    I read in another thread that one of the diesel mowers used app. 1 gal of fuel per hour. I have a new John Deere 757 and was wondering if anyone out there has any idea how much gas per hour these use app.?

    Fill it up and check the time. Each mower could and would be different. Different conditions and operators will make it change.

    A 757 at full power under load should approx take 1 gal. per hour. Thats your avg lawn not cuting a hay field.

    Not sure my Exmark LZHP with the 23 Kawasaki has averaged 1.624 gallons per hour since we got it new.

    We have used 78.1 gallons divided by 48.1 hours

    It should get better than that when it breaks in more. 48 hours isn't much yet. My mower with the same setup much better than that. When it was new it used more fuel though.

    Hey Hoss I sure hope it does better than that ! The dealer told me I could run 10 hours on both tanks and I think he was way off! Is it possible that the Ultra Vac is causing the crappy fuel economy ?

    Yes, in that case the vac is causing a lot more fuel usage. I get close to 5 meter hours per side tank when not running the vac. During leaf season it does go up with the vac.

    I asked my dealer about the 28 kohler efi and he told me with a 60" deck about 1.3 gph, .8 is a lot better than what he was saying!

    I wish the Kohler was liquid cooled/EFI

    I guess my 22hp Kohler is just a gas fiend.. It'll burn @ 1.5 gals an hr at "max" load, worst case scenario.. By worst case I mean cutting down 24" worth of St.Aug/weed growth in one pass.. A real workout.. I use that figure to estimate my fuel cost of operation.. when cutting normal growth, it does much better... :p .... And I STILL want a diesel...
