I have been snowblowing for about 25 years and I have broken a few in my day, but not probably for 10 years. I do several things to avoid this problem:
- make sure that there is nothing in the way before the first snowfall.
- I run my SUV up and down the driveway (mostly gravel) after the first snowfall to pack things down.
- run the blower about an inch off the ground the first time for the year.
- clean off the snow after each use so that nothing impedes the augers and impellers the next time I use it. They do get a bit warm and if there is snow in chute or the bottom of the second stage cage it might melt, drop to the bottom, refreeze and then become a block for the impeller blades.
- and lastly I never stress the rig. This is a carryover from my belt driven blower days. If you pushed it too hard, the belt would wear out quickly. I go super slow if the snow load is heavy. I look at it this way. It will take a little longer to go slow, but it will take a lot longer to replace a shear pin.
