I was mowing on my JD 445 when I hit a stump with the front of the mower deck. The tractor immediately cut off! I disengaged the blades and then tried to start it. It is dead as a door nail. My husband checked the battery cables/fuse. All OK. What could have happened?
Thank you!

Under the seat there is a safety switch that cuts the power if you would fall off, etc. Try unplugging it and replugging and or replacing it.

I have a John Deere LA125. I bought it new in 2009. After sitting unused in the garage for the winter (5 months) I couldn't get get it to run. The engine wouldn't turn. There was either a clicking sound when turning the key or no sound at all. I changed the spark plug - nothing. I boosted the battery and it ran. I was able to cut the lawn then turned it off. A few minutes later, I tried to start it and it wouldn't start again. I have to boost the battery each time. Any ideas?

I bought a brand new John Deere LA120. After a few uses it would not start or I would get a click sound or it would just turn over once or twice then nothing. I thought it was the battery or an open ground causing the problem.

A newer high amp battery may not change anything. I carefully checked out all the wiring. Nothing. I asked a dealer. He said it was the valves out of alignment. I thought he was crazy. I checked with a second dealer and he said the same thing. He said they could adjust the valves but I would be back next year with the same problem.

His suggestion was to rotate the air intake counter clockwise that sat on top of the engine until I felt resistance then it should start. I rotated the air intake as he suggested and could feel the resistance and hear the cylinders and valves moving. Then it started right up. So that is how I have to start the thing every time.

Sometimes I have to turn the air intake clockwise for it to start. The air cleaner is the screen disc that sits on top of the engine and rotates when the engine is running

My D130 has a new battery and it will crank, but won't start. I checked the air filter and it isn't bad. When I pulled the spark plugs they were clean and wet with gas. I don't know what else to check.

Best Answer

Plugs are not supposed to be wet with gas...Either too much fuel is coming out, or no spark. Check your fuel filter and the gaps on your plugs.

There is a safety switch under the seat that stops the machine from being started unless someone is sitting on it. It may be disabled. Check that first.

Thank you but the problem ended up being a bad connection with the positive battery cable. The lights not working pointed to that or the key. Thanks, all is well

Here are a few things that can cause the tractor to not start.

  1. Inspect your spark plugs for signs of wear and tear. The spark plug is what ignites the air mixture and fuel in the engine's cylinder to start the tractor.
  2. You could have old or bad gas in your engine. If you have left gas in the engine it could evaporate and leave a thick substance in your engine that can clog your engine. The old gas can clog the carburetor and your engine won't strt.
  3. The last problem could be a clogged fuel filter. This also happens from bad or dirty gas.
  4. Before replacing any of these parts rain the old fuel from your fuel tank and replace it with new fuel.

I have a John Deere ride on mower. The other day I got off the seat without putting it on park and it shut off and won't start. It turns over and has battery power, but won't run. It did that before and it started after a few days. What can I do?

Not positive(no pun intended) about tractors but ignition and computer problems where nothing is broken can many times be solved by resetting the computer system(even a rudimentary one such as the ignition chip). Most cars you can do this by crossing the battery wires. I would have said check fuses until you said it happened before and self corrected. Almost certain it just needs a computer reset. Online manuel of manuf. site would also tell you how to do it. there is usually more than one way, crossing the wires is universal. Good luck! Peace All.

Take a look at the ground wire - the same thing happened to my Sears Craftsman mower - somehow, the ground wire broke and the mower wouldn't start or even turn over. My son reconnected the ground wire and it's been running OK since then.

I read this advice online that might help you:

"In most cases a tractor only running with the choke pulled out indicates trash and/or contamination being present in the carburetor. If the fuel pump is failing it might would still run but only with the choke out. Normally it wouldn't run for very long like that though. With the tank being in the rear of the machine it is also possible that something has happened to the fuel hose. I would recommend inspecting the fuel hose to make sure it's not pinched or broken. A slight crack in the fuel line would have the same effect where pulling the choke out would cause it to run. Normally in that circumstance you would notice a gas leak though."

The site has a lot of suggestions and contributors. Check it out here:

I have a JD 120 with the same problem. This how the JD told me to start the machine. The valves are out of alignment so on top of the engine is a round screen that spins and cools the engine when it is running. Turn the screen counterclockwise until you feel resistance then start it. When I do this most of the time the machine will start.

Other times I have to turn the screen several times until resistance and other time I turn it clockwise. Either way it is a pain.Dealer told me the JD people use a cheap Briggs and Stratton engine and sell these units to the big box stores to be competitive with the other brands. Dealer told me I should have bought the 3000 series JD mowers. He also said he could fix the valves but I would be back next year with the same problem. Hope this helps.

I am using a snow blade on the front of my riding lawn mower. It will not start. I checked the battery with a multimeter. It's fine and registers 12 volts. I have 2 new spark plugs which I rechecked the gap and it looks good. There is plenty of gas. I apply the choke and immediately smell gas so I assume that gas is getting in OK.
