Less Hp, no CVT rotor/header drive, smaller cleaning area/grain tank. The 7120 is basically a New Holland combine w/ a AFX rotor. The 7088 is a new size in the good 'ol IH style combine. I think the 7088 is proof that the 88 series isn't going anywhere. I think there is still a lot of demand for the 88 design & class 7 is the most popular size right now so it makes sense. I'd like to see a sales comparison.
