Kioti DK40SE /W FEL
Does anyone know the fuel effiency of a DK40SE w/ FEL. Mine does not have a HST. I read several post with different answers - (1-3 Gal per hour) depending on the useage of tractor. Because of this the difference, I would like to break it down in section. If you have a DK45 or similar model or HST, please feel free to write your input.

1. Fuel per hour - no PTO
2. Fuel per hour - Bush hogging grass
3. Fuel per hour - heavy use with high RPM
4. Fuel effiency difference between HST and not having one

Also, how does Kioti's models compare to other models on the market with fuel consumption? I noticed it is a heavier tractor than most newer brands with similar HP.

Why???

And as all of us Kioti owners know the Kioti manuals are the gospel with no typo's or misinformation in them:laughing:

When its low I fill it. ;)

I find 5 gallons is a good weekend:thumbsup:
Now that I'm box blading alot I think I'm using almost a gallon an hour. Even heavy digging with the FEL doesn't seem to use much fuel. Problem is that the hour meter doesn't have tenths and topping off the tank is pain in the butt when the hour meter changes so I don't keep track.
I just tell myself its way less than hiring someone per hour!
Actually I had a look a the chart and averaging 20hp for an hour is sort of near a gallon per hour. So I guess if you are brushhogging using full pto hp, a DK50 could use 2 gallons an hour.

I recently took possession of a DK40SE shuttle and have been very happy with how little fuel it uses. I got 17 hours out of my first tank, and probably could have squeaked at least another hour out of it. That was a mix of loader work and log skidding with a pto winch. I am conscientious to run it no harder than necessary to get the job done.

I suspect heavy PTO use would burn more fuel, but I'm still impressed.

Seriously, Diesel fuel consumption depends heavily on how much power the engine is producing. They generally idle (warm) sipping almost nothing. It takes very little shaft HP just to move the tractor unless going uphill or moving earth. Running a rotary cutter or finish mower at 2500 rpm will use a fairly constant amount of power just to stir the air. I estimate about 2 gal/hr for my DK45S turning a 72 in fine-cut mower at 2500 rpm on the tach.

Compared to the Kubota L3700 I had I dont notice any difference in fuel consumption across various tasks. I will say it uses a little more when it is sitting and running the chipper over sitting and running a log splitter.

Mine is a DK40se HST

When I bought my tractor last week, my neighbor two days later bought an older 2040 JD. His tractor weighs about the same as mine even though his does not have a FEL. I was curious if the newer tractors are more efficient since a gallon of diesel these days is not cheap. Searching this topic in this forum came up with mix results. Some folks say their DK40/DK45/DK50 are pretty fuel efficient and others complain it being a diesel guzzler. I'm sure for some, it is how hard they work it. I guess I'm also curious if the Kioti is comparable to other models in fuel consumption.

Thanks everyone for you input.

I almost hate to post my unscientific results for my Dk35se hydro. (yes I know different engine than DK40se), but I will, and you can take them for what they are worth. When delivered the tractor had 4 hours, It now has 23. So 19 hours used, almost all at low RPM's setting stones on a wall, diging up rocks, hauling mulch around the yard..Just a little mowing for 1/2 an hour. (even then not at full 540 speed) I had about 1/2 of a gallon or less in the fuel can, and I dumped that in when I got the tractor. I then got another exactly 5 gallons and dumped that in. The guage is exactly where it was again as when it was delivered. So you can do the math, but lets say the gauge is off a little, still in the neighborhood of .3 gallons per hour. I know that does not seem like much, but it has been mostly puttering around, and not mowing a big wad of grass at 540 speed. In my experience that eats up fuel quick, and most any loader work is pretty easy on fuel. (especially toting around mulch:))
Ok I lied. I do remember putting the second 5 gallons now. so something less than .6 gallons per hour. Sorry

I am averaging about a gallon a hour depending on what I am doing. Loader work, backfilling and digging uses the most so far. Well see when the snowblower gets used, I'd bet almost 2 a hour. This thing sips fuel compared to the D3, I could use 30 gallons a day easy. CJ

I would think that air temp, elevation, etc. would have some impact on fuel consumption too??

But then again, w/out metering equipment, all our observations are purely subjective......just say'n.:confused:

If you look at the charts provided earlier, you'll see that you burn about 190 grams/hour/HP. So that's about 0.43 lb/hr/hp and a gallon of diesel is about 7 lb so this is about 0.06 gal/hr/HP. So if you are making 10 HP, you should burn 0.6 gal/hr. Don't forget about the hydraulic pumps and other parasitic loads (fan, oil pump, etc.) that consume power too.

Everything else is a second-order effect. The main driver is how much HP are you producing. HP can be all over the place except when you do something steady, like mowing. So 1-2 gal/hr is certainly in the ballpark for 15-30 HP total load on the engine.
