I have been poking around with different search engines and finding it's not just us having problems. Here's one on it's 3rd engine
https://newagtalk.com/forums/thread-view.asp?tid=1131687&mid=10487266#M10487266 and there are also bad clutch and transmission issues. Looks like Kubota used to replace engines but seems the new ones are still problems. Wish we could get everyone with problems on this forum because the posts are spread out on forums that don't always show up in searches.
I'm also wondering if atomburst bought his new or it was one that someone dumped.
Next week I am headed down to the Kioti dealer to get prices on a 25 or 35 hp cab tractor that originally was going to be another Kubota. After going through this I just won't stay loyal to Kubota anymore. Figure Kioti warranty can't be any worse then Kubota and the savings would fix a lot if they are.
