I have a 4/2006 Troy-Bilt Pony with 17.5hp BS and 42 inch mower deck. I am having trouble starting it consistently it seems to be intermittent. Not even a clicking! I have replaced everything in starting system, solenoid, battery, fuse, starter, ignition switch. Only thing left I can think of is a safety switch. So my question is, " WHERE ARE ALL THE SAFETY SWITCHES ON MY MOWER?"

Hi,
Most are behind the engine on the left side beneath the dash. Do check your engine ground first(engine mount bolts loose) as they will do what you are saying.
Peace,
Clarke
