Rubber tires = no contest in the resale........  Tracks =......ask machinery pete, or look on tractor house.

 Please explain to me how the deere hydraulics are "far superior" to a 7 or 800 series MT?    Cuz I'd like to know.  

 Repair cost must be an area thing.  3000 hrs on both mt's and still looking for a major repair cost.

 I haven't driven a rt, know nothing about em other than since they came out, the deere guys admit the previous machines were and are inferior to the cat machines in production the last 8 years.   When the time comes, if deere wants a shot here, it better be for the same money, then I'd consider it.  Still doubt the service can compete, but that'll be a gametime decision.

 8520T and 765 were the same money to boot when I bought back in 02, that was one decision I can honestly look back and say was the right one.

 Back to hydraulics........Me thinks your comparing machines built prior to MT's?
