Is it time for a gasoline engine tractor?

I found it interesting when I read a few years ago, that a modern fuel injection system can put fuel to an engine like an old school, high performance 4 bbl carb never could.

I have not been following the evolutuion (up to Tier 4 final) off-road diesel engines. Do any still have a conventional injector pump and injectors? Then, if push came to shove, you should still be able to make it run, and just throw the rest of that stuff in the garbage where it belongs.

There was an interesting article in Green Magazine several months ago. A port injection system was retrofitted to a JD 4020 iirc. Power was up 10% and fuel consumption was down 20%.
That is just with a 1960's low compression engine. Direct Injection and high compression would move the gas HP/gallon/hour into the low-mid range of diesel efficiency territory. Gasoline efficiency per btu would be about par diesel. Part throttle load efficiency of the gasser would exceed diesel part load efficiency.
A single barrel carb on a log manifold just can't accurately distribute the ideal mixture to each cylinder.

Carburated gassers cars burning unleaded if they made it to 100,000 without at least a valve job and a set of rings . They were a wheezing oil burning clunker. Now a fuel injected gasser running unleaded doesn't even rate mentioning for going 300,000 with just filters, belts and two spark plug changes.
The 300,000 mile gasser makes more power per cu" than the old carburated gasser. Seem to hold together just fine without blowing up with the "added stress".

I guess I just must have the good ones...

My 1972 Plymouth Valiant has 220,000 miles original engine and towed my contractor trailer everyday.

The 1985 Chevrolet 305 V8 has 180,000 miles with original drive train... and it works very hard because from the first week I got it the tool boxes and rack plus supplies put me over GVW so much I had to add helper springs.

I drive a very steep hill several time a week for the last 20 years... it is about a mile up... I put it in first and just take my time... easier on the truck for sure.

Maybe changing my oil and filter every 2500 miles has something to do with it?

that was a light car...360 V8?

You just have good genes. Anyone who owns a Cat bulldozer has them.

Valiant has a 318 with auto and front disc brakes...

Used it all the time to pull a 1 yard concrete gondola back when you could do such things and welded up the trailer hitch myself...

The ready mix plant was never more than a couple of miles from the job on city streets...

I had to add extra spring leafs and air shocks to handle the load... also took out the back seat and built a platform for my tools plus the big trunk and a roof rack... it carried water heaters across the back on top of the trunk and 50' of 6' redwood fence, posts, rails and concrete...

We could run through 2 tanks a day running our M. Same usage with our D17 Allis Chalmers gassers.

I never had enough money to do much work with my gas tractors.

The person who told me about going through a tank before lunch said they'd fill both the main tank and the tiny starter tank with gasoline and when the main tank ran dry, that was the signal to switch to the starter tank and come home to eat and refuel.

We used to plow with D-17's and M's. The 17's would pull 3-16" bottom plows while the M's would pull 2-16's. They pulled like the dickens but they liked the fuel. All we had in the 60's was gassers. My dad sold a lot of D-17's. They were very popular in that era and you still see a lot of them doing lighter work around the farm. A 60 HP gas tractor likes fuel. AC rated them as a 50 HP tractor. They were rated at the PTO. They typically pulled 53 HP on the dyno. Most everything back then was underrated.

Who makes a diesel with variable valve timing, shuting down cylinder's and other shut stuff?

VW diesels shuts down all cylinders when you are not stepping on the accelerator. They have been doing this since 1998 in the USA. They refuse to bring over the start/stop technology they have had since the 80's.

The 318 was a very good motor.
