I dont have an answer at all for you. But if your terrain will destroy a top of the line CUT and continue to do so in 600 hours, I would do something different. Like plant wild flowers/grass or landscape the terraces and just mow the flat parts. Because anything that will tear up a tractor that fast.. I wouldnt mow.
A picture might help.
As far as new CUTS if you are concerned about the MMM connection method, then dont opt for the autoconect. Go with traditional technology. You dont have to buy the autoconnect on the new 1 series.
Whatever you do, you might consider putting a temp guage on the hydro and maybe some additional cooling if required. Heat is the big killer in a lot of cases.
Wish I could help, but not sure I have much to offer.
