Oil & Fuel B3030 fuel consumption

the rule with a diesel is more load = more fuel, once you get above about 3/4 rpm you fuel usage will also increase dramatically, bit hard to keep rpm down when driving a pto implement, because all of them usually should be run at 40rpm, which on most smaller tractors is near enough to WOT. 1 gal an hour is up there, but not what i would call extreme, just gettin towards that end of the scale.

sorry ment 540RPM, not 40.

On my B-7800, I use just about a tankful (I think it is 7 gallons or so) in 8 hours of mowing with a 60" MMM running at 2200 to 2300 rpms. Also I did notice when I was using the rotary cutter, it seemed to use more fuel than mowing with MMM. With my old B-7200 which was a gear tractor and around 17 engine HP I would mow for about 8 hours on 4.5 gallons of fuel with 60" MMM as a comparison.
