Oil & Fuel Diesel Gal/Hr

[W5FL]

PaulB,

No No No - Brushhogging is light work. However if you set the front about 1/2 inch higher than the rear the work increases significantly as it becomes a mulcher.

Find a 2000# disk or drop the scarfiers of the box blade to max depth and pull that all day and the temp gauge will rise a little. Actually pulling a tiller through ground that has NEVER been broken while set at maximum depth and in first gear, I figure does the same work per hour that I could do with a shovel in about 1 year! /w3tcompact/icons/smile.gif /w3tcompact/icons/smile.gif

Yes, Kubota designed some really efficient engines recently. They don't smoke, they start easily, and they burn the diesel very efficiently. They actually go twice as far on an oil change interval is the previous engines due to the engine design.

PaulB, I suppose the time on your hourmeter is based on engine revolutions instead of a clock. I believe (not sure) that my B7100 was a clock, but the B2710 is not. In other words, I think the B7100 simply registered the amount of "time" that the key was turned on, but I tried watching the hourmeter on the B2710 and when I was mowing for 3 days at PTO speed, it did register the same amount of time as my watch, but then I spent 4 eight hour days pulling a trailer around a pasture, varying the RPMs pretty frequently, but mostly 14-1500 or so, and the hourmeter only registered 17 hours in 32 hours of actual running time. And I went 2 eight hour days before refueling and wasn't really low on fuel even then.

Thats an important distinction. A hobbs meter will base time usage on RPM. This is how aircraft all do it, not on actual running time. The higher the RPM, the faster those hours accumulate. See, we can control time, not by going faster then the speed of light, but with our tractors, neat...

Wow Bird you have a Kubota time machine. Don't forget to use your seatbelt before using your time altering machine.
Guess they only put those on HST and not those slow glide-shift tractors like I have. /w3tcompact/icons/smile.gif

Which way does your hourmeter work, Gordon? Like Paddock, I was used to aircraft hourmeters which only register an hour on the meter in an actual hour of time if they are running cruising RPMs, and I thought that was the way all of them should work to more accurately determine engine wear.

Mine works the same was as yours Bird--Sorry for joking it won't happen again. /w3tcompact/icons/smile.gif

Bird & others,

Remembered from reading my operator's manual so I double checked. On my New Holland TC18 Hydro your "hour" meter is called a "Proof" Meter. Mine records an hour of time for every engine hour at 1833 rpm. Just thought I'd give you the world according to BLUE! /w3tcompact/icons/smile.gif

Jim & Gordon, ya'll really make me curious. 1833 RPM? I would assume that's well below PTO speed, even on a blue tractor/w3tcompact/icons/smile.gif. And was I wrong about the hourmeter on the B7100 simply being a clock? Someone else told me it was, and when you turned the key on, even without the engine running, you could hear an audible "click" every few seconds (I've forgotten just how long between clicks), and I soon learned the easiest way to preheat the glow plugs was to hold it for 4 clicks and it promptly started then (there was a visual indicator, but it was hard for me to see; impossible in sunlight). I just wonder how many different ways tractor hourmeters work. Another thing I wonder about is exactly what's different about the preheating or glow plugs to make the new ones so much faster. Maybe I'm just easily confused./w3tcompact/icons/laugh.gif

I'm curious about the clocks, too. I've never really paid much attention to how mine works, but I'm going to start. I know the big truck hour meters specifically stated that they were hours per 1000 rpm or something like that right on the gauge.

A number of years ago, VW came out with a faster glow plug system for the older diesel Rabbits and Jettas. For the really impatient folks, you could replace the glow plugs and relay to buy (literally) a few seconds. Interesting side effect was that a number of folks reported having to get a new battery after the switch. They were just higher wattage glow plugs, apparently. Which makes sense, because a certain amount of heat is needed to warm the engine up to the required temp. You can get it from a lower wattage heater over a longer period of time, or a higher wattage heater for a shorter period of time. There may be other ways to do it, but I don't know of any.

Mark, you mentioned waiting for the glow plug indicator light to go out before starting your engine. I'm curious; do you do that on the Kubota? I was accustomed to doing that with diesel cars and pickups, but I don't think the indicator light would ever go out on my B2710. The manual doesn't mention it ever going out, 10 seconds is all that's recommended for 5 degrees F, 2 to 3 seconds is all I've ever needed, but I've tried holding it for 20 seconds and the light never went out. Just wondering if the "L" models are different in that regard, like yours apparently is different by having a brake indicator light that I haven't had on the "B" models.
