How many gallons per hour do you use? - MyTractorForum.com - The Friendliest Tractor Forum and Best Place for Tractor Information

mbrun · 04-08-2011, 10:12 PM

Anybody out there keep track of how many hours of runtime per gallon of gas you get when using your lawn or garden tractor?

My previous tractor did not have an hour meter so I never really knew how much run time per gallon I was gettting. Now I have an hour meter I am going to keep track for a while.

Will be interesting to see if different tasks have noticably different results.

Well, using a single cylinder 14 hp kohler, I used just under a gallon mowing at full throttle for just over an hour. Now that Ive throttled back to half throttle, it takes me about an hour and a half, but now Im only using half a gallon.

Many riders will use just over 1 gallon per hour up to 1.50. Some diesel mowers will be as low as .90 gallons per hour.

Full throttle snowblowing with my 16 hp Onan twin cost me 1.25 gal/hr. Half to 2/3 throttle with the loader, that same engine used 3/4 gal./hr. It takes horsepower to run a snowblower, even just blowing air.

Rough fuel consumption for small engines is 0.4 - 0.6 lb/hr/hp, and I use 0.5 as a general calculator. Thats the brake specific fuel consumption (BSFC)and is dependent on the actual power generated by the engine. Backing up between passes while snow blowing doesn't require the engine to make max hp at full throttle. Gasoline weighs 6.0 lb/ gal.

A specific job will use a specific amount of fuel. Throttle position is not all that relevent except for how fast you want to do the job and if the engine can actually do the job at lower rpm and therefore lower horsepower.

My diesel does a little better. Half throttle loader work costs a little over a half gallon per hour. BSFC is around 0.35 - 0.45.

about 1 per hour on my X500 and my L130. my craftsman GT i never fill the tank all the way and i usually only run it about 1/3 throttle since it is just pulling a self powered tiller.

jim335 · 04-09-2011, 11:45 AM

My GX335, 20hp Kawa. mowing or blowing uses 1 gal. per hour.

gburnett · 04-09-2011, 04:20 PM

I'm amazed at how much gas some of the twin cylinders gassers can use over a gal/hr while some of my small diesel tractors burn very little.16HP Yanmar 1300d can't use much over a pint/hr. 31HP Yanmar 330 uses about 1/2 gal/hr.Even my 70HP Cockshutt/Oliver 1650D
only uses about 1 1/2 gal/hr while pulling a large round baler.

Kingwood990 · 04-09-2011, 04:33 PM

The John Deere X520 26hp Kawasaki V-twin uses about a gallon and a half per hour at full throttle. The MTD 990 16hp Brigg and Stratton single cylinder uses about two gallons per hour. Does not matter the throttle setting. Its a thirsty machine.

wizzo · 04-09-2011, 05:05 PM

Haven't tried to calculate it, but some tasks just take more fuel. If I had a bigger place, I'd surely go with a diesel X748...

How old is your X500? I've heard rumors on the Deere forum that after about 50-60 hrs the fuel consumption of the Kawa's drops off a bit. I guess we'll see...

PurplDodge · 04-09-2011, 05:12 PM

I burn 5 gallons of gas in 12 hours while mowing in my Cub Cadet.

evo803 · 04-09-2011, 05:52 PM

OP did not state a specific vehicle so

At wide open throttle ( 75 mph ) 60 gallons an hour , at a cruise(45mph) about 30 gallons per hour. Unfortunately I had to sell it because of my accident that disabled me.

In that case...10 gallons per minute:

davidg · 04-09-2011, 09:51 PM

mine's an '08 and has about 130 hours on it now. it did burn a little more initially, then after the first oil change it seemed to level on out.

PA318Guy · 04-09-2011, 10:03 PM

I would guess the 318 at WOT was using about 1.5 gallons. I was able to snowblow about three times per tank and was out 45 - 60 minutes per event.

Carl · 04-09-2011, 10:19 PM

My MTD 990 with 16 HP Briggs uses about 1 gallon per hour with disking and leveling ground.

My new Powerking with K361 uses a little more but haven't worked it enough to really tell.

My New Holland TC 24 DA uses about 1 gallon per hour working with the FEL. Next time am subsoiling will check cause that works it to the limit.
