Torro snowblower won't throw snow. Gets stuck in auger and blades.

Amber. With machine on level surface,fill gear box with specified gear oil until it starts running out the fill hole on front of gear box.

Most snow blowers have "Shear Pins' that connect the blade to its drive shaft. These 'shear' off when hitting rocks or other debris that gets caught in the blade. Check those and by new Shear pins. If it is not that, then you have problems in the gear box, or shifting mechanisms.

It sounds like the auger always turning is the auger engagement handle/line/connections are not adjusted correctly. They/it is too tight causing the auger to engage before it should. It may be up at the handle where you loosen a jam nut, screw in or out a threaded shaft, and retighten the jam nut. (If you have ever adjusted a bicycle brake it is similar.) (I have a craftsman, made by MTD, and I think I saw MTD also list Ariens.) Or it could be an adjustment somewhere else (but I'm not sure where).

As far as one auger moving and the other not, you may have a shear-pin (shear bolt as the manual calls them) on each side of the auger's shaft (my craftsman has one on each side), and the one on the side that stops turning is sheared off. (It moves without snow present due to the driveshaft inside the outer auger shaft turning, but it won't turn under load (snow).) You may confirm a sheared-pin by turning the machine off and try to turn the auger blade. If it turns somewhat easily, that's a bad shear pin. Remove the old shear pin. If the old one is as long as the new one, that aint the problem. The shear pin in the image is one kind. Mine appear as a straight bolt (no grooves), threaded the entire length. You will have to rotate the auger blade until it aligns with the hole in the shaft. Use a nail that fits and rotate the blade until the nail goes in. Remove the nail and screw in the shear bolt:

The auger clutch control up at the handle looks like this:
From my manual
Auger Control

• To check the adjustment of the auger control, push forward the left hand clutch grip until the rubber bumper is compressed. There should be slack in the clutch cable.
• Release the clutch grip. The cable should be straight. Make certain you can depress the auger control grip against the left handle completely.
• If adjustment is necessary, loosen the hex jam nut and thread the cable in (for less slack) or out (for more slack). Recheck adjustment. Tighten the jam nut when correct adjustment is reached.

Here's another view of that:

I hope the above info helps you take care of both issues.

two things to do. One, get the carb service and have them check the governor.

Two, have the auger belt replaced.

I wonder if your cable has broken in half.

If I was you I would check key way to see if it has sheered off. It is in center of big drive pulley where belt goes on, Just remove nut and slide pulley off to check condition. Best to split snowblower in half. Your snowblower has two main pieces it will be 4 or 6 bolts to separate your machine.

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 will assume you are referring to the 2 stages in the front of the machine. The spiral auger rakes are the first stage, they are designed to collect the snow and feed it to the impeller. The impeller is the 2nd stage and is to throw the snow up the chute. The lower rakes in the front do nopt throw snow only collect it.

Check for another sheared shear pin.
