Before you start removing covers and panels unplug the mower. Turn the mower over and carefully try to spin the blade by hand. Your checking to where the issue is most likely to be.
Does the motor sound different when you pull the Start trigger? If it sounds a lot faster than normal, it could be an issue between the motor and gearbox.
Does the blade spin really easily and feel like it's not bolted down? Does the blade not turn at all like it's 'locked' or 'jammed'?
- A loose or floppy blade is commonly the centre mount bolt for the blade is loose or the blade isn't seated correctly.
- A 'locked' blade could be a gearbox or a motor issue.
Take off the black plastic hood (4 screws), clean debris and check connections to, and condition of, shunted brushes. They're available from B&D parts for a few bucks.
Two things come to mind. The brushes in the motor should be replaced. (Get them at a local motor repair shop, but take one of them in with you to get the correct one). If that is not the problem it may be the switch in the handle that you turn it on and off with. The switch may be corroded or bent. Good luck...Lee
Sounds as though you either broke or badly damaged the flywheel key. It is located on the shaft that comes up through the flywheel. If you have ever taken the cowling off, you know how. Just make sure to use the proper size and shape flywheel key. This key is designed to break in order to save the more valuable parts of the machine. Good luck...Lee
