As someone planning on purchasing an acreage tractor in the next year or so, I'm hoping some of you experts will clue me in on the pro's and con's of diesel as compared to gasoline tractors. I'm comfortable with gas, know very little about diesel, so how about some pointers? My tractor will need to do more than mow, and I live in an area where the winters get cold, so the thought of diesel gelling because I neglected to put an additive in the fuel has always left me a little cold, but I know there's more to it than just that! Thanks!

I have a Fordson Major Diesel. I have run it in 15 degree weather (that is Farenheit) and never had a problem starting it up. It is very fuel efficient. I can use it all day long and use less than half a tank of fuel. This is partially because I can do most work while in idle. As for working on, it is the most simple engine I have ever seen. It is a lot easier to fix than my Oliver 66 gas. It is even easier to fix than my Craftsman lawn mower. I will admit it, I am a diesel fan. I love the sound of a well tuned diesel. So my opinion is, go with a diesel.

On a weekend i work with my fordson major on my dads brothers farm. It's not a diesel but cusion has a fordson major diesel we park them next to each other so if we need to we can jump start them. They were both restored and the diesel has all the troble in the world to start it. Gas no problem. plus petrol's are rare. more hp on a gas. easy to fix. I disagree gas are better all over.

I refuse to buy anything else that is not diesel. First thing we did years ago is bought a MF 135D to go along with the MF 135 gas model we already had. Since buying the diesel, the gasser rarely gets used. Much more lugging power at idle (ie...you don't have to run it wide open to get it to work), much less fuel cost, less fuel consumption, better dependability all around.

Then, we started over with the lawn mowers.....

First bought a JD LX188 that I loved, and talked my grandad into buying one like it. Then, stepped up to a JD 455D. IT IS A DREAM! I haven't done anything to this mower but change blades and oil in 8 years. Just get on it and drive. The LX, with the Kawasaki gas engine has to have a full service every year. Spark plugs, fuel filter, air cleaner, the works. Several times, we have managed to get some water in the gas tank, and had to take off and clean that out.

Just two experiences, but since then, we have also bought two more diesel lawnmowers, and my pickup is a Ford Powerstroke.

Seeing is believing! I even talked my dad into a new diesel pickup! He would have to leave home if he bought a Ford, so he bought a Chevy.

Just my $.02! I have diesel in the blood now! I even do a little tractor pulling with a turbo DIESEL!

Hi Lynn,

Go with diesel and you won't regret it.

Diesel at 140000btu has more energy available than gas 117000btu and is why it burns less fuel to do a better job.

Diesel runs at 50% of the rpm of a gasser and why the diesel last so much longer before overhaul.

Diesel has so much more low rpm torque available than a gasser and is why a gasser can't do the the same amount of work of a diesel.

Diesel fuel generally runs at 2/3 the cost of gasoline.

You usually don't run the tractor that much during the winter time. Cost of anti-gel additive is $8/300gal treatment "if" you need it.

Maintance cost is cheaper over the long run with a diesel. Fuel savings alone after two years will pay for most common repairs with money left over in your pocket.

Diesel is very simple to work on. You just need a couple of good books.

Have I said to buy a diesel yet? ohh ya I did mention it :) :) :)

The price of off road diesel in Michigan is about
a buck a gallon, compared to about $1.50 for
a gallon of gas, or green diesel. Why are we
all paying road taxes to mow or operate small gas engines, chain saws etc. This is B.S. To pay a third more for no reason, but to line pockets. I
would lean towards a diesel for dependability and
operating costs.

I have about 20 acres in north central Minnesota, I use a 35HP gas tractor 1964 vintage. I agree with the age of tractors that the older they get the more cost there is to repair them. I'm in the process of selling mine and will be upgrading to a diesel, but mine has never let me down in these cold winters yet. Good luck

Keep in mind that Diesels of bygone eras are a whole different critter than those built today,You really need an understanding of diesel engines if you buy one from the 50's or 60's and even the 70's. Also having a block heater does nothing to prevent fuel gelling. and fuel economy on a diesel is highly overrated especially as today diesel cost more per gallon than gasoline

I just paid 1.10 for off road diesel, I don't know what you pay for gas, but here it's 1.55

If you're looking at an older tractor, a carb rebuild, points and plugs are a lot cheaper than a rebuilt injection pump. Also, some older diesels have weird electrical systems. It's a different story if you're talking about a new (less than 30 years or so old) tractor - in that case go with the diesel.

Depends alot on what you are doing, and how big of tractor you are talking about. If you are doing light work with a smaller tractor, say under 40 or 50 horse, I would stay with a gas. If you are looking at heavier work, and larger than 40 or 50 horse, I would go with a diesel. If you get a diesel, you will want to get a fuel barrel to keep diesel fuel in. Most on farm fuel suppliers will deliver winter fuel. Just fill your barrel up with winter fuel in the fall, and fill it up with regular fuel in the spring. You can get a block heater that plugs into 110 if it happens to be a hard starter when it is cold. You can also use eather. Diesels are probably a little harder to work on if you are planning on doing the mechanical work yourself. Diesels are more fuel efficient. You better not get to far away from the gas barrel if you got a gas burner. Its a dime one way and a dime the other. I think it really boils down to what you are doing and how big of tractor more so than anything else. Always get a tractor a little bit bigger than what you need. But no sense in getting to carried away. Just my two cents worth, I would stay with gas unless you jump over the 40 to 50 horse range.

What additive??? I've never used a winter additive in any of my diesels since i bought my first one!! You use winter fuel in the winter, and use your diesel tractor like you always do!!! You couldn't give me a new gas tractor!!! NOT if i had to use it!! Robert

Lynn: The advantages of diesels in general are that they tend to last longer, are better on fuel, and have more low-end lugging power than a comparably sized gas engine. It's worth noting that you seldom if ever see a piece of modern heavy equipment with a gas engine--the modern diesels are just so much more economical to operate--both in terms of fuel consumption and maintenance. Gas engines have their place, particularly in smaller applications, but even there, diesels are making inroads. Excellent diesels are available down to around 20 hp by such makers as Kubota and Yanmar, and others (just mentioning two of the most common) though for the most part gas engines still are the norm below this. The vast majority of new equipment 50 hp and up is diesel. I wouldn't worry about cold starting too much--if you use proper fuel and have a well-maintained engine, most diesels will start just fine in the winter.

I agree TimV. I think Yanmar manufactures the small (<50hp) diesels for John Deere tractors. Technology has improved diesel engines tremendously in the last decade. A side note- diesel engines are prohibited from competing in the Indy 500 because of the power advantage.

Ray--that's an interesting point that I was not aware of. I could believe it, however. Diesels are making a real comeback in the auto market--they've done a lot to improve their efficiency as that's a big selling point in the heavy truck market (not to mention making the regulatory powers that be happy) and some of that same technology is cross-pollinating to the car market.
