MTD Electric PTO Cluctch Disengages

[geckoguy]

I have 2005 Huskee Supreme (MTD) Riding mower that the electric clutch started disengaing last May. At first it would disengaging after about 15-20 minutes, then re-engage it and it would stay in for about 10 minutes. It then quickly turned in to where it would not stay engaged. I replaced the electric clucth and still the same problem. I checked the fuse and it's good. I replaced the PTO switch, relay and ignition switch. Currently, it will engage for about 3 seconds and then disengages and that's just sitting still. I am thinking that there must be some type of circuit breaker in the wiring and it's tripping but I can not see one.

Any help will be greatly appreciated.
Thanks!!!

Since you have already replaced all the main components, Check ALL wire harness connectors/plugs for corrosion and a tight fit. A loose/corroded connection can make contact long enough to warm up with load applied then drop it.

how old is the battery? is it weak? might want to replace it. my dad had a john deere that did that but the battery was about shot once we replaced it problem went away.

Have you checked the Operator presence safety switch, probably underneath the seat, I'd go ahead and replace that.
