Norm philo 4 #1 Posted December 26, 2017 I have a wheel horse 518-H with the mower deck and snow blower attachment. When I engage the pot for the snow blower the pot starts up and when fully engaged uhh t shuts off. I replaced the set switch but does the same thing. What else could it be?

littleredrider 408 #2 Posted December 27, 2017 There is another switch under the hood for the engagement lever, could be wires came off or out of adjustment. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,444 #3 Posted December 27, 2017 Is it the engine that shuts off when the pto is fully engaged? May be the seat switch. The idea behind that one is operator falls out of seat the engine stops. If you can provide a model and serial number we should be able to link you to a wiring diagram. This one may be the wrong one Garry 1 Share this post Link to post Share on other sites
