Combines lack of power in 9790

Call agco get it dynoed, sounds like the cummins isnt putting out the horsepower is should be, Cummins will have to set it up

I work at a CAT dealership and spent the summer with the 670 Challenger combine cutting different kinds of grass seed. I noticed while cutting and trying to un-load on the go, there was not enough power to do both and you had to back out of the speed. So it is not just the Massey that is having problems. Jeff
