V2403 vs. v3307 Engine

[Kleeson]

I am considering a M5140 (V2403) or M6040 (V3307). About the only difference I can see between these two tractors are the engines and about $1500.
My question is..besides HP and CI, what's the pro's and con's of both engines. At the dealer, the V2403 sounds a little louder and maybe not quite as smooth. It seems to have that familiar "diesel ping". Also, on the dealer's lot, the 3307 seems to start faster at 35 degrees. I also, wonder how the longevity would compare between the two. I would appreciate any comments you have before I pull the trigger on one of these tractors.

Other than the fact that the V3307 is direct injection and 900cc bigger they will both run a long long time. The V3307 is at the low end of its hp range while the V2403 is approaching the top end of its hp range. If it was mine and the extra money would not break me I would go for the 6040.

If you are buying a "KEEPER" tractor that you intend to WORK, you will always be better off with the more HP engine.
I went from a 17hp, B7400 to a 32HP B3200. For what I do the B3200 is sure working a lot less. I don't notice much more fuel consumption.

I can give you an example of more HP with less fuel consumption.
A friend of mine has a feed and grain mill. He owned two old 2 stroke Detroit powered trucks that he hauled 80,000lbs most of the time. One was a 8V71, 318hp and the other was a 8V92, 440hp. He got 1.5mpg better with the 440hp, 8V92. I asked him why and he said that he could get up and over the hills faster in a higher gear meaning less high RPM for a shorter time.

I proved this myself with a diesel 1980's VW. I went from a 1.5ltr, 48hp engine to a 1.6ltr 52hp engine, same car same daily route. I picked up 3mpg with the 1.6 and it pulled the hills just a little bit better.

NO REGRETS.......Go for the V3307! My $0.02 worth

I would go for the 6040 also. It would do more without having to shift for power. More cc's/cu.in. is more torque at lower rpm. And as mentioned previously, an engine not working as hard even though larger burns less fuel.
