I have a near new Scag Cheetah with 27hp Kawasaki I got it out of my shop & mowed the yard. When I took it back to the shop I could not get off the seat without engine trying to die. I checked all the safety switches & they all seemed to work properly. Then it would not start. I checked the PTO switch after talking to another Scag Cheetah owner. He said he had replaced the PTO switch 3 times so I took the switch off & took it to my dealer. He gave me a switch that supersedes the one I had.
It is a Delta Systems Inc kit #463034. Replacing it was easy & now everything works fine. If you own a Scag 60” you might want to save that part number. I believe it’s a better switch.
