My experience has shown me that it is not uncommon for people to first replace the starter when there is any starting issues on a riding mower or zero turn. Now that you have replaced the starter, and that didn’t fix the issue, I would now recommend checking the battery. Is it fully charged and passes a load test? Are the battery terminals clean and tight? Have you checked your valve clearance? Check specs for details. Do you have a voltage drop? Is the new starter you installed actually the correct starter? If you cannot check these things, please take it to a shop to save yourself time, money, and frustration.

The battery is good and has been tested. The starter is the correct one. I have had to replace it twice since owning the mower. Could it be the solenoid?

Is it actually turning the engine over? Have you replace the solenoid at any time? The engine will not turn over on it's own. It has to have an outside source. That source will have to come from the mower it's self. Yes it could be the solenoid.

well a new solenoid and the mower started right up. when i throttled up the mower, the mounts where the starter is bolted on broke completely off.

New starter and solenoid replaced, and it started like a new one. However, at full throttle the starter mounts sheared completely from the engine.

What causes the bolts to shear? Did you figure it out?

No I didn't figure it out. The engine ran fine till I gave it full throttle. I gave full throttle to cut the blades on to mow.

Thanks. Very strange I hope someone can help figure that out. Just doesn't make sense to me.

Doesn't make sense to me either. Since the mounts were part of the engine and the part that sheared off was cast aluminum, I don't think there is much hope of fixing it

Oh no that is not good.
Expensive.

You can a good welder fix it if you still had the broken parts but may not solve the problem if you can't find what caused it. I think a new engine is around 4k! That's probably about half the price of a new mower!

Yes sir it is. I just bought a new mower. The old mower was commercial grade but it was a 2008 model. So I just thought it may be time for new one

Sorry about that. Did you buy the same brand? Did they at least give you a good trade?

I didn't trade. But I did get a great deal and the new one has a bigger engine. I would like to get the old one fixed. If i can get it fixed then I will give to someone who really needs one.

Should be able to get a new engine for around $2300.00 even for a FX series engine. What kind of starter did you put on it OEM or after market. If you would always post the Engine model and spec. no and model and serial no of the mower it would make thing a lot easier to access the information you need.
