about zero F give or take a degree or two. I was blowing some snow and snagged something that caused the PTO shear pin to snap. I replaced it and then thought I should also check the auger shear pin. Here is the odd part...
The shear pin had broken and the shear pin holes were 180 degrees out of rotation. I tried to rotate the auger to line them up, but it would not budge. I tried to turn on the PTO to move it and the auger ran fine and it blew snow even though there was no shear pin in place. I figured it was frozen so I sprayed a bunch of window de-icer on it and pinged it with a hammer. It would still not rotate. I was worried it had some how welded to itself. I had about 100 feet of nice dry snow left so I used it to blow that out of the way and parked it. It warmed up to around 30 degrees F a few days later. I went out to check it and it now rotated freely. So clearly it was somehow frozen to itself.
Has anyone seen this happen? It was cold out, but not 40 below! Any suggestions on how to unfreeze it should it recur? I suppose I could have hit it with a torch.
