Small Engines (Lawn Mowers, etc.)/Craftsman electric lawnmower model 900.370510


I was mowing tall grass and mower quit. I cleaned out all the grass from the mower deck underneath and anywhere I saw grass but it still won't start. The breaker is not tripped in the house so I know it's not that. What else can I do to get it started?

It is possible the rectifier failed due to excess load or just old age.

Do you have a volt meter and are you familar with testing electricity?

We find a lot of failures with the on/off lever on the upper handle.  Often times the parts inside will wear or break preventing the switch from actually turning on.

We have a small fix for the lever issue that involves a small metal pin and drilling a hole.

Did you check You Tube for videos on fixing or testing electric lawnmowers?  There is a lot of information on You Tube.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
