The local dealer here has really been pushing demos in the last year. I have a friend that demoed the 380, he said it did everything his JD9520 did. His only "complaint" if you will, is that the tractor runs so quiet you heard the scrapers rubbing on the discs. Seldom ever revs over 1400 rpm.
Have a customer that demoed the same tractor. They unhooked their JD8360r from a 13 shank Krause Dominator, and hooked up the 380. The Deere would pull it around 5mph, and the AGCO was around 3.5-4mph. The big difference was the wings had to be folded up behind the Deere to pull it, wings were down and the wheels all the way up behind the AGCO. I asked them if they would buy one, they said "no, they've all spent to much time in JD cab to sit in anything else now"
Both farms said they were surprised at the inability to induce a power hop, at all. Apparently the dual transmission set up performs very well at puting the HP where it needs to go.
Supposedly, AGCO is now working on a front tank mount bracket so you could just drop off the front weight and pick up the tanks. When I was asked how many gallons of capacity I would need, I told them 1,000 gal at around 12 #s p/gal. I was told that shouldn't be a problem, curious to see what they come up with.
