1. Remove the belt cover with a socket wrench. Slide the belt cover off and set it aside.
2. Remove the two belt cover stud bolts with a socket wrench to get to the auger belt guide.
3. Remove the belt guide with a socket wrench.
4. Push down on the belt tensioner pulley with your hand. Remove the old belt and set it aside.
5. Install the new belt and release the belt tensioner pulley to tighten the belt.
6. Re-install the belt guide with a socket wrench and tighten the bolt.
7. Re-install the two belt cover stud bolts and tighten with a socket wrench.

I pulled the following from a snaper model similar to yours.
The snowthrower has two drive belts, one for the traction
drive-which transmits engine power to the wheels, and
a second for the auger drive-which transmits engine
power to the auger mechanism.
Each of these drive belts are of special construction and
should be replaced only with genuine replacement belts
which match the original equipment belts. These are
available from your dealer.
Traction Drive Belt Replacement I pulled the following from a snapper model similar to yours. Believe it should help.
1. Disconnect spark plug wire and fasten it away from
the spark plug.
2. Remove belt cover. (Located in back of the discharge shute).
3. Pull the traction drive belt idler pulley arm (See
Figure 24) away from the belt to relieve tension, and
slide the belt off the engine pulley.
4. Slip the belt off from around the traction pulley (See
Figure 29) and pull the belt out of the unit between
the auger pulley and the traction pulley (the lower
cover need not be removed for this step).
5. Reverse the procedure to install the new belt. Be
sure there are no twists in the belt, and that the belt is
properly seated in the pulley grooves.
6. Replace the belt cover.
7. Start the unit, and check the traction drive for proper
operation. See "Traction Clutch Cable Adjustment"
for adjustment procedures.
There are also several videos on YouTube on changing snowthrowr belts. (Didn't see one for your blower, but most similar and should provide a good starting reference).
Hi, The only thing I can think of is that your sheer pins are broken. Can you turn the auger by hand? If you can, look at the shaft that the auger is welded to, If you can look for bolts or holes on the auger center shaft, You will have to punch out anything that is left there. If that's the problem measure the diameter and length of the old bolts, or go to a shop that sells parts to get new sheer pins. You can also use ordinary bolts that will work well. Have you checked your belt to see if it is broken or has come off the pulley or if the belt tensionner is still on the belt or has come off not providing the right amount of tension so the belt does not slip in the pulleys and is able to turn the auger. Regards and good luck. I hope that is the problem and can be fixed easily and is cheap to do.
The most common cause of this is the drive belt is worn.
If you remove the cover (usually plastic) in the middle of the snow thrower and look at the belts.
Your operator's manual will show you how to remove the cover and check/change the belts.
The belt closest to the blower assembly drives the auger/blower and the belt closest to the engine drives the transmission.
With the engine not running, have someone depress the drive lever and check the blower belt.
You should only be able to depress the long side 1/2 inch or less. More than that the belt has stretched and needs to be replaced.
On some older blowers you can adjust the tension pulley, but most made in the last 15 years, you can't.
The belt may be frayed on the edges or glazed causing it to slip (it is shiny on the sides of the belt) It may be torn and broke completely.
You can get parts for you Craftsman and most Husqvarana, MTD made models through searspartsdirect.com. You can also get parts through jackssmallengines.com or your local dealer.
If you are unfamiliar with repairing machines take it to your local dealer. They will have a technician troubleshoot and repair the unit.
Feel free to ask any other questions to troubleshoot this problem farther. I know Snow Blowers. Please remember to rate this answer!

Remove the auger belt housing cover 4 bolts (10mm), if you are lucky, you can take the belt out, or just cut it. The slide the new belt between the auger and driving pulleys. there is a break pad under the auger pulley, so have someone engage the auger handle and put the new belt on the auger pulley. Or you can remove 10 12mm bolts and separate the auger and engine. Even though you have remove more bolts, it is easier.

There is a service bulltin on this I have not seen this yet, Ill paste it for you to look at .
this was issued dec 22-2003 you would think that it would have shown up as a problem by now.

SUBJECT: Traction belt jumps off the pulley. SITUATION: Incorrect pulley alignment causes the traction belt to jump off, usually when the drive is disengaged or as a hill is crested. CORRECTION: 1. Remove the belt cover, engine belt guide and the bolt securing the crankshaft pulley. 2. Remove the auger brake assembly. 3. Remove the crankshaft pulley and the auger belt. 4. On the left side of the machine, remove the hair pin cotter from the speed control link and slide the link out of the pulley pivot assembly. The traction belt can now be removed. 5. Shorten the pulley half nearest the engine (PN 106-7334) shown in Fig 1. Grind or machine 1/8” (.125”/3.2mm). from the hub end of the pulley. The new finished length of the pulley half should be 1.07” (2.7cm). 6. Chamfer the bore to ensure the pulley fully contacts the shoulder on the crankshaft. You can send the pulley to an outside machine shop if you do not feel that you can modify the pulley in house. 7. Reinstall the pulley with a new traction belt. A. Chamfer edge after grinding/machining. B. Remove 1/8”. C. Masking tape used as a reference line. 8. With the engine off, engage both the traction and auger levers and inspect the alignment of both the auger and traction belt idler pulleys (Fig. 2). Since we have moved the crankshaft pulley it may be necessary to bend the idler arms slightly to center the belts. Adjust as needed. 9. Install the engine belt guide and test operate. 10. Install the belt covers.
No. If you have someone squeeze the auger handle, that will allow you to remove the belt. You'll need to do the same to put it back on. Make sure to put the belt on the bottom pulley and not over one of the belt guides otherwise you will end up replacing the new belt also.
