NSV...NOT!
So last summer I had a service call on my riding lawn mower. Guy came out fixed it. It never worked after that....each time I engaged the blades, it died. Well, I have hired a lawn service and just didn't worry about it.
Fast forward, to now...I am tired of paying the lawn service, so I set up a service appointment to resolve the dying lawn tractor issue. So the guy comes out and it works just fine, no problem whatsoever. He then tells me to get on and give it a whirl, it dies.
Conclusion, when I lean forward to reach the lever to engage the blade, it shifts my weight enough that the "kill switch" that requires weight on the seat is flipping. Basically, I do not weigh enough to run the darn thing.
