Question: John Deere Ride On Mower Won't Start

I took my mower out of the garage yesterday, it wouldn't start because the battery was down so I had to boost it. I started the mower and put it on slow idle to let the battery charge. I went about my business while the battery was charging and all of a sudden I heard this loud exhaust noise like the muffler had fallen off the mower. I rushed to the mower and shut it off. I checked the exhaust and everything was fine. The problem is now it won't start and when I am trying to start it there sounds like there is an exhaust problem. This is a new mower I bought three years ago, 30 hrs on it.

Question: Riding Mower Won't Start

My 21hp B&S Platinum Craft riding mower will not turn a full rotation. Battery (even jumped from truck), new starter--starter engages, but engine will not turn full rpm. It appears to stop in compression, when engine is at exhaust position (?); starter turns flywheel maybe 1 to 1 1/2 rpm, then stops. It appears too much resistance to turn flywheel. Possible cause?

Question: John Deere Riding Mower Won't Start

I have a JD 18 HP. V twin; it's a Kawasaki engine. It has spark at the spark plugs and it's getting gas into the carb and to the spark plugs. It will crank over, but will not start and run. I drained the gas and put new gas in it and it still will not run, just will crank over. The battery and all are in great condition. What can I do next?Please I need help ASAP. I can't take it to the dealer cause of what they charge to fix stuff. It's a 2005 or 2006 model. Here are some of the numbers I took off it, FH580VBS04-R, FH580VA94857, and KAXS.686N40B. It has been sitting unused for about 4 or 5 years, but like I said I have changed everything and cleaned out everything also. It just won't run!

Question: Poulan Riding Lawn Mower Won't Start

My Poulan (18Hp Briggs) riding lawn mower won't start. I changed the oil and filter, however I did not fill up the oil to required amount, as mower was on a slight incline. I added 1/2 quart and it started very well. Put into gear and started to move mower to level ground.

Then the sound came! Like I dropped a tool into the engine. I stopped the mower and checked the dip stick. There was no oil level and white smoke. I forgot that filter was dry and that any oil put into engine would go directly to filter. There is no real resistance when I turn flywheel - after each revolution there's a clunking sound. What have I done :( Can I salvage it? What are my next steps?

Hello there, I'm sorry to say I don't have a cure for you but I'm in the same boat. Originally when I first started to figure out why it didn't start it was a funny thing. I put an inline spark tester and crank it over and it seemed to have spark but when I just tried a new plug and laid it close to block or head and it had little to no spark.

So I took and replaced the coil which is also know as a ignition module or a magneto and after looking on u-tube for gap etc. It fired right up so I figured I fixed the problem.

Well the next week I decided to replace the drive belt and after completing that (which was no fun), I tried to start and after checking all the possibilities of something I possibly might have do it ended up to have the same symptoms and it points to the coil being bad again. So I'm going to write information down on paper this time so I know what readings I'm getting before, after with both the bad one and the new one.

In all my years of being an auto mechanic I worked on many small engines that have your basic coil/magneto that sits on side of most all of them and they all serve the same purpose. to create spark from magnetic rector wheels that when the flywheel turns around it meets the magneto and sparks the plug. It's fairly basic and generally easy to diagnose but like you it sounds like we have the same issue.

Right now I don't have an answer but I will find out and I'll let you know what I came up with. it's probably something to do with a power or ground issue. 7 out of ten times that ends up being the cause. Take care.

By Starzilla02/27/2014

The fact that it just "clicks" when you try to turn it over may mean that the engine has seized up. Lack of oil mixed in the gas could lead to this. Also, you may want to try to replace the carburetor. Plenty of "How-to" sites on Utube and choose a reputable online business for mower parts and they should allow you to return carburetor if that is not the problem.

I tried starting my riding mower and it would not start. It sounded like the starter, so I replaced the starter. It started right up, but the next time I went out to mow the grass the mower would not start.

So I replaced the new starter with another new starter (not rebuilt) again it started right up.

Remove the spark plug and check a carbon build up. If found clean the plug. Check and rest the plug gap as required. Check for the smell of gas in the combustion chamber. If there is a strong smell of gas, leave the plug out until the gas Oder goes away.

Good luck.

By Dharris from TN

Question: Problem Starting John Deere X320 Riding Mower

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.

Question: Craftsman Riding Lawnmower Won't Start

I have a Craftsman Lawn Tracker model no. 917.28910. It is only about 4 years old. I have a problem starting it. I changed the battery and it will start on a dime. I will mow the lawn, clean it up, let is sit for a while, and try to start it up again to put it away and it won't start. It will click and sometimes if I hold the key to start a little longer than usual, it will turn over and start. Most of the time it won't do that either. Is there something that charges the battery while it is running such as an alternator? It seems after it starts and runs, the battery drains to a point that it won't have enough juice to start up. I changed the spark plug and no help there. Checked all the wiring and nothing is loose or corroded. Any help or ideas on what to do?

Question: Toro LX500 Won't Start

Do I need a new starter? I will gladly try any suggestion that someone has.

Question: 18.5 Twin Cylinder Intek Briggs and Stratton Won't Start

I have a twin cylinder 18.5 horsepower intek turbo cooled Briggs and Stratton engine on my Craftsman riding lawn mower. This is what happened and what I've done, I was finished mowing my lawn and tried to disengage the blades, but they didn't disengage, they just kept spinning, I noticed a spot I wanted to go over again so I started to drive in the direction without re-engaging the lever for the blades since they were already spinning with the lever down. All of the sudden I heard the engine not sounding right, it was a clanking noise so I shut the engine down right away. I checked the oil and it was a little less than a quart low, there was still oil on the dipstick. I tried starting it and it would not start.

This is what I've done, checked compression, a little low at 60 psi, but I read that it holds 70, also read that there is a compression release so you could have false readings. Either way there was compression. Checked for spark, changed plugs for the heck of it, gas was getting to the carb so the fuel pump is good, replaced the fuel filter, juiced the battery, adjusted the valves, added the oil it needed, drained and replaced the gas, went as far as spraying starter fluid in the intake and the cylinders! All of this and still it will not start. The engine turns and sounds fine, but will not fully start, not even a backfire, almost like I want to push on the pedal and give it some damn gas! The flywheel key is fine, I can hear my solenoid working, not sure if there are any safeties that still spin the flywheel, that's the only thing left that I could think of. Can anyone help me out? Thanks.

Question: Simplicity 7117 Garden Tractor Won't Start

This year was the same until yesterday when it wouldn't start at all.

I figured the battery had finally had enough so I pulled it out to get a new one and found a mouse nest behind the battery around all the wires. I removed the nest expecting to find chewed wires, but did not. I put the battery back in and the tractor jump started right up, ran for about 20 minutes, shut off and would not restart, jumped or otherwise. So I replaced the battery today and still nothing and I mean nothing not even a click.

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 have a Toro riding mower. The battery is OK. It had a loose connection which had interfered with getting power to the solenoid. I wriggled the wire a bit and the solenoid began clicking. After a few tries the starter engaged briefly (a second) and disengaged immediately.

Is the starter motor connected directly from the solenoid to the starter motor? Could the loose connection which stopped the solenoid operating cause the starter problem as well?

The gear from that "generator-looking" item is under a small cover and when I took a look the small gear was disengaged from the fly-wheel.

Maybe a better explanation of my situation will help. 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.

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.

Take the spark plug wire, pull it out of the sleeve, and press it to the frame. Turn the ignition. If it sparks, you have spark, your plug is bad. If not, your magnet isn't making contact.

I have a riding mower that won't start. It acts like it wants to, but won't. I shot some starting fluid in it and it will start for a few seconds then dies again. Any suggestions?

If the mower wants to start or starts with a shot of starting fluid, sounds like it is starved for gas. I would check out the gas line from the tank to the carb. May be a clog some where.

Well if the mower worked prior to replacing the gas line I suspect something wrong with the gas line. Could it be plugged, or have a kink in the line?
I would first see if gas is getting to the cylinder or in to the carb.
I think the gas is fed to the carb by gravity so there may be a air block in the line.
Iwould disconnect the gas line at the carb and see if gas is coming out the end of the line.

Question: Mower With a Briggs & Stratton Engine Won't Start

I have a Briggs and Stratton 12hp engine in my ride on mower that will not start. I have replaced the battery and starter, and have cleaned the carburetor. The engine turns over slowly as if the battery is low on charge (although I have charged it up) and there is a good spark at the plug. I have tried jump leads off the car, but it does not help. Any ideas?

Question: Briggs and Stratton Engine Not Sparking

I have a Briggs and Stratton T1600 Twin engine on a riding mower. The mower is going okay. I replaced a newish coil with an older spare to see if it was working. There was no spark. I replaced it with a good coil, still no spark. I tried magnets on the flywheel VG, coil gaps 0.005 to 0.010" between coil "horns" and flywheel. I disconnected the coil earth lead to the switch and there was no spark. Any ideas please.

I had the same problem this spring. Check to make sure the brake engaged, the key is in start position and throttle is set to choke. If this does not work, be sure the air filter is clean - you can wash it but be sure it is completely dry. If it still does not start, check the relay module. I opened mine, be careful when you pry the module apart, cleaned the dust off the contacts, replaced the two parts and the engine started after several pulls. It is also a good idea to drain the gas out of the tank after your last mowing of the year. I always drain my tank and change the oil before putting the mower to bed. Hope this helps.

Question: Toro Riding Lawn Mower Won't Start

I have a Toro Wheel Horse riding mower. I started it and pulled the choke up all the way really fast and now it will not start at all. I have replaced the battery but when I tried to start it, it just smoked. Then I thought it was flooded so I took the spark plug out and put it back in and then it just did not make any noise. Now I am trying to find out what is wrong with it.

If it smoked when you turned the key on and now nothing at all you'll probably find a blown 12 system fuse hid somewhere where you cant see it. if it is a blown fuse you have a direct short on the 12 volt line somewhere. When you find your short your mower will probably be fine then. Hope I could help if you need help finding the short list what model mower it is and ill try to find schematics for it on line and maybe make a couple suggestions.

Question: Powercraft Riding Lawnmower Won't Start

I am trying to fix my MTD/Powercraft riding mower. It has an 18 HP I/C B+S motor, twin cylinder. 42a707 series. It has a hydrostatic transmission. The starter will not turn the motor to start it. I have put on a brand new starter and it still will not turn the motor. Even when I jump past all of the switches and solenoids and jumper straight from the pos (+) battery terminal to the starter, the starter still will not turn the engine.

The battery is fully charged and tested so I have ruled that out. My question is could it be that the transmission belts/blade belts are too tight? Should the transmission belts be disengaged when trying to start somehow? Right now the belts are very tight all the time and the engine is VERY hard to turn, even by hand. I know it is not a compression problem, I have taken the spark plugs out and the problem persists.

It is not an OHV engine so I am not inclined to believe that it is a valve problem. Should the clutch be disengaging the transmission belt? What exactly does the clutch do on these machines? This may be a very vague question, but I have been fooling with this tractor for a week now and I am at my wits end. If more info is needed, or questions arise please let me know. Help me if you can! Thanks.

Well on my riding mower it has safety devices. One of which is the mower will not turn over unless I am sitting in the seat. If the mower is running and I leave the seat the mower will shut down. It is possible to over ride the safety device. If my battery is low I hook up my charger to the battery but I have to be in the seat for the mower to turn over. Once it starts I kick off the cables with my foot or have someone unhook the charger. I also use alligator clips instead of nuts and bolts to hook up the battery to the mower. makes it easier to disconnect the battery.

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)

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)

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)

By pebley

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)

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)

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.

RE: Riding Mower Won't Start

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)

By grumpy54

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 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.

RE: Riding Mower Won't Start

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

By Lorelei

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)
