We have a neighbor that has 3 9120's chipped. He had a custom harvester with 8120's, one chipped.

The ground speed of the chipped 8120 compared to the unchipped 8120 was about .5 mph faster. The chipped 8120 did not have to slow down in the heavier parts of the field like the unchipped 8120. No real fuel savings noticed but productivity of the chipped unit resulted in about an extra 5-10 acres per day.

The speed and productivity of the chipped 8120 and 9120 was not that different. Both ran about the same ground speed but the 9120 used more fuel. Was also told that the chip may void warranty(meaning warranty is void) if it is determined that the chip had any contributing factor to any engine failure.

My question is: is the 9120 worth the extra money?
Also: Would you chip a new combine if it voids warranty?

We think the reason the chipped 8120 and 9120 were comparable in capacity is a result of the feeder house being run at the maximum it can handle. These were used in northeast Saskatchewan, Kamsack, really heavy tough thrashing conditions.

From what I've seen losses is the limiting factor for chipped 8120's so I question the need for a 9120 unless you don't mind throwing a little over. What were your neighbors finding for losses? Do they run small tube rotors? Were the fields pretty green after and was there a difference between the 8120 and 9120 for losses?

ST rotors, losses were acceptable and similar across all machines, heavy with some green immature spots. Again we felt the limiting factor was the feeder house. Also, would you chip your new combine if there is a chance of the warranty being void if there is a engine malfunction?
