I have a dual stage snow blower (Craftsman model C950-52131-0) and the unit will not propel itself. I have checked the drive belt, the traction drive cable and the friction disc. They all seem to be ok. Any ideas on what the problem could be?
If the engine is running well, the blades are spinning yet the machine isn't moving, it may have a shear pin that cut off or the clutch isn't working properly. For the shear pin, look to see where the last part of the machine is turning with regard to the drive axle. A shear pin works like a nut and bolt would to attach a gear to a round shaft. It is just meant to break away to prevent damage. Mine has a belt drive from the engine to the gearbox and a chain drive from the gearbox to the drive axle (using a shear pin). For the clutch you need to investigate how the clutch works on that model. It should grab a spinning flywheel when engaged.
