Snowblower doesnt throw snow - How to tighten auger pulley belt?

I have this 5-year-old Sear snowblower and, last winter, occasionally, it did not throw snow far or it didnt throw snow at all.

When I opened it up yesterday, I found that the auger belt appeared slack or loosen. But the problem is that the auger pulley appears fixed and not to have an adjustment bracket with a screw that can be slided forward to tighten the auger belt. See attached photos. Thanks.

That belt is supposed to be loose. Using someone's help.....watch the auger belt and pulley while the auger handle is squeezed and you should see the belt tighten up. That's the clutch mechanism for the auger. You should have a threaded adjustment at the base of the auger engage rod (below handle). It will have 2 nuts for locking purposes. Watch the action when the auger handle is squeezed and you should be able to determine which way to turn adjustment to make the auger engage properly.

OK. So, it appears you are saying that I should tighten the cable underneath the on/off handle, that connects to the auger pulley.

After starting the snowblower, I did use a rope to wrap around the handle, and see how the auger turned. I found that the auger did turn, but sometimes slow and then picked up speed and then slowed down. Somethig is loosen somewhere.

Before yesterday, I saw a few youtube videos on adjusting auger pulley belt, which require to push forward the auger pulley in its adjustment bracket. But, my snowblower does not have this obvious adjustment bracket next to the auger pulley.

As of now, my snowblower sometimes doesnt throw snow and if it does, the snow doesnt go far.

Be careful



There are several different ways of adjusting the tension. You should be able to watch the mechanism and see it. If your is a cable coming from handle look where it attaches....it might be there. Mine uses a solid rod with a threaded end at the base of the handle.

Pics are also visible now.

Yes, I have also added the video of this snowblower to show the running of the pulley and auger, and the auger doesnt run fast, and actually it slowed down at time, at least while i wasnt taking this video.
