I just mowed last week, but now it won't start. When I mowed last week the mower was low on gas, but I wanted to get as much done as I could. I ended up running out of gas and my paw paw had to help me get it to the building. We put it in neutral, pulled it with his fourwheeler, and pushed it into the building. Now this week I filled it with gas, went to start it, and it would not turn over. It tries to, but won't. I have no idea what could be wrong.

You might not have all the safety features engaged and that is why it won't start. Here is a troubleshooting guide from the company. http://www.cubc  revised_5_19.pdf

Have you tried to prime the carburetor?

This might be helpful, from ShopYourWay:

It's very possible that there was some trash/debris floating around in the fuel tank and when the engine ran out the stuff was sucked into the fuel line.


If you're sure the fuel lines are clean and debris free, you'll need to remove the bowl of the carburetor to clean it out. It's possible to have some trash/debris sitting in the bottom of the carb bowl that it stopping up the jets.

Normally in these circumstances it is fuel related problems causing trouble. It's also possible that you over primed or over choked when trying to re-start and flooded the engine. Take the spark plug out and see if it's wet. If it is, dry the plug off good and let it sit with the plug out for about an hour. Put the spark plug back in and see if you can start the mower.

Thanks, but I always check safety features first thing beside if it was it wouldn't have been doing anything at all. I was able to get a hold of my paw paw and we got it started. He said because I let it run out of gas I had to give it time for everything to prime.

What your Pawpaw told you was exactly what I'd have have told you to try first. I'm wondering if in doing so, that he showed you how to do it in the event it happens again?


I have owned mowers and other equipment that we had to Prime the carburetor every time we started it. If you aren't quite sure, you can look at your manual or even ask your pawpaw again.

I have a Cub Cadet riding lawn mower that won't start or turn over. It worked fine last week when I used it. What could the problem be?

The switch is under the seat. You can try disconnecting it and re-connecting it.

Here are a few things you can check:

  1. You need to start with the gas tank and your gas.
  2. If you've left gas in the tank when storing your mower sledge has formed in your tank.
  3. You'll have to clean the tank and add new gas.
  4. You'll also have to clean your carburetor and make sure there is no sludge in there.
  5. You will need to replace your spark plugs.
  6. If none of this helps please ask a few of the experts at this forum for advice: http://www.mytr  reel-mowers.html

I put the positive cable on negative terminal and put the negative on the positive by mistake. I reversed the cables and now they are on the right way. It will not start. What do I do next?

This can short out the starter or the solenoids on the mower. You'll need to take a volt meter and test your cables to make sure you are getting a good charge or reading to the starter and solenoids on the mower.

I replaced the starter solenoid and still get the clicking sound. The volt meter shows low voltage on the low voltage side. Anyone know the cause of this?

I have a commercial Cub Cadet recon Zero Turn and it won't start. When I turn the ignition it won't click, a few days ago it ran just fine then all of a sudden it won't even click. I've checked the plugs and battery and they are OK. Please give me some guidance.

The starter cord is locked on my Cub Cadet with Briggs & Stratton engine. I got one season of good mowing. This season it was hard to start and when I finally got it going it locked up after 1/2 of my large yard. I turned the mower off and on several times over the course of mowing the yard to dump grass and pick up dog poop.

Pulling cord was getting more and more difficult to pull. It would jerk and halt, but the mower would ultimately start. Then all of a sudden it wouldn't pull an inch. I took the cover off and removed the pulley unit. The pulley moves fine when removed, but flanges (?) come out and lock against ridges in the unit when mounted and the cord is pulled.

The gas is full, oil clean and full, and there is no grass impedance. The choke and hand lever seem to be functioning normally, but took fussing with them to start the first time. Now nothing will unlock the cord because pulling engages the metal "wings" on the pulley unit and they lock against metal notches in the mounting cylinder.

Cub Cadet Mower Won't Start

Take it back to where you got it or to a shop, good luck. (04/14/2010)

Cub Cadet Mower Won't Start

I asked my hubby and he said to take the spark plug out and then try to pull the rope. It should pull easy then. If it still doesn't, that means something is locked up. Try this, it might help. Or, as Hubby said, it might be a lot of other things. This is one idea to try. Hope it's the one! (04/14/2010)
