I have been looking at the same range of tractors to augment a AC 6080. I like the TS it is a nice heavy tractor almost 5 ton with cab and mfd. I would have liked the wet clutch to be standard, but I would assume the pshift has it. You might also want to look at the AGCO White/Allis. I have an Allis dealer nearby so I looked at the 8775. With cab and mfd it goes about 5.5 ton, 95hp, wet clutch, 32spd pshift standard and I think 27 gallon hydraulics if you are thinking about a loader. I know it is a lot beefier than the old SLH AGCO's. On the used market I would still take one of the 8610 or 8630 SLH AGCO's. Probably more in my price range.
Good Luck
Jim
