I'm inclined to look at the wiring in the PTO curcuit as the problem, not the clutch. If the switch was working properly, when you push the button it should shut off power to the clutch, releasing it. Something is send power to the clutch after the switch is opened. I think you replaced the switch, which would then lead me to tear open the wiring harness and follow each wire through each component, looking for nicks, cuts bad connections, etc. I know that this is not easy and a VOM or a voltage reading test light will help. Long slow tedious task. To tell you the truth, this is a problem I like to work on, because it makes you use every skill in the tool box to solve. Customers hate it, because they think there is a magic tool in my box, which will allow me to diagnosis the problem in 5 minutes. You best tool is make NO assumptions. Test and verify everything twice, don't forget the safety switches, then move on.

Not to hijack this thread but my issue with the Raptor SD is I pull up the PTO switch to engage, mower works fine for 10-15 minutes then blades stop turning. Up and down on PTO switch, no go. Problem just started at 65 hours. Tested PTO switch with ohm meter and shows good. Might switch out the two relays. I hate these wiring gremlins Rivets but give you a lot of credit for trying to help here. Stanley
Switched out my relays to no avail....as you probably read. The good part is - they aren't expensive. Good luck. I am hoping to get around to narrowing down my issues this coming weekend.
