Would you buy a gas tractor

[Sawyer Rob]

Yes and I've never seen anything that had a gasoline "diesel". What would be the point of that?

Exactly how did it differ from the diesel version??

Lighter duty?? Different block??

Most are completely different air cooled motors. I've seen a few liquid cooled gasoline motors but they're still aluminum blocks.

THAT statement alone proves you have NOT ever looked at one... Just as I thought...

You should have properly educated yourself on the subject, BEFORE you declared I was wrong, in my last post about ----------> Kubota GAS motors in -----------------> Grasshoppers!

First choice: pre-DPF diesel
Second choice: A well built gas engine with enough extra displacement to equal the diesel at low RPMs
Last choice: a diesel with all sorts of exhaust complexity courtesy of the EPA

I'm a low hour user to fuel consumption isn't that big of a deal for me. In all cases the quieter the better. Both diesels and gas can be very quiet. Some of the new diesel trucks are quieter than their gas counterparts under load as per the ike gauntlet db tester.

So what's the point of turning a diesel into a gas. The weight is still there and most of the expense is. The emissions aren't as strict on gas, but they're looser in 25 hp diesels anyway.

Must of been a hat I never seen or worn, I use to watch racing back in the No. 43 days, dont recall a diesel motor. Opposite in how, hp is hp, 300 hp diesel is the same as 300 hp gas in my book, or maybe a lb of lead does weigh more than a lb of feathers.

Carb gas motors........... now that is old school and yes they've been known to be a pain in the donkey as like wise points and plugs, that has all been changed and greatly improve into today's gas motors, infact that was improved 40 years ago. Todays gas motors are ten times better than noisey smokey diesel without all the expensive high tech maintenance and the list goes on.................

Diesel race car a little farther back in time.

365*24=8760 hours in a year.
8760 hours times 16 years = 140,160 hours
140,160 hours minus the approximately 700 hours on my machine clock = 139,460 hours.

My machine has sat not running for 139,460 hours with 10% ethanol in it. I just replaced the fuel pump. The diaphragm had a hole in it. Can't be attributed to ethanol, and is most likely wear. Other than that, no fuel related prolems.

A pound of either still weighs the same; the difference is in how large a volume is taken up by the same weight of each. A pound of lead conducts heat very well, while a pound of feathers makes a great insulator.

Getting back to HP, horsepower is just torque multiplied by RPM.....but how you get there makes the difference. Which kind of horses you want to buy is based on whether you want them to run fast or pull hard.

The biggest problem with gas that I've seen has to do with using modern low quality gasoline in older engines. Those old carburetted motors were built with the expectation that fuel would always get better and cleaner.....but that isn't what happened. Instead, gasoline got more expensive and poorer quality.

Still, a lot of gasoline problems can be cured by nothing more sophisticated than good filtration and treating fuel stored in cans or carb bowls in a decent way. Also, fuel injection cures a lot of gasoline motor problems simply because a fuel injection pump has enough pressure to force the gasoline through more filtering steps. That helps more than it should.

I grew up on WD 45's, M and A Farmall's, and D17 Allis-Chalmers. All gassers. With gas less than 10 cents a gallon back then and farm subsides fuel economy was not a big issue. A D-17 Allis pulling 3-16" bottom plows will go through 2 tanks of fuel in an 8 hour day. That's around 35 gallons give or take. My Ford 4610 SU diesel burns about 1/2 that or so it seems. As many have said here big difference when you get above 50 or so HP on a gasser verses diesel.

Would I buy one. Not now. But if I needed a smaller tractor in the 20 to 30 HP range and it was offered at a substantial savings I would consider it. It will burn more fuel than a diesel.

Compression ratios of old 'gas' tractors are pretty low compared to modern cars, at the expense of o'all efficiency (bhp/L). Guys I retired with gripe about modern GM engines with 'pipsqueak' turbos vs big blocks. I doubt we'd see the same type/size engines as our JD 'B's, WDs and such come into tractor use.

Look for aluminum blocks and full frame chassis when you re-design tractors, or don't expect much crossover application from the car/truck side of the biz.

Diesels qualified at Indy and raced at LeMans. Racing nowadays seems to be about building brand image vs technical advancement. Technology will bring us a better life as soon as it's sorted out who will get rich of a patent. Until then it's just an avenue for capitalistic venture. I'd expect a surcharge on a 'gas' tractor to 'cover development costs' for engines to operate in a 'narrower' RPM range.

More emissions stuff? I'd expect to pay some kind of premium for the 'convenience of gas', one way or another.
