    Hey, I have a question ;

    Does anyone on here put K&N Air Filters on thier mowers? You acctually can get them for lawn mowers. If so, do they really make a mower more powerful?
    Is there something out there that I can get to turbo charge my lawn mower?

    I have a Snapper 38in/18hp Zero turn Top speed 6mph. Top mowing speed 4mph

    You want more horsepower be cuase your bogging or you want more ground speed? If its ground speed you have to change the hydros first....

    I would never put a K&N on anything I own. You do know why installing a K&N gives the engine more power, right? It lets more air through. More air = more dirt. Not good in this kind of environment.

    If you want more speed, get a better mower. If you want more power, get a bigger engine. If you wanna run K&N on anything you own you are nuts. If you look at the gains on large engines from K&N then a 300hp engine might gain 5 hp ... that means your 18hp might gain ... .2hp if any.

    What about adding some different exhaust? I always wondered what that would do.

    ha ha ha ha:dizzy: :laugh: :dizzy: :laugh: :dizzy: :laugh: but seriously ha ha sorry cannot stop a blower on meth oh yea !! just have to watch those cylinder head bolts. Add a free flowing K/N filter plus all the dirt it brings with it. CUBIC inches rule, go buy a bigger engine. Best solution would be to spend all your apparent xtra budget on good maintenance. tomo

    A few things off the top of my head to consider

    Bigger engine (18 horse for a 38 inch deck should be ok)
    Sharp blades
    Check for bad spindles
    Blade drive belt dragging

    You could do a bit of pulley swapping - IE. slowing the blades down a bit will increase the apparent torque/horsepower.
    If its only mild bogging adding a flywheel type weight to the blades/spindles might help you get thru it (maybe)

    Check out the hydro drive, a hang up can rob you of engine power.

    also look at your mowing habits as well.
