![]() I need for you to keep this in mind when you check the chain tension that it has ot have tension on the top lacing of roller chainġ. Slop will cause unwanted torque loads in the system. No slop in the final fitting of the shear bolt. The "object" has either been blown out or is up there in the pile ahead of the blower.Īnother thought - when you install a new shear bolt - it should be wrenched down pretty tight. The bolt has sheared - the tension has released. There is an idler sprocket that will allow you to adjust chain tension.Īlso - that object that has caused your bolt to shear will seldom be right there in the auger or impeller for you to find. Are you pushing a big "glop" of snow ahead of the blower. Unfortunately - I got real good at a fast replacement of blown shear bolts.Īre you going too fast. I always had a goodly supply of shear bolts carried on the tractor. That's all the time it would take for the wet snow to freeze up and "BING" - another sheer bolt. Stop for a moment to catch my breath and massage my sore neck & shoulders. A rock, an old chunk of wood, even a frozen pocket gopher, chunks of ice. However, in the day - I always figured to blow, at least, two shear bolts on the first clearing of my mile long driveway. The days of a 3-point blower and going in reverse are loooong over. I also have a chain shear bolt that never broke.I now have a big enough tractor to only need a heavy duty rear blade. I checked chain tension and I gave it a bit more, I dont think that was the issue. Since then its always hit and miss sometimes I can get 4-5 hours per bolt sometimes 5-10 minutes. My father finally broke the original bolt when he engaged the snowblower at full rpm. I was throwing tennis ball size rocks 20 feets in front of the snowblower and never broke a single bolt. The first time I used the snowblower I did not have time to box blade the road so there was alot of rocks. I broke 5 bolts on the last storm and none on the previous one. The total randomness of the situation is what puzzle me the most. I keep looking for piece of wood or rock or ice chunks and I can never find out what caused the pin to break. What frustrate me the most is at one point I am chewing thru old frozen stuff that make a **** of a racket in the auger with no issue and 10 minutes later I am working in fluffy stuff and the bolt break. It pushes it forward and as result it reduces snow caster ability to clear snow. SO much of the frustration in dealing with snow pack is the fact that the crossĪugers do not have serrations to cut the snow as it enters the snow pack and The snow caster to clear off the broken chunks of snow. Then dump it and do that from one end to the other of the lane and then use If you have a loader on your mule you can scoop a little snow off the side and If you can it would be best to raise the snow caster a few inches to allow the snowĬaster to take a partial bite in a half cut at an angle to shear off the snow pack Have you checked the roller chain drive system on your snow caster?Ĭan you take a partial cut of snow off your snow pack if you have room to move? The thing you need to know is that snow pack that has gone through aįreeze thaw cycle just like your snow pack can and will cause a hugeĪmount of resistance that will stop the snow caster from working. The shear bolts are a much more efficient fail safe mechanism. The use of a compression spring type contact flange or the direct contactįlange slip clutch is not required or needed with a snow caster like yours as Mon Ami, we have all been there with the frustrations of snow clearing when ![]()
