Hi Tim, welcome to TBN!
This is just a gut feeling, but that price sounds reasonable to me. That's not a whole lot of hours, and those 50 series botas are very well built. Here are some numbers from a post from a while ago:
<font color="blue"> Kubota L2250DT w/FEL with about 1300 hours (1990 model). It was a one owner unit and is really pretty clean. Turf tires. They want $8950
Kubota L2350DT w/FEL with about 350 hours (late 90's model). Ag tires. Overall it is in really nice shape. It is definitely an economy model - spartan but would do the trick. Asking $8995

If you're not familiar with the "search" function , it's pretty amazing. There have been over 800,000 posts on this site, and a search on "2350" will give you quite a bit to look at.
Good luck, John
