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

My son was mowing the lawn and he heard somrthing start to gride up so he ran away from the mower. When he tried to start it again it wouldn't. When you pull the starting rope the flywheel and blade just keep spinning like their not making contact with anything else. What could cause there not to be any engagement with the motor?
