    I'm opening the door for some 3rd degree flame...but here goes.

    Anyone "hot rod" thier mower? I've got a 2005 60" lazer/z with a 27hp Kohler air cooled. This spring it seems like i'm low on power, the grass is heavy and wet and all that, but it's bogging down. I am mulching and the blades are SHARP, changed every few lawns. Air filter has approx 10 hours on it, Motor is turning at normal speed and the belts seem to be good tension (not too tight, but not loose). It's probably running normally...I probably just need to have a couple of beers and forget about it.

    Anyone ever "hot rod" this motor to get more out of it?

    PS - I wonder if the mule drive could be mated up to a Harley engine. Say 100hp/100tq....

    Mulching is the problem. That is why the mower is bogging down on you. You could fine tune the RPM's and I've even heard of people switching out pulley's to increase blade tip speed.

    I know this is probably a dumb question but I've got to ask. Are you keeping the deck underside clean? A clumped up deck can really kill some power. Those clippings need to go somewhere and wet grass can really mess that up.

    jet engine.
    but already, lawn mower engines are designed to be much tougher and higher reving than car engines. lawn mowers work in an environment that is very abusive. My mower has more torq and more features like cruise control and electronic fuel injection, than the family sedan. the point is, you shouldn't modify the engine past the manufacturer's specs.

    premium will actually hurt you in the power department. How much work are you willing to put into it. My partner and I have a little john deere lawn tractor that we are turning into a sled puller. Its getting a cat diesel same motor the use in the ferris. But we modified the motor. I think it will have 75hp and 200tq. But this one is just for fun, not work.
