that will have a black frame and have a tier 3 perkins (Cat C6.6) engine. The transmission will be Dyna6. Dyna 6 is a 36 speed sequential semi powershift. It will do many varied and wonderfull things or just shift it yourself by bumping either the shuttle lever or the T bar on the arm rest.

I had a 2008 7480, which is a CVT with the same engine which I found to be a little lethargic. The later Sisu (the tractor would have a grey frame) is in a different league.

The machine your looking at could have lots and lots of toys, front suspension, cab suspension (which can give issues) electric SCV's, Datatronic 3, 50kph or it could have none of the above, 

The engine were rated at 150hp, not sure if the 6400 had a boost feature or not for transport and or PTO.

Some people have had transmission issues, some have had 12,000 trouble free hours, I suspect the former could break an anvil. You might get some niggly electrical issues.Other than that solid tractors.

These DO NOT have the separate hydraulic oil revervoirs like the CVT's do, it shared with the transmission like most other tractors.
