Oil & Fuel Diesel Gal/Hr

[bpence]

I just saw this post pop back up on fuel consumption and it reminded me that I've been keeping track of diesel fuel purchases and consumption since mid-May. For my little B7100 HST I've run:

- since May 13 - 126 hrs.
- 100 gal. fuel -
- average usage - .769 gal. per hr.

Now, this is probably about 85% yard mowing with the 60" mid-mounted deck, 10-12% bush hogging, and the rest working with the back blade grading a couple of driveways. I usually mow & bush hog at about full throttle and do have some hills to contend with.

I don't really know if this is good fuel economy for a B7100 HST, but I'm satisfied with it. I also have an older JD 316 lawn/garden tractor that I still use for lawn mowing around the house and buildings and it doesn't burn gas near that efficiency level per hour (uses lots more).

JimBinMI,

My mighty NH TC40D just consumed 10 gallons in 8 hours = 1.25 gallons/Hour! Maybe I could use that coffee cup for the tractor that we've seen in some other posts./w3tcompact/icons/smile.gif Of course I was running at full RPM digging a driveway (very heavy load). I'm not complaining though, if I had to do that work by hand ... /w3tcompact/icons/crazy.gif I'm not even gonna think about it.
When not under that load and at a lower rpm the consumption rate is around .8 gallons/hour.

Any updates on the fuel economy question? Gordon now has over 10,000 hours. Is the fuel usage still about the same?

Also, for Rogue and TresCrows. How are your BX's stacking up against the 7100 and 7500 series? You guys figured out how much diesel you're burning yet?

I never noticed this thread before. I haven't been keeping real strict usage logs, but I know I haven't used 15 gallons of diesel yet, and I have 38 hours on my B7500. I'm not sure if my hour meter is factored by the tachometer, but since they are co-located, I suspect that it is. I have about 4 gallons left in the tank, so I "guess" I've actually used 11 gallons over a 38 hour period. Is this possible?!? /w3tcompact/icons/shocked.gif

I can't believe that I'm using less than 1/2 a gallon per hour!

Glue Guy,

It appears that your usage is in line with the past posts. This is really economical. I don't think my little 4 cylinder car could IDLE for an hour and use less than a gallon of fuel. There seems to be some correlation between size of the engine and diesel usage, but not as much as I would expect.

Hey Glueguy, Yes, its about right. I've had my B7300 since sept 00 and it came with full tank. I have put 18 gallons through it and only put on 40 hours.

My 14 HP briggs & stratten on my troy bilt tractor uses twice that. My Case DC (33HP) when used for log splitting was going through upwards of 3 gallons (gas) per hour. I quickly adapted my splitter to run off the Bota. What a difference.

Diesel Rules!
