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.

My D130 has a new battery and it will crank, but won't start. I checked the air filter and it isn't bad. When I pulled the spark plugs they were clean and wet with gas. I don't know what else to check.

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.

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.

I have a Poulan Pro riding lawn mower. I had it sitting for over a year and it work great before storage. I took it out of storage and it tried to fire-up, but it wouldn't. So, I cleaned the carburetor, changed the plug, and replaced the battery. Now it won't turn over at all. I get absolutely nothing when I turn the key. I checked the fuses and it has good gas in it. Any help would be appreciated. Thanks.

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!

Did you check the spark plugs? Also, is it in the right gear with the brake on? Mine won't start if its not in neutral with the brake set.

I bought a brand new Husqvarna riding mower. I used it for a month and then stored it in the storage for the winter. Now it won't start. So I used a jumper cable and it started fine, but once I turn it off it won't start unless I use the jumper cable again! Any idea what's wrong with it?

I have a 2003 Bolens riding mower, model #13AN683G163 which will not start. This began over a year ago, when I thought it was the battery. I replaced the battery and the mower started, but the battery would drain and have to be charged to be used again.

This year, it would not start even after charging. I replaced the solenoid, the spark plug, and the gas and air filters. The fuse under the seat is OK, and the gasoline is new. I have cleaned and lubricated what I believe is the starter, which is on the side of the engine, and often the mower does start.

Now, however, when I turn on the key, the flywheel turns a little, but the mower does not start. I have checked schematics online and even called Bolens, but I cannot find a starter, and Bolens has told me that there is no part called the starter. Any ideas?

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. Is it maybe the ignition module?

Check the fuse under the seat for the safety switch(that makes the mower cut off if you get off the seat) I think mine was a blue fuse.
