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

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.

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 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 1979 John Deere 112 riding mower. It is not getting a spark. I tried changing the plug, but it still won't fire.

Answers

October 1, 20170 found this helpful

A few things to check on your mower.

  1. You have changed the spark plug, but did you change the solenoid?
  2. Solenoids can go bad and need changing. If the mower has sat during the winter, it is a good idea to change this.
  3. If a new solenoid doesn't help, you will need to change the ignition switch.
  4. Check the 12V coming from the solenoid to see if you have a current running through.
  5. If not you will need to change the starter assist relay also.

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.

Why won't my tractor start? What is the spark plug gap for a John Deere L130?

By KCR from Pineville, KY

Answers

September 4, 20110 found this helpful

I have a John Deere LA120 with the same issues. The engine is a Briggs and Stratton with 43 hours of use. I use a Champion RC12YC gapped at .030 inches. The first year the machine started great but not so now. My machine also will not start by cranking.

So, I bought a battery booster at my local auto store to add cranking power. I also bought a new battery with more cranking power but neither helped very much. I called John Deere but they don't have a tech service. They just refer you to your local dealer for service.

I visited one dealer who told me the valves are out of alignment. I thought that was a lot of BS. I visited another dealer who told me the same story. He said valves need to be aligned but within a year you will have the same problem. He also said the engine for the LA series is a piece of junk. Briggs and Stratton hasn't made a good engine in 10 years. The LA series is a cheap machine that John Deere sells to the big box stores.

He would not take my machine in on a trade for the John Deere X series which he said was a much better machine. He did give me this advise to start the machine. Lift the hood and turn the intake screen counter clockwise until you feel resistance. It should start. I tried it and I was able to start the machine.

The last time I used the mower it would not start turning the screen counter-clock wise, so I turn it clock wise and it started. The screen is the big circular screen with all the slots in it that sits on top of the engine. When the engine is running the screen is also turning at engine speed. Hope this helps.

The starter motor gear will not engage the flywheel when the key is turned to the start position. The gear hits the bottom of the flywheel. The motor cannot turn because the battery voltage has not been applied to the starter motor via the solenoid because the flywheel limits the solenoid travel. Releasing the key drops the starter motor gear back down and the gear turns counterclockwise a very small amount. The starter motor needs to be "bumped" as many as 15 times before the starter motor gear will mesh into the flywheel starting the engine.

I have about a 3 year old John Deere model 115, with a 19 HP B and S engine. It started to lose power going up my hills and then died. It would restart and run a little longer and do the same thing. I had the carburetor worked on and it worked a little better for a short time and now is worse.

It went from running to not starting. The spark is good. It is just not getting gas. If I manually push gas into the bowl it will start and run. I replaced the fuel pump to no avail. It will still not start and is getting no fuel. All the hoses to the fuel pump are fine. The gas cap's vents are open. If the valves are out of adjustment could this cause the engine vacuum to be too low to actuate the fuel pump?

I can get it to start by directly jumping the starter with the battery, but that's the only way. It seems to me that the battery, the starter, and the solenoid are all good. I am stumped. The only mobile John Deere repair within 200 miles closed, so I have to rent a trailer and drive it an hour away! So much for my warranty.
