You can call me biased if you want since I work for an AGCO dealer but I always thought MF tractors from 8600 series on only had value in the transmission and sometimes engine.  In the few 8700s series we've delivered I really think AGCO got a lot right with that machine.  I just wish they would have gotten their poop in a group sooner because now they are off to re-design it again with a protect-u cab and make it a 9s and make it in France instead of US again.  I expect you'll be please though with the 8700s you ordered.

Only drawback is there aren't enough power ports (round AMP connections for 12VDC) in the cab from factory but you can fix that simply.
