No Scotty. It is quite easy to see what Kubota is doing. They are inflating their purchase price to cover their financing scheme of 0%.
Let's not over think this. You're mixing two different ideas. It is quite fine if you don't believe what I'm stating. I am simply "relaying" from my experience and background knowledge.
The company I work for (Mahindra) does the same thing. I've seen this with my own eyes. A tractor that was say $22K one year, sustains a price increase of $3500 within 6 months or the next model year.
It's the same tractor with a different number variation such as 2816, 3016, 1526,1626, etc. These are all the same tractor just about with a smattering of cosmetic alterations and built by Mitsubishi.
What's different other than the model number: Next to nothing except 0% has been added to the sales scheme at different points on selected tractors. They have it covered
The only difference between Kubota and Mahindra is Kubota sustains their 0% for years while Mahindra seems to go on and off with the scheme.
