Greetings Archwood,
I think your timing may be exceptional whether you know it or not.
In your sizing considerations . . You have more options than you might have had just 30 or 60 days ago. I'd be thinking about engine/system builders as a priority. To me . . that means kubota, yanmar, and iseki because these three EACH have decades of engine building AND they also construct the transmissions and primary components of their tractors. This sets them apart in my thinking . . especially when you're looking at a tractor driver who is a bit bigger than average in one or more dimensions. (Operating layout/sizing).
You've mentioned the kubota choices . . But what about the new Yanmar 221/324/424 choices? And while I chose a Massey (iseki) GC1715 , I understand Massey has now decided recently not to discontinue at least some of the 1500 series format (1523, 1526, and possibly the 1529 also) . . And then there's the new Massey 1700 series as well. With the 3 different groupings . . it puts Massey in a good position for scut thru cut needs.
My point is NONE of of the Yanmars or Masseys is old and dated product. The Yanmars came out in late 2013 and the Massey GC1700s and 1700s are later 2013 and newer and the 1500s first showed in late 2011.
Expect all three brands have full concept designs . . not just a good engine and a box of oem parts. Also they have great warranties and dealer networks and several design similarities.
AXELHUB, I stopped by MF dealer and they had GC's and 1726E's but no 1500's ... Even their website doesn't show them. I'm kindof in that weird size area right on the fringe of the SCUT's and CUT's. I think I'd really like MF if I could find something just slightly larger than the GC1715 but smaller than the 1726E (this is a full frame tractor with large dimensions I'd say like a large B or smaller L series in Kubota. The MF's seemed to be very strongly built and quality machines.
I'm not familiar with Yanmar's except when their engines were JD's main diesel powerplant, but I will look into them further. Thank you very much!!!
TYM has a couple models in this size range with Yanmar engines, but close dealer would be a problem.
If you are talking tier4 and want 20+ years, I would consider the R&D budget/expertice/time difference. Kubota has orders of magnitude greater resources to put into these new, complex systems.
I completely agree they are capable. But in this instance you have to look at investment just for the US market. (as these are American EPA regulations) So I think if you look at US revenue then Kubota dwarfs everyone but Deere. Kubota relies heavily on their US market share and sales. I can't imagine Mahindra does. (Although I'm sure they want to grow it.)I wouldn't exactly say orders of magnitude... 2014 revenue for Kubota and Mahindra are $14.7 B and $11.0 B respectively. Mahindra sold over 200,000 tractor units worldwide last year and are a more diversified operation, being in the truck and auto markets. I'd venture to say that there is little more complicated in the moving vehicle world than a modern automobile. So I'd say that they are equally capable of complex control systems as any other industrial firm.
