I'm looking between the Kubota L Series and Kioti CK series as well. A Kioti CKxx10 SE with all the bells and whistles is a little cheaper than a Kubota Lxx01 without any of those features. I don't think the spec differences are significant enough to equate to real world operation differences.
So, the Kioti has a better value proposition and slightly better specs. People on this forum seem to love their Kiotis.
The Kubota has a more established reputation for build quality and, in my area, about twice as many dealers. People on this forum seem to love their Kubotas.
Looking at the total package of the tractor with implements, Kubota has the edge on money paid out of pocket if financing - at least the from the quotes I have gotten for comparable models. A total package Kubota with Land Pride implements is a pretty appealing deal, and very convenient. A Kioti with a separately purchased package of EA implements is also appealing, but a bit of a hassle to get it all wrapped up together. I still have not decided. I will say that the Kubota dealer is the only one who has followed up with me after giving me a quote to see if I was still interested. It's a small thing, but it further reinforces that customer service aspect.
When comparing the Kioti SE model to the Kubota, I am interested. For some reason, the non SE Kioti does not seem appealing to me. I have to decide for myself what that means.
One other thing I noticed is that the Kioti has a flatter floor, but also a taller height to top of ROPS (99.2 inches compared to 91.7 inches). I kind of like how you site more "in" the tractor on the Kubota. Some like how you sit up higher in the Kioti. I think I would prefer the shorter ROPS for working around trees - something I have a lot of.
I still have not decided. At one time, I was dead set on the CK3510SE. I then started looking hard at the Deere 30XXe models for a while. After a couple months of thinking about my needs, wants and budget, I am now leaning more towards the
L2501. I vacillate one way to the next, so I think the choices are pretty comparable. I plan to buy something toward the middle-end of December.
