do you really have to run full throttle?

    I have noticed on my new viking that with the lack of rain and not much growth if i back it off a little from full it still mows just as good with less noise and probably better fuel economy, and maybe a little less wear and tear. But mainly because it kicks up less dust and is quieter. Anybody else do this? Does it cause any harm to the machine? On a side note so far I really like my viking, the ecs is the cats meow, and it is balanced so well. Much better than my old belt drive. So anybody else mow just off full throttle?

    later!! chris

    if its a zero turn and you dont run at full throttle the pumps arent cooled as efficiently as they should be...or so im told... i believe their cooling fan speed is usually determined by throttle. edit! *hydrostatic pumps

    I've been running at less than full throttle for years, sometimes as low as 3100 RPM. If I get on a lawn that needs full throttle then I do it. Usually I'm around 3500 RPM. It burns a whole lot less gas at 3500 RPM then it does at 3700 RPM.

    I have noticed that not mowing at full throttle cuts the weed stems better. you know the ones that stick up 6 inches above the grass.

    I say FULL THROTTLE! It's better for the hydros if you do so. Gear driven mowers, I couldn't tell you.

    I say a bit over where she will start to boog down.

    if the grass is thin why waste the full fuel mode when you do not have to.
