Oil & Fuel Grand L fuel consumption.

[Northland]

My B7800 used a gallon+/hr when I was snowblowing at top RPM last winter.

I was shocked at the increase over using the tractor for my firewood collection and landscaping chores.

I have always wondered why the B7800/3030 has a 4 cylinder engine while many of the other B's and L's have only 3 cylinders. Seems to me 3 cylinders would use 25% less fuel then 4 cylinders. Anyone know why?

That is true if the cylinders are the same size. But for a 1500 cc engine, a 4 cylinder engine will have smaller cylinders than a 3 cylinder engine. The total size of the cylinders is still 1500 cc's, so the fuel consumption should be about the same.

I noticed that if I run just under the rated PTO speed (wide open) I get better fuel per hour rate. My MX5000 sucked down 10 - 12 galons in around 6 hours tilling.

Well, I have to cut about 4 acres with a 6' rotary cutter. The grass is not high and will be easy cutting, so I have a choice of 2 tractors to use. Based on fuel economy, how do you guys think a Farmall H gas would compare to a Kubota L4610?

Fill them both to the top and cut 1/2 of the field with each. When you are done top them off once again and see how much fuel each used vs cost of diesel to gas. Great experiment with a definite answer. If you do it that way be sure to post your results. It will be interesting...

Any guesses on the winner???

That gas tractor is going to burn around twice as much fuel as that diesel tractor even though the diesel is almost double the hp. That isn't the case for all gas vs. diesel debates, but I have run a gasoline Farmall M and a Kubota L4200 and that was the case with mine. I could easily burn through the 20 gallon fuel tank in a day of mowing on the Farmall M and I can actually get a little more done with the Kubota with a 9 gallon tank. Not just because the Kubota gets more done in the same amount of time because it is more hp, I can actually mow for 12 hours or so on a tank of fuel with the Kubota. Discing I can only get about 8 hours of work out of a tank.

This kinda refreshed my memory, and I believe you are right. The good points about the Farmall: 1- It rides smoother, 2- The cutter is already attached to it. The bad is that it has a gas leak at the cut-off valve on the gas bowl. Kubota bad 1-rougher ride 2-boxblade currently attached. Good-
1-A/C 2-Radio.
Off road fuel Saturday before last was $3.5?, right in line with gas prices here.

My 1st bota, B7500 would run all day on a full tank. I cant even remember how big the tank was, 6 gallons perhaps? Those were the days, diesel was around a buck per gallon!

Those were the days, diesel was around a buck per gallon!

Ain't it the truth!!!!!!!!!!

So if I'm reading this thread right, guys with up to 10 hp more and a cab get the same fuel consumption as I do?

only if theyre working slower... Mighty Mouse burns a gallon an hour cutting the lawn.

I don't have any hard facts here but I would say my 5400 (60HP PTO Approx70HP engine ) doesn't use anymore than what has been quoted on 30 something HP tractors. I know I can run it all day splittin would at 1500RPM and the gauge hardly moves. Maybe I'm all washed up here but that size motor may just be large enough to loaf at alot of jobs therefore sipping fuel where as my other tractors would have been labored at the same task and really eatin it up. I've totally amazed at how miserly the 5400 is especially comparing my old gas tractors to it.

 

[jas67]

Both my B7100 and G1800 sip fuel.

I used only 1.8 Gal for about 5 hours of front end loader work, and 2 hours of post-hole digging.

As for my Gas vs. Diese comparison, my G1800 (16 HP Diesel) uses about 3/4 gal /hour mowing with a 48" deck, while my Simplicity Javelin ZTR, 20 HP B&S V-twinn, gas, uses about 1 1/2 gal/hour cutting with a 44" deck.

I now have close to 100 hrs on my 3540, my fuel consumption has dropped of a little. I can remember 1 big (15 acre) core aeration job last season where i was shocked at the consumption of my B3030. I was pulling a woods pl60, 1000 lbs with the weight tray full.

I filled my new duramax thursday and my dumptruck friday, (both diesels) $243.00 This has to stop! People wonder why the economy is heading into a bad place, its fuel costs!

$243??? that won't even fill the tank on my 4800. I'm spending that per week on fuel and then some.

I wonder why Kubota hasn't copied John Deere's "e-PTO"? My JD tractor puts out about 95 engine hp and can drink about 4 1/2 gallons per hour under a heavy load. If I'm just turning my 6' tiller, even at it's full depth, I can switch to the "e-PTO" setting and only use just over 2 gallons per hour. (my own observations by using the hour meter on my tractor and the fuel meter on my fuel tank when refilling) My guess is that Kubota and other manufacturers will soon have this option available. Since it makes a difference of about $9 per hour in fuel usage in my situation, I think quite a few guys would like to have the option available. If you're out working all day and this option can save you anywhere from $75 to $100 a day in fuel, I'd say it's a valuable option.

What JD do you have that uses 4+ gallons/hour?

Man, my 95HP CASE doesn't use more than 2-3 g/hr.

I've had 4 different Case backhoes over the years. I don't recall ever running any of them at heavy loads for extended periods of time. Even in heavy digging I only ran them at what is basically a high idle. Take the hoe off pull some heavy ground engaging equipment or put on a PTO and turn a 15' batwing rotary cutter to cut areas that haven't been touched in 6 or 8 years. There is no close comparison between a backhoe and a tractor in fuel consumption. Maybe with a similar hp dozer, like the 955 Cat I had, but not with a backhoe.

 

[Builder]

What JD tractor do you have?

 

[Dargo]

I make it a policy to not list the equipment I own here on TBN as opposed to some. It is not particularly something I wish to do and is viewed by many as being similar to guys wanting to compare their W2's or bragging about all of their possessions in a "keeping up with the Jones'" type of thing. However, the JD tractor I own that I'm referring to is shown here in a Nebraska test http://tractortestlab.unl.edu/Deere/Deere_5525.pdf When mine went out of warranty I had to injection pump turned up a bit, so I don't actually know how much more hp it puts out.

I had no idea a 5525 was 95 HP.
