What Is The Difference Between the Boomer 3040 And theBoomer 3050?

[Utopia Texas]

I've had my NH Boomer 3050 for 4 weeks now and love how it operates and works. Earlier today I was looking at the owners manual and started looking at the specs comparing the 3040 and the 3050 and besides a slight difference in HP the units are exactly the same. All physical sizes are exact and all engine interior components are exactly the same including bore and stroke so how do they rate one with slightly higher horse power. I have looked at each and every spec. and besides HP the units are duplicates of each other. Is this slight of hand by NH. Or am I missing something here?

Are you sure about Bore and Stroke?

Often two identical diesel engines can have different horsepower ratings by the setting of the injector pump.

Sorry, I made a typing error. It's the 3045 and the 3050 that have the same specs. but show a difference of 5 hp.

The difference is the injector pump adjustment and that the 3050 is rated at 2800 rpm while the 3045 is rated at 2600 rpm. So, the power curve is adjusted to the change in the injector pump. The difference used to be that the 50 hp model was turbo-charged, but it seems NH decided to save money and do it with rpm and the injector settings on the newer models.

You can see the same thing with Kubota models, same displacement, different HP.

Does anyone think it's good, bad or indifferent to select the high HP end of a given displacement engine? Seems like the middle HP of the range would be a longer life engine to me, don't know if that is total nonsense or not.

Dave, I wouldn't worry about engine life, but I would certainly think twice if New Holland wants to charge $2k more for tweak on the injector pump that gave me 5 more hp. I'm not sure what the difference in price is. It could be even more than $2k.

Buy the lower HP version and after the warranty, have the injector pump turned up if you need the additional HP if that is the only difference. Might cost $100 for a mechanic to do that. Many (most all) brands have a series of tractors that use the same frame, engine, etc to produce up to 15 or sometimes more HP than the lowest model in the series. Sometimes they add turbos and or intercoolers to boost it up but sometime all they need to do is tweak the fuel delivery system to get more RPM and more fuel to the same engine. Usually the larger HP tractors in the series will have larger tires to apply that HP to the ground, so you do get a little more tractor for the $1500-2000 difference. What I see with the CUT's is that they run out of traction before they run out of power for ground engaging work and the only reason to get the more HP is if you are using something that requires more PTO power. Most of the work folks do with the PTO isn't using the full power of the engine with a few exceptions like when bush hogging and hit a really tough patch. Then it is just as easy to slow down a bit rather than pay for the extra power all the time you are running the higher HP tractor that costs xxxx dollars more for initial purchase and likely burns a bit more fuel too.

Gary, you do have to be a little careful with these tractors that seem to be the same except for injector pump tuning and rpm ranges. In some instances, there are different internal components for the different models. My example is the TC models previously built. The TC35 had different internal components than the TC40/45 in the rear differential and the hydraulic components were not as robust even though they were the same class tractor. For example the 35's hydraulic pump's output flange had two bolts instead of four on the 40/45 hp models. The maximum pressure for the system was 2300 for the 35 and 2500 for the 40/45. Of course, the TC 35 also had a different engine. My guess is that the 3045 and 3050 have no differences internally, but I don't know that for sure and I'd be afraid to say the 3045 could be tweaked to match without a lot more research. If I had to place a bet, I'd bet they are the same, but I'd hate to advise somebody that they were without knowing for sure.

Though the initial post was some time ago, I thought I would provide some additional information concerning this subject. I suggest that you check the info in the California EPA document here: [URL="http://www.arb.ca.gov/msprog/offroad/cert/eo/2013/ofci/u-r-026-0368.pdf[/URL] concerning IHI Shibaura engines. If you look at the second page, you will see various horsepower ratings, all for the same engine displacement of 2.216L. Here, you can see what makes at least the main difference in horsepower, is the amount of fuel injected.
