Hi Everyone,

This is just a note for everyone regarding my experience. I wish I had more to share...

I have a 2013 JD X360 that mainly gets used to cut my 1-acre lot on a slight hill. The hill is so slight that I can cut up and down or across with no issues. The only other thing I use it for is to pull my Agrifab leaf vac (I got this in 2024) in the fall. On Saturday, I was cutting the grass and something violent and tragic happened inside the engine. It came apart big time. It did not come through the side of the block but the engine was seized at that point. I do have a local small engine shop/lawn mower junk yard and he had an X320 with a 22hp engine (slightly more hours) so I was able to get it replaced with that one. A new one was $3500 so that was not an option. He has not taken the engine apart yet but said that he found the oil at a normal level and looked like it was ready to be changed. That makes sense as it would have been done in the next few weeks before winter storage. I pick it up tomorow so we shall see.

For some stats:
2013 X360 with the 22hp motor
545 hours
Oil and filter every year as I store it in the fall. I use the the JD LG265 service kit

If anyone has had a similar experience I would be interested in knowing more for interested than anything. It’s one of those things I could not do anything about. I had the mower serviced for the 1st 5 years by the local JD shop where it was purchased. I change the oil, air filter, plugs and fuel filter annually as they all come with the service kit. I only put about 40-50 hours on it each year. I did the transmission/steering filter service at ~200 and 400 hours as well (longer than recommended I know).
Hello L.,

545 hrs. and about 12 seasons of use. I think you discovered the "lifetime" limit of that particular engine. I see similar models around here that seldom survive over 350 hrs. It is mostly due to lots of sand and poor customer maintenance habits.

I recently had a fairly new Cub Cadet that did not make it 100 hours because nothing was maintained except refilling it with fuel. The crank was seized in the top crank journal of the engine block so bad it could not even be pressed out.
