I have prices on the Kubota but not the Kioti, I plan on getting a quote next week.
I dont have the kioti pricing anymore. But the difference in the 2601 and 2650 was $1000 MSRP. I went with the cab so i opted for the 2650 as its the only factory cab option, and factory AC and heat combined. Kioti was very good wasnt for the cab I may have went that way. With that said and done the 2650 was like 3k more than the 2510, but I got AC, and few other things. Also kind of came down to the fact I can find Kubota parts on amazon, kioti not so much, but kioti dealer did offere a pretty sweet deal, pick up and drop off for free while under warranty, and while under warranty if it broke they would do free rental of like machine while mine was getting fixed.
