The "XP" stands for "X-Tra Power", and the difference between the two machines is that the 8780XP power bulges to 305 horsepower. I've also been told that the XP version has beefed-up hydraulics, in addition to other minor changes over the previous model; - it's the same basic machine though. I'll have one running alongside my Deere 9610 and Gleaner C-62 next week, in addition to a Gleaner R-62. Should be interesting!
