Cub Cadet Riding Lawn Mower Won't Start

April 4, 2021

I have a Cub Cadet XT1 18hp 42" Cut. Last season, it ran fine, this season I opened the garage to start it, with jumper cables in hand as I knew the battery would be dead, and new gas. I changed the gas out, drained the lines, drained the carb, and put in fresh, choked the engine, and turned it over. Wouldn't start.

Checked lines and filters again, everything seems to be in order there. Grabbed the plug wrench, checked for fire, and it has a healthy spark. But the plug was dry. Pulled the carb this time instead of just taking the bowl off to drain it, upon inspection of the carb and jets, everything is clean as a whistle. Slapped it back together, plugged in the little wire at the bottom of the carb, and went to try and crack it again. Nothing. Just continuously turning over, doesn't try to start, doesn't pop, nada. Just spinny engine.

We are into the grass cutting season so I hope you found your problem and now have a nice cut lawn.
I have read where these mowers do give 'cranking' problems but sometimes when you've tried everything all you may need is can of starter fluid to spray in the carburetor when trying to crank as all it may need is just a little help to make it turnover.

Sometimes it is a small thing that most people tend to overlook:
Some mowers have 2 gas filters and these have to be cleaned and/or replaced every season.

Oftentimes a "No Crank" situation is caused by a faulty solenoid, bad ignition switch, or a fault in one of the safety switches.
Theses are small things but can cause big trouble.
Also, be very sure you have a clean air filter every season as no mower will run properly with a dirty filter.

questions -

does it make any attempt to start or nothing happens when you try to crank it?
was it running before you replaced the belt?
What happened to cause you to have to replace the belt?

Did you follow instructions carefully when installing belt and you did not change or remove anything else?

Has it been running this season or is this your first cut?
Bad gas from last year? Should have all new gas beginning of season.
Checked filter? Will not run with a dirty filter.

Here is a video you might check out but you can discuss your problems with someone on this site also.

The questions that I asked above are the type of questions they will ask you so they can get to the original problem.

I have a Cub Cadet mower that will only start when it is jumped. It has a brand new battery, but as soon as you shut it off and try to restart it all it will do is click.

Sometimes after working on a mower it will have trouble getting gas through the system.
If you can put your mower on a trailer, I would stop by one of your local auto parts stores and see if they will try a spurt of engine starter spray to see if that will do the job. They will also check your air filter (very important) and your battery as well as your spark pug.

If you cannot take your mower anywhere you can buy a can of engine starter fluid and try it yourself. This can be tricky so I would recommend buying this from an auto parts store (instead of Walmart, etc.) so they can show you how to use it.
There are lots of videos online to show you how to use this but it's best to not get it on ignition lines (it may not damage lines but you'll have to wait for them to dry). You can also use WD40 (and other products) but regular engine starter spray is best.

I would also recommend buying a new air filter (even if yours looks good) as this is crucial to starting an engine after it has been sitting for a while.
Check your battery as it will need a full charge to start your engine.
Be sure you are using a new spark plug.
Also, if your mower has been 'resting' for a while and you left gas in the mower without an additive, you may have bad fuel and this may have to be removed or maybe add an additive but talk to someone at your auto parts store.

You should NEVER use starting fluid to start a diesel !

I've been having a problem with my PTO cutting out. It happens once I've been running it for about a half hour and when I put it in reverse. This is a new problem, I've had this mower for about 10 years. Last week when I was cutting, the mower sputtered and died. I assumed I was out of gas, but I wasn't.

In an effort to get it running again I have replaced the following parts: fuel pump, fuel filter, ignition coil and plug, PTO relay, and the ignition switch (it's been acting up as well). The engine cranks, but won't turn over. Also I now notice a knock while cranking that wasn't there before. Could the fuel pump be installed wrong?

Have you replaced the carburetor? The fuel line may also be clogged.

Seems it over heats,always check filters after use,for clogged debris,dirt,etc.Keeps the engine from breathing freely when it is clogged,check spark plugs.

My Cub Cadet LT46 won't start when the mower is cold. I have to crank it for several minutes to start it. Once I get it started, I usually don't have a problem getting it to restart.

I bought it used with just 60 hours on it. Help! How do I solve this problem?

If it is less than a year old it should still be under warranty. I would let the manufacturer fix it

If it is new, the store should be notified. You can void the warranty if you attempt to fix it yourself.

My small engine is a 640 Honda engine on my Club Cadet Zero Turn. It was working great then got caught in a thunder storm.

It will not turn over; it just clicks. Will it dry out or will it need to be serviced?

Your gas probably got contaminated. You will have to drain out the old gas and get new gas.
