    Has anyone used the heavy duty air filter conversion kit on their Kawie 23 or 25hp engines? They are the shaped like a cylinder. Do they do a better job ?
    Thanks, Joe

    is there one for the 15 hp. how much are they??? I dont even know if it would be worth it because the engine has 800 hrs and i dont know how good the first owner took care of it. PS... how long should a 15 hp kawisaki engine last if properly taken care of???

    The canister air cleaners do last a long long time. IMHO, they are worth the money.

    They actually filter better after they get the first coat of dust on them. You shouldn't clean them period just change them once a year. I think the manufacture will tell you not to clean them, they will keep filtering very good when you think they are dirty.

    I've had a lot of experience with this type of Donaldson filtering system on combines. The filter on a combine is virtually the same as the one on my Super Z except a whole lot bigger with a dust cup.

    I would service the air filter every 10 hrs. on a combine but you need to remember there is more dust going through that filter cutting soybeans for one week than would go through your mower in a life time of the engine. I would put a new filter in every year.

    When I would pull the filter out to service it there would be a half inch coating of soybean dust over the element. When I sold the last combine it had 3800 hrs. on it and I would add a quart of oil about every 25 hrs. and change it at 100 hrs. The engine held 17 quarts so you can see there was no oil consumption to even notice.

    Every machine that is run in dusty conditions at all should have the Donaldson cannister style filtering system on them.

    The heavy duty air cleaner (large one with inner & outer filter) is the best!!!

    I for one will never own another kawasaki with their stock air filtration.

    It's the worst intake air setup I have ever seen. The major problem is that it is designed to feed dirty air into the airbox intake. Not suited for commercial use at all.

    If you don't have the canister and you are like I was... cleaning the filter daily or more... it's totally worth $200 for the upgrade.

    Just make it a point not to buy another new mower that doesn't have the canister.
    It hurts the feelings a little to pay $200 for an air cleaner to upgrade it to work like it should.

    I can personally guarantee you are way ahead of the game with that system just remember not to try to clean it to often, I would recommend not cleaning it at all and changing it once a year.

    When you use air to clean one never blow outside in always blow inside out and I promise you cleaning one is not necessary. It is a mine game you think it is dirty to you when it is actually doing a better job of filtering because the pores are smaller from the coating of dust. I have done this for to many years with excellent service from large turbo charged diesel engines. No wrapped filter just the large single cannister filter on all my equipment. You know if it will handle the dusty conditions a combine runs in a mower is no problem at all.
