When I decided to get a bigger tractor, I started out looking at used 100hp tractors that where from 2012 or older. Eventually I gave up on buying used when I realized that I really had no use for a tractor that big, and if I stayed under 75hp, I could get one that didn't require DEF.
I really liked the Kubota 7060, but the Dealer seemed to like it more then I did, and his price didn't seem reasonable compared to what other brands where charging. If I remember correctly, they wanted $62,000 for it, but I looked at several brands and I might have my numbers mixed up.
Once I looked at the Massey Ferguson 4707, I knew that's the tractor I wanted. Dealer wanted $55,000 for it with 7 years, 0% financing in Nov 2021. I said yes, and it was delivered in June of 2022. The price shot up after I ordered mine, and I got a 2022 instead of a 2021, which turned out to be a good thing because they came out with a better AC system in 2022.
I've never owned a Kubota 7060, so my opinion is just based on what I saw when I looked at it at the dealer, and also on a used tractor lot. I liked it a lot, but compared to the Massey, it seemed smaller, lighter, and not as industrial as the Massey. I feel that I got a lot more tractor for less money with the Massey 4707.
The 4707 is the same tractor as the 4708, 4709 and the 4710. They bigger ones have DEF, and REGEN. But what a lot of people do is wait until the Warrantee expires on their 4707 and then they "tune" them up to 100hp or even more. Same engine in all four models, just different smog systems, so it's a very easy tractor to get more power out of without spending the big dollars.
Not that I would do this because there might be some law against it, but I've met people who say they have done it and where impressed by the results.
