Does it seem low all the time or just when harvesting. At our combine clinic this summer they showed us back behind your variable speed rotor belt, are a few grease zerks. That greases that sliding mechanism that keeps rotor speed going when engine rpm drops. If that gets stuck it will wear a groove in one spot and keep it from sliding corectly when the right torque is needed. That will slow your rotors down making it feel like you are boging it down. Just thinking outside the box.....of course try the obvious, fuel and air filters ect.

Have an 05 CR970 & it seems to be down on power. Local dealer (in AUS) doesn't have a clue. Is there any way that they can boost the power via laptop or a power chip or anything at all as it it very frustrating.

Thanks 2rotors but the problem is worse than that. From new(now 625 engine hrs) it has been down on power in heavy going or even when unloading on the run. Complained to dealer but they claim there is nothing they can do, can't even tell me that it is actually getting full power. Hoping to find a cure with a chip or card or black box? Any suggestions much appreciated, Bardo.

Hi Bardo,

Reference the power issues you are having, we can certainly help out. Your 970 can be increased in hp and torque quite alot. We would do this by reprogramming the management in the engine control unit. My email is on the site so send me a message and we can discuss it further. We are Melbourne based.

Regards JOHN

This age of CR had the max power curve calibrated too low when compared to the high idle RPM. I forget the exact numbers but the engine runs at like 22-2300 Rpm and max power is developed at around 18-1900 Rpm meaning that the machine "lugs" down all the time before it has full power. Afte the first season New Holland recalibrated the max power poart of the curve to much closer to operating Rpm and made the machine twice what it was before.

It just sound to me like this might have been missed on this machine. Any New Holland dealer should have access to this info on ASSIST.

Might be worth asking...

steinbauer has a box for the iveco 10L engine. That might help too.
