    I hAVe a gravely pro turn 60" with the 27 hp kawi.. I really need to keep track of my fuel usage on my hour meter because that is when the mower is actually running, but i am only get about 7-8 hours of mowing done per tank. My other gravely with the 23hp easily gets double that, and i owned a 25 hp. kawi that was also very good on fuel.

    Is there a carb adjustment or something? its only got 170 hrs on it, and i think the fuel economy is getting worse cause i didnt notice it this much when i first got it.

    Maybe if there is someone that has this motor tell me how your fuel usage is??

    My 27hp kawi on my JD uses roughly 1.75 gallons per hour, maybe just a little less. Mine obviously is on a different brand, but it should be similar.

    I have a 27HP Kohler though and have the same problem. I'm just hoping it's because of all the rain and mowing high thick grass is the cause of the crappy fuel consumption. I have 400 hours on mine.

    wow, 1.75 gallons per hour, that almost sounds worse than me.

    Keep it coming guys, this is good stuff. I will Keep track tomarrow when im out and will let you guys know what i am getting on mine.

    I was doing some math in my head today when i was mowing.. With the 27 hp over the 23 hp. i am using 5-6 more gallons a week. at $4.00per gal. thats about $20.00 a week, at 26 weeks a season that is $520.00 a year extra in fuel. At five years, (the average I keep a my mowers) that is $2600.00 in fuel extra that it is going to cost me! whoa.

    My 23hp kawi on my 60" deck is borderline enough power, but its getting the job done fine right now. and it sips the fuel.

    I don't understand, I can go all day on 4.5 gallons.

    So let me get this straight...
    Ok, you're riding the HAWG!!!
    Omg omg !!!

    The Sooper Doooper Cadillac pooper of all Lawn mowers, you ain't sweating, sweat is for people who want to work and LOL,
    you are riding in style and comfort while all the rest of them puny lawn boys have to work for a living LOL and you know you
    shouldn't laugh but it slips out LOL and LOL some more.

    And you're wondering why it costs money to do that?
    Yeah, uh hmmm...

    Have you tried, you know, a lawn mower where you might have to work a little?
    Just a suggestion of course, and only if you're feeling up to it.

    If its not a DFI or a diesel and it has a carb they all suck gas don't care what anybody says. Know people who have them, own one myself and run a lot of them on all different brands and the carb jobs are outdated and cost you to run them. Why they still make them beats me. Its has to be the cost I guess.
