Hi,

My son hit a short stump this weekend on our Troybilt 42in Pony. It stopped the blades and shut the mower down. Now when I try to start it I get nothing, no clicking from from the starter, no hint of the engine trying to turn. The only thing I can compare it to is when you try to start it with the PTO engaged and you get the same "nothing". Is it possible that there's a PTO safety switch somewhere that was damaged or that it stretched the cable out too much (it does seem like there's a little more play when the lever is in the disengaged position)? Please tell me that he didn't wreck the engine!

Thank you,

Dustin

ds, I'm sure you will get help on this...but have you looked to see if a blade is bent or debris is locking up the engine? Once it turns again you may have to look at the flywheel key.

Yes, one blade was bent. I could move both with my hands (although the bent one had more resistance than the other). I removed the bent one just in case it would not clear anything. Still no luck getting it turn turn over.

Thanks!

Ok when you engage the blades the handle moves a safety switch. When you move the lever to off it should push on the switch. Follow the lever down and you will find the switch. If it did not come unplugged or cut a wire. You can just bend it so it will make contact with the pto lever.

Thanks, I'll try this tonight.

Also check 20 amp in line fuse between starter and solenoid and see if it is blown.

Flywheel key is broken and or pto clutch key is broken.

So I checked the solenoid, PTO and brake safety switches and the 20amp fuse. All are good. My question now is, if it were the flywheel key or PTO clutch key, wouldn't the engine still try to turn over? I get nothing at all, like trying to start it with no battery hooked up (and yes the battery is good).

Hit stump, mower stopped dead, now can't start
I have posted possibilities, take your time inspecting all electrical connections, hands on, battery, ignition switch harness backside of dash, checking to make sure everything is tight and secure.

Thanks for all the help. The problem turned out to be a short in a wire leading to the brake safety switch. Looks like it was pinched, perhaps when the deck was pushed up by the stump?
