My mower just clicks when you turn the switch on. It has a new battery and belts. It only stated for a few seconds and died. Now all it does is click when you try to crank it.
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.
The ignition switch won't start the engine for my 12 hp Ranch King riding mower.
I was going to say, cleaning battery terminals and even making sure that the batteries are regularly maintained - some need water levels checked and added - can cure most of these sorts of problems
My brother has an old riding mower (90s I think) that won't start. He put in fresh gas, a new battery, and fresh oil, but the engine won't start. He says it's just making a click, the motor shakes, but nothing happens.
The switch is under the seat. Disconnect it and reconnect it.
How about the spark plugs?
new spark plugs? Does the carb have old fuel in it?
Clean out the carburetor and it should do the trick
I have had pretty good luck cleaning the carburetor. Then if it still doesn't start up, add some fuel cleaner to the tank.
I was cutting the grass. I got off my Snapper rider to pick up trash. The mower died and won't start back up. It is like a dead battery, but the battery is good. Could it be the solenoid?
I have a Scott's riding mower with a 17Hp Briggs and Stratton motor. It won't turn over after mowing the grass last week. It needed a new battery and air filter. There is gas or oil in the air filter and it back fires out of the air filter, with fames an all. Any help? I changed the plugs and oil before storing it this winter.
Is there some sort of starter relay underneath the seat?
If your engine uses breaker-point ignition, then your points might have fallen out of alignment. Check to see that they are properly in place.
The switch is under the seat. Try disconnecting it and reconnecting it.
Thanks. Yes tried the switch under the seat. I ended up droping off at a friend's shop. Hopefully find out why.
I was mowing and the mower shut off. It still had plenty of gas. I changed the fuses, but all the engine did was click. The battery is fully charged. I crossed the posts on the solenoid with pliers, the engine cranked, but when I turn with the key there is only clicking.
It could be one of the safety switches in either the brake or the seat.
we had this problem and it was the fuel injector for us
Check the oil and make sure it doeset have gas mixed in oil also pull spark plug to make sure cylinder isn't full of gasoline causing it to stop piston from moving
I was mowing and stopped to move something and I killed it. When I got back on it wouldn't even turn over.
I have zero turn Z4200 riding mower and this particular day I was mowing and the mower lost power and stopped running and I tried to restart again, but wouldn't even crank over. I used a screw driver on the solenoid and it would turn over with very minimal power. I took the spark plug off and cranked it over and had a good spark and good compression as well, but when I placed my finger on the spark plug hole the compression was not enough compression to push my finger off the spark plug hole. With my finger still on spark plug hole I used a screw driver on the solenoid with my finger on the spark plug hole it has no power to push my finger off the spark plug hole.
Do I need power out of both posts on my solenoid for my mower to crank over?
I just recently cleaned out the carby on a 13hp Briggs and Stratton ride on and tipped the mower on its side to sharpen the blades, (spark plug on higher side). A fair bit of oil went through the carby, but I cleaned it out well. I put everything back together and it does the 1 click when turning it on, but won't even turn over? Can anyone help me out please?
I have a D130 John Deere tractor. The engine starts for me 220 lbs, but not for someone 150 lbs. I can start it, they get on and can't. I get back on starts no problem. Could it be the seat interlock switch? and if so what do I do to repair it?
My mower won't fire even though I put a new plug in.
I have a Castle Garden rideon mower. I only had it running a couple of months ago (cut the garden), it was sitting up in the garage since then, now it won't start. The lights come on, everything seems OK, but it just won't start. The orange light beside the red button to get the blades cutting came on. Any help or ideas please.
Check the battery. Probaly low on juice.Use a trickle charger for a day.
Its grand, fixed it,was a safety issue,plug underneath came undone, was to do with the gears,safety connector to engine,saying it was in gear when wasn't,simple to fix,just plugged it back in
Thank you for letting us know you found your problem.
I would just like to add that so many people do not "winterize" their mowers properly and then have many problems when "cutting time" comes around.
Just in case you need information on storing your mower properly, I have gathered some easy to follow instructions. I believe if someone does nothing else, just adding a fuel stabilizer would save them countless problems (and money).
I have a Yard Machine riding lawnmower that won't start. It has good gas and the oil is good. So id the battery. It turns over strong. The only way to get it to fire off is to either pour gas in the intake or cover the intake to restrict the air from intake, but it will die as soon it it fires off. Fuel is in carb bowl and it's been cleaned.
Mower won't turn over after cutting.
My riding mower won't start. It has fuel, a new plug, fire, turns over, new coil, and fuses. It ran great, sputtered, and shut off. It has new fuel filter. The fuel runs to the carb, no clogs.
I have a Morrison mini rider. I can not seem to work out how to free push it. It is in neutral.
I have a older Yard Machine riding lawn mower that has been sitting for a couple years. First of all I can't seem to get it into neutral to push it, second of all when I do try to start it it's tries to turn over, but it is with the deck engaged and I can't get the deck to turn off to get it started. Any help would be greatly appreciated. Thank you.
If it's been sitting for so long you need to empty its gas and clean the carburetor
From SF Gates:
Check the oil before you start a four-cycle mower that has been sitting for a long time. You may have neglected to replenish it the last time you used the mower.
Prime the engine by pushing the priming bulb three times. You should see fuel in the glass window behind the bulb. If your engine has a choke, turn it on. Try starting the engine. Turn the choke off after a few attempts and try again.
Give the spark plug wire a little tug to see if it's loose. If it is, push it onto the plug and try starting the mower. If there isn't any difference, remove the plug with a spark plug wrench and clean the gap with an emory board. If the plug looks worn, replace it with a new one.
Siphon the gas out of the tank with a siphon hose if changing or cleaning the plug has no effect. Store the gas in an approved container and take it to the local waste facility to dispose of it as hazardous waste. Pour new gas in the tank and reprime the engine. If the mower has a two-cycle engine, be sure to mix the gas with the proper amount of two-cycle oil.
Stop trying to start the engine whenever you notice the smell of gas becoming strong. That usually means the carburetor is flooded. Wait five minutes before trying again.
My lawnmower will not start. It doesn't make a sound. I have charged the battery and it reads over 12. I have done the ignition switch and spark plugs. I have replaced the solenoid and tried different wiring ways with it. I don't have any voltage drops to the starter. A couple wires were cut and I spliced them back together. Please help!
Is the fuel line open? Fresh fuel in the tank?
A couple of weeks ago while I was mowing the lawn with my 12.5 hp Yarkworks lawn tractor for some reason the machine started revving really fast. I turned off the ignition as quickly as I could. I then went to restart my tractor. However the machine would not turn over until it cooled down. The symptoms haven't changed. I can mow the grass for hours as long as I don't turn the machine off. Then I must wait until it cools down again. Someone told me I may have a warped head since the machine revved like it did. Help.
I changed the oil filter, added new oil, new carburator, new spark plug, new fuel filter, new battery, new air filter, and new gas, but it still will not start. The flywheel is turning over, the muffler puffs occasionally when I choke, but nothing happens. I am stumped. I poured a teaspoon of gas in the spark plug area to see if there was fuel constraint which resulted in a few coughs through the muffler. What do I do next? any suggestions? Thank you!
could be that the switch under the seat is bad. it feels when you get out of the seat and shuts off the mower. you can bypass it with a short peace of wire
I have a MTD rider, 42 inch. It won't restart when hot. I replaced the ignition switch, solenoid, and coil. At first it starts right up. If I finish cutting the lawn and shut it off, then it won't restart. I need to wait until it cools down; then it starts.

This may help 50% of lawn mower starting issues! Try adding a gasoline additive to boost octane and clean fuel lines. There is a product made especially for small engines that cleans the gunk formed quickly in lines and moving parts from current low emission fuels. Where did we think the stuff goes that doesn't burn and doesn't go into the air? - It stays in our mower's engine causing moving parts and plastic fuel lines to bond together!
After forgetting to empty the mower engine over winter, I found nothing worked to get it started. My local small engine guru suggested adding a fuel stabilizer, octane booster and fuel line cleaner made for small engines to fresh gasoline (read directions). Try to turn over a few times to get fuel moving into lines, leave sitting for a few hours then try again to start. It smoked and coughed the first few times, but gradually improved greatly, now starting much easier. And re-starting easily after being turned off! I will remember to winterize this year.
Another tip: keep the housing around the mower blades cleaned of dried on grass.
Also, if you are cutting grass with deck significantly lowered, try to start mower in an area with very little grass. Blades that rotate when you are pulling a starter rope are hindered from turning by contact with heavy, thick grass, preventing easy starting.
