    I have a CM274 mower and when I engage the PTO handle( just move the handle just a bit) the tractor tractor turns off. If I bypass the safety switch I can engage the PTO and the tractor does not shut off. The safety switch on the seat works fine as it should.
    I have replaced the diodes in the ciruit as well as the relays. The safety switch which turns on the PTO checks out as well.
    If I leave the switch bypassed you are able to start the tractor with the PTO engaged. But I do not feel comfortable in doing so
    Any Ideas?
