We have had our 800 head done and it sure makes a world of difference, not as good as a new 600 Deere flexhead but much much better then factory, our skid shoes now run flat instead of bulldozing at the front and wearing the skid shoes out on the front in one season. Agco knows about this modification but won't do anything about it, i guess they need a few more guys to complain about it to them, so anybody that has a new flex head tell Agco. It sure would be nice if Agco did this at the factory so it wouldn't be necessary to be done after. Come on Agco wake up and get off your hands, get going on this necessary fix NOW.
