Auger blades are spinning

un-seize the auger action
replace rusted bearings

Check to see if the shear pins are broken off if so remove any fragments and replace. if not..With the engine off, try moving the auger with the handle engaged (you may need to have someone hold the handle while you wiggle the auger. If the auger spins freely without moving the belt mechanism you have either a shear pin issue or shaft breakage if it will not move or moves with great difficulty work your way back through the machine looking for the obstruction or damage. If the auger moves freely and the belt pulleys etc. move with it you likely need to adjust/ replace the tensioner, control handle or belt.

The shear pin is sheared off. Somewhere along the auger, you'll find a hole drilled all the way through it. The shaft inside also has a hole drilled all the way through it. Compare the two augers - the holes are USUALLY in a straight line with each other (when one is up/down, the other is also up/down).

Get a replacement shear pin (DO NOT use a hardened bolt!) and put it through the holes when the auger holes are lined up with the axle holes.

you bent it straighten it out as to where it works as it should , easy fix , did you get the bad tile out

gear case is shot

if auger wont spin heat it up a little

If you start the machine and the axles spin but the augers do not it is because the shear pins are broke. If you look closely you will see the the augers have shear bolts and nuts or shear pins. If you jam a piece of ice or a stick in the augers while they are spinning the bolts will shear so you do not damage the expensive augers or the worm drive gears. If the axle spins with the augers you may have torn up the front worm gear in the front of the auger intake. If you spin the small auger and the large auger moves but when you start and engage the auger nothing happens you will have to remove the under cover and inspect the drive belt pulleys for jammed or broken parts or more commonly broken drive belts.

many Sears/Craftsman snowblowers have a shear bolt on the auger shaft or one on each side. This bolt is designed to break under a specific amount of force to prevent damage to the gear box or drive assembly if the blades encounter an immovable object or something becomes jammed (even a newspaper buried in the snow can cause this). They likely broke at some point during use in the past and you did not realize this, or they were not properly installed when the blower was new. If you check the auger shaft and find one or 2 holes that look like something should be there, then you found the most likely problem. If you reply with the model I can tell you exactly where to look and the part # or if you realize the bolts are missing you can contact that parts dept at Sears with your model and they can provide replacement bolts. Can be a pain with small things but a lot less expensive than a new gearbox.

I believe that model has to belts. one for the auger drive and one for the traction drive. I would check the traction drive belt. The is also a rubber drive donut that rides on a melat disc to drive the wheels. Make sure the rubber drive donut is not glazed and cracked, and one other simple thing to check. On the end of each axle is a pin or some kind of locking device that lock the wheel from spinning on the axle. Make sure these are engaged. Goodluck on it.

does the impeller spin and not the augers.if so check sheer bolts.if neither impeller or auger spins check auger belt.
