Only $7,000. Thats weird. Somebody on the NH board says maintainence costs average $14,000 for every 500-600 hrs. Anyways, glad to see the truth told. Just under $8,000 is pretty good. The qoute I got from the local Case dealer who rebuilds CIH combines is $8,000 to $12,000 for every 1,000 sep hours depending on how deep you go.
