Bringing an old thread back from the dead here for folks looking at used older X324's:
I have a 2010 now with about 600 hours. It was stored in a garage for the first few years, then it sat outside under my lean-to for the shop for about 7'ish years, then back inside the shop after every use.
- I had to replace the deck (at $1100 in 2014) due to hitting a stump close to the ground and it threw me off the tractor! It was a hard hit and deck was twisted, not just bent. But now I have spare parts!
- The hood is plastic and it gets brittle and will split, crack, and otherwise fall apart with UV, heat cycles, etc. Mine cracked into several pieces. A new hood was about $500!
- The gauge wheels and the brackets that they ride on will wear out quickly. The brackets are expensive.
- The ECU needed replacing at about 400 hours (it would just STOP after running for about 15 minutes and wouldn't restart unless I let it sit for a few minutes, then doing the same thing again0.
- Annual oil/filter, fuel filter, air filters, and spark plugs whether it needed it or not.
- I added the JD "anti-blowout kit" to the deck (basically two flat pieces of steel that bolt to the underside of the front of the deck) and it made a world of difference not blowing up clippings and dust from the front into your face. 100% recommend getting this!
- I had one transmission oil seal start leaking pretty badly last year. It was a few hour job and about a $10 seal.
- It's now 13 years old. Leaks nothing, burns nothing at 600 hours. I use it in the woods too, not just mowing grass, so it probably gets a lot harder use than most would do.
- Lots of grease fittings - especially keep the rear u-joints greased. They get a lot of dirt and dust that get trapped on the top of the transmission. I always blow everything off before putting it away.
- I added a fuel petcock/shutoff to the fuel line so I run the fuel completely out of the carb before storing it. I've had no carb issues or anything with it.
I plan on replacing the seat pretty soon as it's getting pretty beat up. On slight occasion (I'm still looking into it), when I get below 1/2 tank it will start acting like it is being starved of fuel. I'm suspecting a vacuum issue or a fuel pump. It is a mechanical fuel pump. The OEM is a Mikuni, but most briggs and stratton and other mechanical pumps will work on these.
