Simple question for my experienced friends...is the diesel option really worth the extra $4k? I saw big ugly stuff. I know there's lots of fellas here with a lot of experience, and hour meters to prove it. My guess the largest percentage of u guys are running gas...I also guess there's a large percentage running lt40's. You guys tell me what's the skinny? Thank you!!!

I never have ran a gasoline engine, so I guess I have no clear answer.  I am happy with my diesel, bout like the folks with their gas engines I suppose, they all make lumber,
only have a few chain saws I'm not suppose to use, but will at times, one dog Dolly, pretty good dog, just not sure what for yet,  working on getting the gardening back in order, and kinda thinking on maybe a small bbq bizz,  thinking about it,

I feel that the diesel engine option will pay for itself over time in ways other than the just $$$$ saved in fuel consumption.

The actual fuel consumption (gallons) is usually less than gas and the power curve is different too.

But I have the 25hp Kohler and I'm happy with it.
                    ^edit^
It keeps driving the blade and making lumber.

edit: I had 35 there instead of the (correct) 25.

Since 2003, Ive run a Kubota on my LT70. Prior to that, I had a 35hp gas Wisconsin on an LT40 for 6 years. The diesel is stingier and gives less grief than the gas wisconsin. But they both had/have more than enough power for the softwoods I mainly cut.Its a matter of choice/wallet... heh....

The dollar to dollar comparison is useless unless you know how much you are going to saw.  Used on a daily basis, the diesel will be a much more suitable power source.  If you only crank er up when you need a few boards, the gas option is by far the best.  On a circle mill, an old gas engine will drink all your profit, while a diesel will make you money.

I've never ran a diesel mill, but I suspect I'd like it a bit more than my gas. However, I get pretty decent production. If I were just starting out with no equipment, I'd probably put that 4k into a used forklift instead.

My mill has a 25HP Kohler and I'm satisfied with it.  That being said, I would prefer that it is diesel for the single fact that I store about 300 gallons of diesel on the premises for farm use and it stores well.  Gasoline does not store well.  As for the extra $4K, If I were using this mill as my sole means of providing for my family, I would opt for diesel.  I could NEVER justify it at the present time as I only saw for myself.

I've got the 29hp Kohler on my LT40.  I like it, mind you I am not a production cutter.  I suspect it would fair well if I upped my board count.  Diesel would have been my first choice, but for my circumstance, the added cost didn't justify it.

On another note, I have many hours on an electric bandmill.  Now there's power!

At $2.80 a gallon you should get your money back in fuel savings alone in 3000 hours plus saw faster in big wood. If your going to use it a lot get the diesel.   Steve

Thanks fellas...I was hoping everyone would say they run gas and its great, and that diesel isn't worth the price tag...no so much...thanks to everyone, especially the guys that reminded me that big gas engines are gas guzzlers to say the least...my own stupidity to not factor in BFPG in the equation, but its a big deal...I put 5 gallons of fuel in my current home made diesel mill and it runs FOREVER...

Had a lt-35 with the 25hp gas Kohler; it would drink about 7 gallons in a full day of sawing. The 51hp diesel perkapillar I have now will burn 5 gallons sawing for 8 hours straight, and put out a whole lot more lumber to boot. We just picked up a new SCAG mower for the farm with a 35hp Briggs vanguard engine on her. 8 hours of mowing burns.......i mean guzzles 11-12 gallons a day. If you have the dough get a diesel, if it really stretches the budget just roll with a gas, they'll still get the job done.

Both my mills had/have 28 HP fuel-injected Kohlers. Based on my experience with the first mill, I figured I couldn't use more power and didn't seen any advantage to the diesel. I was wrong.

Based on what I know now, the diesel is better than gas for production sawing (electric is best). If you hit a large knot or denser wood, you do not want the blade to slow down -- otherwise you'll get a ripple in the cut. Diesel is better than gas for delivering the extra torque to get through the tough wood, without slowing down too much.

Something else that may be a consideration is what tier IV emissions standards and ultra-low sulfur fuel is doing to the diesel engine industry. I assume sawmills also have to meet these standards, and in the trucks and tractors what they are doing now isn't pretty. Things have become way over complicated and over priced on these new motors, not to mention the extra maintenance. I find it interesting that many of the companies that run big fleets of trucks like Asplundh and the local power companies have been going back to gas trucks in recent years. Ford is reintroducing the gas engine option in their medium-duty trucks to meet this demand. The ultra-low sulfur diesel is another problem, from the lack of lubricity to much greater problems with gelling, but I guess we all have to deal with that now.

Now, does all that translate to sawmills, I don't know. But if they have to have DPF, DEF, computer controlled fuel management, etc on the new diesel mills that would be a real downfall to me, again, expensive and overcomplicated. Just something else to look at, fuel economy and torque aren't the only things to consider....

It all breaks down to projected use for power plants and sharpening equipment, hobby occasional running use gas engine and resharp. Sawing for hire, diesel and sharpening equipment will pay you back. If you can go electric it whoops them all. Frank C.

About 3 weeks ago, I sawed out a bunch of White Pine and White Cedar for a customer at his location.

I sawed just over 3,300 board feet of a mixed lot of 1" and 2" stuff, about half and half, and use 5ΒΌ gallons of gas.

I don't use the 87 octane, but opt for the 91 octane, no ethenol.  I think it's like running "hi-test" in your car, you get better mileage, same as my 25hp Kohler does.

Chuck - I learned the hard way it's much more profitable to pay the extra for the high test, ethanol free gas these days.  I didn't have a single thing that didn't start this spring after switching off the ethanol gas.  I'm very happy!  No down time, stress, frustration, etc. 
Last year EVERYTHING had to be torn down and cleaned to get rid of the white and green fuzz that likes to grow in our carburetors with the ethanol.  Bad stuff.

I agree with all the other comments.  For stationary production, electric is best.  For mobil production, diesel is best.  For hobby and lower end stuff, gasoline.  Of course there's exceptions to every rule.
For me, if it runs well and pulls the blade in a given situation, it's the perfect choice no matter what it is.

My fuzzy math says..if you will saw very frequently amd cutting alot of material...especially if you are going to saw 8 hrs a day in business. Smart money is on the diesel.  The doesel will pay for itself in longevity and fuel economy in relatively short time.

Hobby sawing? Biggest gas option you can afford.

Is this on a standard LT40 or a Super LT40? I always go diesel if I can, gas being such a pain these days. You just have to do the math. Initial investment, return on the investment in both actual dollars and reduced maintenance.

From what I have seen, you will recoup some of initial expense of diesel engine (if well cared for) when selling the mill later.  Higher resale value.

42HP Kubota diesel, LT40 super, only run out of 5 gal diesel on maybe a 10+hour day, carry an extra tank with me.  I suppose it might matter which diesel engine you get but I would not consider a gas engine on a new mill purchase sawing for business.   Another thing not mentioned is the reduced fire hazard and not having to be pouring gasoline during the day.  Also peace of mind to have the sawmill diesel containers with me when I'm pushing empty on my diesel truck.

Every thing I own that won't start has a gas engine. All my diesels fire right up. You just have to weigh the cost difference.
