Have a craftsmand 24" snowthrower
If the motor runs well, the two most common causes of this are the drive belt is worn and/or the shear pins are broke.
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.
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 blower assembly drives the auger/blower and the belt closest to the engine drives the transmission. It sounds like you need to inspect the blower belt.
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.
Replace the belt if it is worn, stretched or frayed
The shear pins are located on the auger in the front of the machine. Your newer Craftsman has four. If you don't now about them look in your operator's manual for the location. You need all four for the snowblower to work well. Replace the missing ones.
You can get parts for you Craftsman and most MTD made models through searspartsdirect.com. With other makes you can get parts through jackssmallengines.com
If you are unfamiliar with repairing machines you can get your snow blower repaired by taking it to your local Sears.
They will have a technician troubleshoot and repair the unit.
