The lawn mower acts the same as it does when you try to engage the blades in reverse but I took the wire off to eliminate that item being related. It seems like it may be something with the safety wiring on the deck engagement, ie a short or something going to ground.
MY 2003 14AT809H misses out and back fires when I try to engage the cutting deck or when going uphill. Also, if I disengage the blades and try to reengage at low speed will miss out and try to back fire and die. I have tried to locate a wiring diagram on this mower to no avail. Any ides on what...
