The model is a 922003. It runs fine, but the auger wont turn. it looks like the belt is loose, but I keep reading about these shear pins.. any help in where to start would be great. I have no repair manual, and am a beginner in fixing these kinds of things.
Just finished repairing my ariens, 6 years old with aluminum gear box. Same problem encountered. The problem turns out to be the BRONZE gear driven by the worm shaft. Shear bolts did not shear and bronze gear broke about 5-6 teeth. This is why you can move the auger a half turn or so, there are no gears in one area of the gear and as the gear turns to engage the worm drive it will stop. The fix: the cast iron replacement from ariens! About $200 including shipping, got mine from Jack's Small Engine (MD). Fairly easy repair if you are mechanically inclined. Buy yourself a set of roll pin extractors ($20 from Sears), new roll pins, new woodruff key for shaft. You will also probably have to press 2nd stage impeller from shaft with hydraulic press & heat (took mine to my local auto garage). What stinks is ariens seemed to have admitted the design problem with the aluminum gearbox, yet won't help with repair cost! Anyways, I learned a lot about my snowblower for future repair (belt replacement)!

Re: ariens snowblower auger wont turn
With the engine off check to see if the belt tightens up enough when you engage the auger, if it does will have to check to see if there is a filler plug on the gear box if there is than pull the plug (if there is 2 plugs then pull the top one) fluid should drizzle out if nothin comes out than you need to add fluid. you can get a breakdown of your machine at Ariens.com. As far as the shearpins go, there soud be 2 on the auger shaft itself (1 on each side where the auger paddles are). I think it's going to be either the belt needs adjusting or something to do with th gear box.

If you are asking about the pull cord and when you pull it the engine does not turn and the cord pulls super easy it generally means that the dogs inside the cove assembly are not engaging. This may be caused by a broken spring or dog inside the pull cord assembly. You would need to carefully remove the assembly cover from the engine and pull the cord to see if the dogs are protruding from the assembly if not you would need to repair or replace the parts as needed if so then you would have to check if the will still extend under strain, if not then repair if they still protrude under strain you would have to examine the engine where the unit was removed and look for damage or wear and replace parts accordingly. If you are in fact asking about the front or snow auger on the snow blower itself then the most likely answer would be that you have sheared a pin which holds the auger to the shaft that rotates it. The shear pins (as they are called) are designed with softer metal to break if you hit a large piece of ice, stick or rock that may damage more important and expensive parts of the blower if they stayed intact during the incident. To fix this merely find the hole in the auger along the shaft that is no longer pinned (the auger should spin freely) spin it to line up with the hole n the shaft (which may still have a broken piece of the shear pin in it) drive out any remaining pin with a punch and replace with the appropriate pin for your machine. If the pins are intact you may have a bad belt, pulley, or tensioner and you would have to move further into the repair process.
Belt slipping ( too loose or worn out )
Snow too wet and plugs up.
Motor not powerful enough could be running too slow
Could be the gas screw on the carb set too rich and floods or too lean.
Could be trying to blow too much snow at a time.
Depending on the machines age could be just wore out
In saying this I don't know what type or age of your machine
You probably have a small rock or stick jammed in the smaller throwing auger. Carefully rotate the small auger backwards using a stick/board and tapping with a light hammer till the jamming object pops out. Be careful not to place your hands or fingers in even if it is not running. Worst case scenario the worm gear that rotates the larger auger is broken and jammed and needs replacement. If both augers move freely then you will have to remove the cover under the motor and inspect the belt drive mechanism.
The most common cause of this is the drive belt is worn or broken. Sometimes the drive cable stretches (from the handle to the trans) To check the belts and tension you remove the cover (usually plastic) in the middle of the snow thrower to look at the belts. Your operator's manual will show you how to remove the cover and check/change the belts. If you don't have a copy you can get the manual through managemyhome.com You will need the model number off the snowblower. It is usually located on the bottom right hand corner of the frame (from the handle side) The model number looks like 247.123456. The belt closest to the engine drives the transmission. With the engine not running, have someone depress the drive lever and check the 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 your Craftsman and most MTD made models through searspartsdirect.com or jackssmallengines.com. If you are unfamiliar with repairing machines you can get your MTD snow blower repaired by taking it to your local Sears. They will have a technician troubleshoot and repair the unit.

Your belts are grabbing, make sure they are loose when not holding clutch lever. Also make sure that the guide pins are close enough to hold the belt loose when not engaged, I have the same tiller I use now.tines cannot turn if belt is loose enough. Maybe you bought the wrong belts A verses V belt.
No brake down on gear box for auger, part #740013 and its DISCONTINUED, belt # 700035
