I'm a Kubota guy and that's just the way it is. No apologies here...
I suggest you look at total cost of ownership, including depreciation. Pick a prior model of several brands - Kubota, Kioti, LS, JD, NH tractor around the same size and hp as the one you are looking at. Find out new cost. Check out tractorhouse and craigslist listings. Assuming maintenance is the same and repairs are nil, find out which tractor retains the most value over 5 years, 10 years, 15 years.
I haven't done this exercise on paper, but my guess is that the Kubota owner comes out even with or better than the other guys due to higher resale value, despite the higher up-front costs.
I make a lot of purchases these days with concern over how it will affect my net worth. Depreciation is among the most important aspects of that decision.
Good luck and please report back if you do crunch actual numbers.
