    I read here, on another thread.. someone said they learned that a wb uses a LOT less gas at 80%.

    So I actually tried this out and on one lawn and didn't see a difference in cut, mind you the grass isn't growing too much right now. But I have always cut at 100% throttle but have only had a wb for a few months.

    So is it common for the experienced pros to throttle down when it's easy to cut?

    Not common, but a really good idea provided that the quality of cut meets your customers expectations, and the rate of production meets yours.

    i dont worry about gas savings as i do wear and tear on both my kohlers with several thousand hrs on them. i throttle back to say 90%

    Whats the point of throttling down any? The faster the engine runs the better the cut, smoother running belts and hydros. Saving fuel is secondary, if the engine manufacturer thought running 90% or 80% would make their engines last longer then they would run them at 3300rpms not 3600...I run WFO myself.

    I actually throttle my engines up to idle around 3,850
    Once blades are engaged the RPM comes down to 3,600

    So far no bogging down ever. Even in bahia.
