we traded a 7720 with 4500 plus on it for a 1997 9600 only 1180 engine hrs and 800 sep.hrs ! no 4x4 and single tires for just under 55,000! It has too been a better combine too run then the 7720 ! got a contour head 1999 yr for under $10,000 only 1000 acres on it also ! did we do good or did we get taken IJ
