Re: Wheel Horse 518-H PTO Engaged Engine Dying
Did some tinkering with it last night, I disconnected the seat and the PTO switch, cleaned each one out and tried a few things out, still not working properly. I tried out engaging the PTO and standing up, the engine cuts off as it should. I can run the mower deck for about 3-5 minutes before the engine starts to want to die out and even after disengaging the PTO the engine still wants to die no matter if I throttle down or up or anything, no matter what the engine will die on me but after the engine dies I can start it back up with one crank and then the same thing happens all over again if I try to engage the PTO.
This is a manual PTO with the lever on the side and I just replaced the mower blades and the PTO belt so everything is good and tight, I also cleaned out the deck and greased the spindles, everything was spinning free when I put the deck back on. If there was strain on the engine wouldn't that be apparent immediatley when you engage the mower? Everything sounds and feels good when the deck is engaged.
Is there any good way to test the coil to see if it is at fault? Also, how easy/difficult is a new coil to come by? The engine runs fine, I can drive the tractor around with no problem but like you said by loading the engine with that mower deck engaged it wouldn't take too long for it to get hot.
The only other thing is a pesky parking brake light that is on even though the parking brake is not engaged and a flashing oil pressure light even though the oil checks out fine, any tips on a remedy to those?
I appreciate all of the help!
