I don't know much about the New Hollands as we are Gleaner people but didn't know if you noticed this write up about a farmer that tested a New Holland 9040 in corn. Sounds like you will be OK pushing those heads with a 9040. Here's what the farmer wrote about his experience. He did a great job giving all positives and negatives.
Ok here goes.
The combine has capacity coming out the who knows what. WOW. I've never harvested corn above 5mph before, let alone 8mph. At 8mph the engine load was only 75%. Unloading on the go at 6.6mph the engine load was 91%. The combine certainly has power.
The cab is extremely spacious. Like lay down and take a nap behind the seat spacious. The controls are extremely well laid out and very easy to figure out. This is a very employee operator friendly combine. The computer screen is very colorful and with a bit of training of the eyes very easy to figure out what you need to know. There are 6 pages of fully customizable information for you to browse while harvesting. The window into the grain tank gives you a good view of the grain up to a half hopper full. The control stick I found a bit awkward at first but after a few hours if felt right. I'm not too fussy about the resume button for the auto header height and used manual controls much of the time.
The unload auger is another highlight of the machine. Its unload height is exceptional and the new 2008 boot is much better at funneling the grain in a controlled manner. The grain saver trap door at the end of the auger does a good job holding back the grain if the auger is nearly empty. When the auger is full it does a TERRIBLE JOB.
The engine compartment features a wide open design that seems to work very well for New Holland. With no sheet metal to catch residue everything stayed very clean with no build up of any kind. The oils are all side by side for very easy morning maintenance and the fuel tank is right at the top of the ladder.
The rear access ladder in my opinion is much too steep and I can see climbing it carrying a jug of oil would be a challenge. I guess I'm too used to the ladder on the rear of the 2388.
The grain hopper is very large. 315bu and the filling auger does a very good job at centering the pile. Some combines don't so I consider this a very important feature. The auger and extensions fold down very quickly and easily, though I wish there were a few more foot stands in the hopper to make taking down the corner braces a bit safer. The hopper cleans out very well after unloading so switching crops will not take a great deal of cleanout.
The feeder house is very wide, as wide as the dual rotors so they claim there is no bottle neck as in a single rotor machine funneling the crop down. I don't buy it but that is what they claim. The stone trap is interesting. It is a pressure sensor that can be set from the cab. If it senses a stone, the entire floor of the feeder house opens and drops everything on the ground. The head and feeder chain also stop with a brake instantly as well. The reverser is a very slick unit. It can be run forward and backward and it has great power.
The lights at night are very bright and angled quite well in the field. However, on the road there is either something wrong with this combine or New Holland engineers never expected anyone to drive on on the road past dark. The lights seem to angle down and aim at the head and only the head. I couldn't see more than 15 ft in front of me. Good thing I only had a 6 row head or at the 20mph road speed I'm sure I would have smoked a few mail boxes.
Other than that it is a pretty standard combine, in cab adjustments for everything, drop down chopper, separate chaff spreader, you know the drill.
THE STEERING WHEEL!!! I know, it is a weird thing to complain about, but you are hanging onto it all the time so this has to be right. It is about 35% too big in diameter. It really made turning on the headland a chore. Also in typical New Holland style it is made of a rather coarse rubber which I find makes my hands sore by the end of the day. Same exact steering wheel as on our T7060's.
The boot spills grain when shut off full. This needs to be fixed.
Brakes are not powerful enough to lock up individual wheels. I found a mud hole and didn't have enough braking power to stay on the rows. Granted it has only R1 rubber up front, but still. This combine needs R2 up front for sure. Actually all combines do.
The ear saver on the corn head. It really inhibits your few of the gathering chains of 4 rows. I really don't like this. I understand it is saving ears but it is a menace.
Poly snouts break way to easy.
I guess that is all that annoyed me about the combine.
