Its because its a bigger engine to produce that same HP as the gas one. As I mentioned before, our gas IH2500b achieved very comparable results to the diesel they offered in the same tractor. But the diesel had to have about 25% higher displacement to achieve those numbers.

Don't know if mentioned, but the gasser isn't drive shaft driven to the mower deck, I don't believe and the BX is. I'm pretty sure the power transfer system to the mowers is drastically different between the two machines. Those small mowers that use a bunch of pulleys to run the deck lose most of their power in that system. Not saying that's the whole reason. The diesel still probably has more power. I just didn't see this pointed out.

I had an old gravely 10 HP tractor and that thing was unstoppable in the deepest of grasses. Why? Power delivery system. Direct motor drive to gear tranny. Shaft driven mower deck. No belts anywhere; all short/no shaft. Take that same 10 HP and put it behind a pulley system and it would be anemic. You have to be careful that you are comparing similar systems.

BTW, I think a gasser could be designed to be just as effective as diesel in a CUT/SCUT. Is there any advantage? Price? Reliability? whatever? I don't know. Maybe; maybe not. I think it would be a business loser though unless it would be significantly cheaper. And I doubt that would be the case.

The EPA mileage tests are an even plying field to obtain and apples to apples comparison of mileage. Who should be believed about a machines performance? Lab techs using calibrated equipment under known repeatable conditions ? Or what some Bubba on the Internet or down at the tavern says his vehicle is getting for mileage?.

So testing a car on a dyno equals "Lab techs using calibrated equipment under known repeatable conditions". I guess in a way you are right. Dyno will give the same numbers for the car every time. How that translates to "real world" conditions is beyond me.

You should probably just quit because with every post you make you just further prove you don't know what you're are talking about and your added bluster of calling us "bubba", using country folk talk babble like we're a bunch of bumpkins or speculating on our "masculine"ity isn't adding to your credibility one bit.

The EPA does NOT do real world testing to determine the MPG numbers on a MSRP sticker. They take data from the mfr's and do theoretical number crunching to come up with an ESTIMATE. You might want to pick up this thing called a dictionary to see what estimate means. If the EPA did do real world testing, then why did it take them years to determine just last November that Kia and Hyundai were publishing false MPG numbers and took them to court? Yea, EPA took action to look like they are "looking out for us" but the truth is it just shows how inept the agency is (like most govt programs that just suck the life out of us by continually growing and gaining more and more power).

Go to a car lot and actually read the sticker. The EPA puts all kinds of CYA language on the sticker saying the MPG numbers are an ESTIMATE and you are not likely to get those numbers. Again, the mfr's are the ones that have all the testing equipment and do the actual testing ... the EPA just verifies the data and does some black magic to see if the mfr numbers are sane. Again, if they did real world testing they would know right away when someone is pulling the wool over our eyes.

Hey, but don't take some "bubba"'s word for it. Read about it yourself:
The Truth About EPA City / Highway MPG Estimates - Feature - Car and Driver

"But it took the EPA two years to act after fielding hundreds of complaints from Hyundai customers that the mileage they were experiencing wasn't even coming close to the official EPA estimates posted on the vehicles when they were on the dealers' lots.

For many, the explanation of what happened was an eye-opening look at how the system works: The EPA establishes the tests that yield the fuel economy figures, but for the most part it doesn't conduct the tests itself. It doesn't have the budget, equipment or manpower to test the hundreds of individual models with unique engine and transmission combinations that automakers produce each year." Here's Why Real-World MPG Doesn't Match EPA Ratings

Again, there are these things called search engines like Google that will help straighten you out on all this stuff.

Some people swear allegiance and loyalty to various ideals, corporations, institutions, teams etc. "Diesel" is one of them, it must portray some manly masculine concept or something? Why some people still stand there and defend something that WAS best in the past but has now been superseded is a mystery.
It's not 1969,1972, 1989 or 2006 any more."

If you took the time to read the GDI info I laid out before you you would know that it is YOU that is being a fanboy for a technology that is facing more problems than today's modern diesel. And my tractor is a 2012 thank you. Just because Tier IV is the current thing doesn't make everything that came before it instantly crap.

And finally, I'll add in a personal story for free. When I was a young boy in Michigan, my dad had a few VW beetles he kept and always worked on because they did so well in the deep snow we used to get. I hated them. They stank, sounded funny, heaters didn't work, you had to have a roll of paper towels to wipe the inside of the windshield to see where you were going because the defrosters didn't work for crap. My family worked for Ford in Detroit. I get A plan pricing on Fords still to this day. I still have a F-150 but it isn't my daily driver. It took me a LONG time to warm up to the idea of ME driving a VW anything vs an American made car (my grandpa would probably roll over in his grave if he knew I had two German and one Japan car in my driveway). But I got tired of being taken for rides buying American cars. I'd buy one, it would have problems, I'd try to get dealer to fix them, they blow you off until warranty is out ... by the time you realize you have a piece of crap you can't sell it for anything because it depreciated so much. Started observing my peers in the same situation (military members driving crazy miles) as me and what they were commuting in and what their operating costs were. Discovered TDIClub and took in all the info I could educating myself. When I determined there really was something to this "TDI diesel" thing I bought a TDI. Was so impressed I bought another. They aren't perfect, all vehicles have flaws ... they are man made after all. But with some education and a little determination and the resources I've mentioned before, I've been able to keep both running over 10 years with minimal expense and even though you don't believe it have saved me money in fuel bills compared to what I was paying before when gassers were my daily driver. They get the same or better MPG's then when I first got them. My wife and kids run around in a 5 star crash safety rated TDI with 14 airbags. There are videos on YouTube of them being involved in high speed front end crashes where they are totally unrecogniseable and the occupants walked away. I know one person that was in two offset head on crashes with one and was unhurt both times when police, EMS etc. said they should be dead. After the first crash they were so impressed with the performance they bought another just like it (gasser mind you but the same car).

So I'm not loyal to any idea, corp. or institution. I know how to think for myself and research and pick what works.

I've said my piece and backed it up with facts and not babble. I'm done now. Let me know when you get your GDI tractor. I'll probably be dead and gone by then.

Nebraska test 849 Deere 4020 Diesel:

At engine rated speed (2,200rpm), 91hp and 6.4gal/hr fuel consumption.
At PTO speed (1000), 83.5hp and 5.6gal/hr fuel consumption.

Nebraska Test 850 Deere 4020 Gasser:

At engine rated speed (2,200rpm), 88hp and 8.3gal/hr fuel consumption.
At PTO rated speed (1000), 80hp and 7.2gal/hr fuel consumption.

Yep, I can readily see how the gasser would have been a smarter choice than the diesel. :confused2:

Wait, aren't you the one against mentioning 50 year old machines?????

Yeah that got me thinking of the ford Gas -diesel comparisons like the early Ford 2000 series with the 158 gas and diesel engine.

diesel pto hp 32.09hp gas 30.85 hp
draw bar hp diesel 28.10hp gas 26.49hp

Fuel consumption Gas 10.79 horsepower-hours per gallon


diesel 14.23 horsepower-hours per gallon


Major difference in fuel operating cost...

Well, with last weeks gas prices (from U.S. Gasoline and Diesel Retail Prices $2.068/Gal for Regular Gas and $2.831 for ULSD), it would cost the following per hour to run those tractors at PTO rpms and engine rated rpms:
Tractor
Engine RPMs
PTO RPMs
Diesel
$18.12
$15.85
Gas
$17.16
$14.89
As such, last week the gas tractor would be cheaper per hour to run than the Diesel one :D.

In the summer the picture will be different because we are in the winter season now and diesel costs more because it competes with other products around the same level on the distillation tower (home heating oil, kerosene etc.)

And if you pay attention to the GDI articles I posted, this is the calm before the storm for gasoline. GDI's can't meet emission standards and are killing us at 10x the level of diesel but nobody knows it. The specs got kicked down the road til 2017 or something like that but gasser will look an awful lot like diesels with DPF's to meet specs. and Ethanol doesn't help the situation at all.

Diesel fuel and engines have already been through this churn. Now it's the gassers turn!

Actually, per this article: Will GDI engines mean higher particulate emissions? Thanks to already-enacted Tier 3 standards, no | International Council on Clean Transportation Ethanol helps by adding more oxygen during the combustion process and using a different injector spray pattern could take care of this problem.

That's a little different than most articles I found that appear to be published a month or two after that. Who knows. Sounds like new emission standards are coming from everything I read. I guess we'll have to wait and see how it all shakes out. This news appears to be more tamped down than the diesel changes. I never heard of some of these before.


Update. As I was. The article you posted is newer than the ones I posted so it may be more accurate. I was thinking one was from end of 2014.
