They used to be more efficent I am not sure were your 50% comes from and I doubt that would still be the case.
2) Diesel engine weight improves tractor capability.
A comparable gas engine is not much lighter and iron is easy to attach to a tractor.
3) Diesels run cooler performing field work.
Were did you come up with this? The cooling system is what cools.
4) Diesels have greater longevity where many express the desire to keep a tractor for twenty-five years.
Amazing I wonder how all those old gas engine tractors managed to run for many thousand of hours,
and many are running and working today. I would hate to try and count how many Farmall H and M's are still working, much less 400's, 460's, 560's, 656's.
Many of those have in excess of 10,000 hours on them.
5) Diesels provide high torque at low engine RPMs
Gasoline engines can have the same torque curve as a diesel, just check out the max torque and rpm of a Farmall 400.
6) Dealers have no interest in having service work complicated by gas engines.
I believe you are guessing at this. I was in service for years and never heard any similar sentiment by a dealer or mechanic.
The first 5 are comments in blue are from LouNY - I'm afraid I agree with LouNY on all those points. I think that Jeff was just trying to get a discussion going. He doesn't usually speculate that wildly. The last (#6) comment is mine.
One thing not mentioned is the cost of an engine. A low rpm gasser designed for torque and cool running is much less expensive to manufacture than a diesel engine. It weighs the same and has similar efficiency' it just doesn't have the requirement for super precision in machined parts. By now we all know that gas engines last just as long - and are easier to service. A gas engine sure would lower the initial cost of a tractor. And the emissions controls are far less expensive for gas than diesel. Frankly, I wish we had a choice of gas, diesel, propane, or electric for the power plant.
If we had a choice of fuels, I'd probably go for a gas-engined hybrid electric for my next tractor....just for the curiosity factor.

The subject is TRACTORS, not utility vehicles. Kubota's gas RTV 500 has been in the utility vehicle lineup as long as I have been posting on T-B-N.

You are dead wrong. The RTV400 was a gas powered rig, the RTV500 still is.

I got you beat by a few years...........................:laughing:
My B3350 regens around 35-40 hours, most of its work is mowing at 540 pto speed, 200 hours avg year, I personally would not want a gas powered 35 hp tractor, diesel around 60 ft lbs of torque at 2000 rpm, without the huge gears in the tranny and diff could gas really compete? I can run my tractor for awhile in my pole barn before the air gets funky, (i dont do it, but i have),i have no need for a diesel truck, but for me diesel and tractors gets it done.

I have a new Vermeer trencher/plow. It has a kubota gas engine. The sales guy claims the they could not get the engine to meet emissions regs and converted it to gas. We waited a year for them to work out the bugs, but the diesel never came. It beats the heck out of the old diesel Case plow it replaced.
