Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

My neighbor, an old timer, got an Ariens ST8 24 from a fella he knows up in Maine. The motor runs fine but today during the big storm he was doing his driveway and it stopped throwing snow. We took it in the garage and observed the following. The auger turn and it pulls in the snow, but the impeller has no power. When it's off, the impeller just spins freely. Is there a shear pin or something or do we need to take the gearcase apart or???

Thanks
