Request: Riding Mower Won't Start
Archived on 08/06/2009
I just replaced the fly wheel and the starter on my lawn tractor. I was able to start it briefly and then it cut out. I put a new spark plug in it and a new battery with no luck. It still won't start. When I try to start it, the engine turns like it wants to start but it doesn't. Any suggestions? I don't know what the problem could be.

My husband says there's a little slot the flywheel fits in and it needs to be put it correctly. Check the flywheel again. (05/24/2009)

Did you check to see if air filter needs cleaning? Also, did you look underneath to see if twine or something is wrapped around the blades? (05/24/2009)

RE: Riding Mower Won't Start
Thanks for your help but I already did those things. I just don't know why it wont start. (05/24/2009)

My daughter had a mower that wouldn't start and she found out it was the carburetor. So she bought a kit and rebuilt it herself. (05/25/2009)

Check the fuel line and maybe a new fuel filter. (05/29/2009)

Hi. What you do is spray a shot of starting fluid into the carb and try to start. If it runs and dies you have a fuel problem, if it does not fire or start you have an electrical problem. Then you know which way to go to troubleshoot. Let us know. Hope this helps. (06/08/2009)

I have a lawn tractor with a basic starting problem. When I turn the key in the ignition I hear a click, but the engine won't crank up. I have removed the fuse and there is no click when I turn the key. I am assuming that there is power running to the ignition switch. The fuse test proves this. Is my problem likely to be the ignition switch or the starter motor (if such a thing exists on a lawn tractor)?

I bought a battery charger for 40 bucks at an automotive store. Whenever my mower doesn't start it is because the battery is low or dead. I hook up the charger start the mower then disconnect the charger. If you want to charge the battery before you use your mower Sears has a battery charger for 50 bucks that shuts off when the battery is charged. (02/24/2009)

Take your battery to a local automotive store and have them check it. Chances are it needs to be replaced and that will solve your problem. Marylee (02/25/2009)

What the thieves at John Deere won't tell you is to check your relay (it is under the seat on the STX 38). Over the years, because they believe in making money over serving their customers they have sold me a starter, two ignitions, and a coil module, because I would not bring my tractor in for them to fix it. It is a part of the ignition/starting system that commonly fails and only costs fifteen dollars. Pass this on. (05/05/2009)

My riding lawnmower won't turn over. When I pull the spark plug it tries to turn over, when I put it back in, it won't. Verified spark with plug removed. Not sure where to go or what's wrong? It's a Briggs and Stratton 18hp engine.

My husband suggests it may be a weak battery or a weak starter. (05/05/2008)

RE: Riding Mower Won't Start
Greg, it sounds like it has enough to almost turn it over when the plugs out because the compression is lowered meaning less resistance and when it's in then there is full compression. Sounds like something is too weak, I'd start with the battery making sure the terminals are clean and the battery has water and is charged. (05/06/2008)

You mention something on thrifty fun about the ELECTRONIC MODULE. I seem to have that problem. Power craft by Briggs and Stratton will start and run but when I cut it off to dump the grass it will not restart until it cools down. So when you mention the problem on the forum it sounds like that is my problem.
I do not know where and how to get a quote on the electronic module for my riding mower. If you could help, please let me know. Thank you for any help you can provide. Meng (07/15/2008)

RE: Riding Mower Won't Start
I have a Husqvarna with a Kawasaki 15HP twin cam engine. It was only used for 1 summer. It won't start, it would just spin. So I replaced the spark plugs and checked the battery. All good. Then someone told me to spray starting fluid into the air cleaner. When I do that it fires right up and runs until that fluid is used up. After all of this I would have to think it is the carburetor. It was all gunked up, so I bought a new one. Threw that on today and it does the same thing. I checked the carburetor and it is getting fuel in there. So what can it possibly be? If it fires up with starting fluid then spark and engine is definitely good. And it is pumping fuel, so I doubt the fuel pump is bad. (07/21/2008)

Meng, your description of your fault describes mine exactly. My ride-on mower has a 13.5 hp B and S Invek engine. It has magnetron electronic ignition. Just 2 yrs old. So, what have you done and replaced to get your mower going again?
Thanks in anticipation of your reply.

I have a John Deere STX 38 riding lawn mower that I can't get to start. It ran fine all last summer, but unfortunately, I left it outside in the winter. I changed the battery, spark plug and wire but nothing. The motor just spins. It doesn't look like I'm getting any spark in the plug wire at all. Someone said one of the cylinders might be stuck, but I'm not sure. Any help would be appreciated.

Update on my Husqvarna LR125 rider that wouldn't start/stay running. The dealer finally found that the "electronic module" that provides spark to the plug would break down after about a minute of run time and then would not provide sufficient spark to keep the mower running or to restart it until it cooled off. Still waiting on the part.
This was the part that Kohler listed as, "hardly ever goes bad so look for other problems". (04/28/2008)

RE: Riding Mower Won't Start
On some mowers they have a shear pin on the bottom shaft that is designed to break to prevent damage to the main shaft check that, if its broken just replace.
The lack of spark could be a number of things if it is electronic ignition then the main control box has probably died if its an older model it will be likely be the condenser as these do pack up due to moisture. There is always a possibility that the spark is tracking or shorting so just check all leads there also may be water in the petrol tank or carby as that will cause a motor to die but you would normally have spark.The lack of spark seems to be the main issue in this case. brentnz (04/29/2008)

My Husqvarna lr125 riding mower won't start. The batteries good, all safety switches bypassed, and new solenoid. It clicks when ignition is turned (same as before new solenoid). It starts when jumped from battery direct to starter. Runs maybe a minute before stopping. Any suggestions? Thanks!

Check wiring and continuity with a volt meter and make sure its grounded and isn't corroded. (04/04/2008)

RE: Riding Mower Won't Start
Thanks for the suggestions!
The battery is new and terminals are good and clean and continuity is good.
What puzzles me is that it will start (by by passing everything) but only run for about 1 minute before it dies. When it dies it is an "electrical" kind of death rather than a "starved for gas" death.
It makes me think that something is heating up and then not working? (04/04/2008)

RE: Riding Mower Won't Start
I'm having basically the same issue, in so far as the click but won't start. I have charged the battery. The terminals are clean. I would love to hear what fixed your problem. Frank

RE: Riding Mower Won't Start
I'll let you know Frank. I broke down and hauled it to the local Husqvarna certified repair shop. At this point they are stumped. I replaced the switch, solenoid, bypassed the 3 safety switches, replaced the fuse so that was about the extent of my parts swapping. It will be interesting to see what it was. (04/19/2008)

My riding mower's engine just spins. All of the belts are ok. I was using it when a loud pop happened. After that, when I tried to restart it, the motor just spun as if something in the engine broke. Any suggestions?

It sounds like you might have broke the shaft since the blades aren't working but the motor is spinning.. (10/01/2004)

RE: Riding Mower Won't Start
If mower won't start, check your battery posts. I find them a bit cantankerous on these small batteries. Usually the neg. is at fault. Be sure the charge is up. If not don't charge at 10amps, but 2 amps. (03/01/2008)
