Small Engines (Lawn Mowers, etc.)/pto clutch


I'm working on a Cub Cadet LT1046, Model 13AP11CH710, Serial 1E215H10284. On the Ignition Switch there is a position for Caution Children,& a Reverse Switch. & a Normal Run position. While mowing in the normal run position the PTO WILL CUT OFF. I can reset the PTO switch & it will come back on. It works fine in the Caution Children position. The headlights are on in both positions. I have bypassed the seat switch.
Any information would be a great help.
Thank You,

I would start by checking the PTO clutch resistance.  If you Google "Toro Electrical
Demystification Guide" you will find a PDF by Toro that contains a good description of electric PTO clutches.  It covers operation as well as troubleshooting.  The resistance values may be a little different than yours...but not by much as most home owner mowers use a 12 volt DC system.  If your clutch is bad the resistance values will usually be very low or very high and the fuse or circuit break will blow/trip.

Do you have a volt meter?

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.
