    It has been so dry here in Va. and trying to mulch leaves ends up like a dust storm. I was wondering if anyone has any air filter cleaning tips. I have soaked the precleaner in oil, but this seems to be harder to clean with all the dust gumming up in it. Im running a lazer with a 22hp Kohler. thanks

    blow the filter out with an air compresor. To clean the prefilter soak it in gas than put a little oil on it

    When I had a mower with pre-cleaners, I cleaned it with oil gas mixed, after blowing off the excess. The gas cleans it and the oil in it lubes it. Straight oil is too much oil and this trapped the dirt good. It still use this method for my 2 cylcle and small 4 cycle engines. I now have 2 Choppers that both have the Donaldson Turbo air cleaners which I feel it the ultimate in air cleaning. The turbo spins and keep big chunks from getting in there and the dust is trapped in a cup. What gets by there is trapped by an expensive dry filter. This is what's on the old Chopper with 3,192 hours on it and the original 22 HP Kohler motor. It seems to work great. :)

    I went to a seminar last winter at a dealer there was a briggs and a kohler rep and they gave tips on maintenance they handed out some cool fact sheets and maintenance sheets Ill try to dig up and post here what they said about the air filters is dont use after market parts because thestandards they must pass are very low and about maintenance they said to clean the pre-filter w a detergent and the filter to lightly tap it dont bash it because the seals may dent...but they said not to blow on it any harder than you can by yourself because the micro filter holes will tear and open up and wont filter the smaller stuff even though the tears may not be visible to the eye

    Here's what i did .... on my walker it has a Donaldson air filter. on the intake tube i removed the turbo cab and installed a K&N off road air filter its a one peice unit with the mounting made into the rubber base this one fits 1.75-2.00 openings. it cost me $48.00 with shipping,its washable flows a lot of air and easy to clean.i have one on my 67 chevy and have sold a lot of them in my time.this is my prefilter-the Donaldson never get dirty it's been 4 months i have have yet to clean it after all you can only blow out a paper filter so many times, yea i wash it about every two days but saves some money and i know for sure nothing is getting into my engine that don't belong.

    oh and has far as this statment went "dont use after market parts because thestandards they must pass are very low " that may hold true on really cheap stuff but their playing that game on you ... i spent over 13 years in the automotive after market ......lets see prime line just for example.....sellsthier version of a briggs filter and guess what briggs makes it for them...
    as oil filters goes wix isa number one filter when it come to hd and durabilty lets see they make some kubota , cat,cummings air and oilfilters just to name a few and these names napa's premium line and carquest premium filters ....
    and wix branded stuff it's all a game and if its good enough for cummings and all the rest its good enough for me
    " lube-finder is also a good filter but they many concetrate on big earth equipt and over the road trucks only. oh champion plugs also make so stuff for ac plugs and visa versa...the list gose on. and on

    Here in Kansas it's like a dust bowl in August and Our lazers can mulch what ever you run over. Dust is a serious problem. I always blow off our machines after ever property. I run a Don. canister in my lazer liquid cooled but in my 25 hr Kohler I rinse the pre cleaner out with gas and blow it out then spray a fine mist of marvel mystery oil on the pre cleaner. I donn't soak it just a fine mist and then work it in with my fingers before putting it back on the air cleaner. Oh, and I wouldn't get any cheap air filters or oil filters. I run wix oil filters and catrol 10w-30.

    the walker mowers (diesels) have the worst location for an air filter,down low right in the dust.i usually change mine every month it's not too expensive since i found a place that sells original Kuboda air filters for $9.00 each.i thought of going with the K&N setup,but paper elements are proven to trap the dirt better than the gauze elements.i would like to make a foam wrap that i could oil that would fit over the stock paper element.surprised Kuboda didn't think of that.

    In the dealership that I work at we clean them with dish soap and water, the dish soap cut the old oil and cleans it throughly then we work a little bit of oil back into them and put them back in.
