I have a Troy Bilt 46" cut 2015 model 13YX79T011 Horse . It seems dead, changed safety switch on brake/clutch on left side. Battery fully charged, changed ignition switch also. When I turn on the key nothing happens. Can someone please help? It all started when I had to change the steering rod and had to lay it on its side after draining gas, oil and remove the battery. It started just fine before removal of steering rod.
