I always check the fuel mileage on my truck and whatnot, but I've never really paid any attention to the fuel consumption of any of my tractors. Just curious how many hours you guys get out of a tank and anything you do to increase efficiency
It depends how many of those HP you are "drawing", e.g. plowing heavy will consume way more gallons per hour than light mowing.
There are various ag college studies and tractor test reports on diesel tractor efficiency, they seem to be about 80% the efficiency of trucks and marine diesels in "liters per minute per HP".
I think that is the unit of efficiency and it varies along the power curve.
60% of max power sticks in my memory as a "Good place" to run most diesels for minimum cost per unit of consumed power, i.e running cost efficiency.
As far as what I do to increase/improve "efficiency" ???
Well, just not doing what doesn't need to be done is the #1 strategy (-:
Then working efficiently as a general work method on what DOES NEED to be done.
e.g. "scatter out, gather in".
After that (a little bit controversial with some folk here) I run low power PTO jobs off the 1,000 RPM PTO at (about) 54% of PTO speed engine revs to get 540 RPM - - if it loads down I revert to the 540 output gear at full revs, but then it isn't a low power task (-:
