    I have 3 lawn tractors with the Kohler 25HP engine. Does anyone have a conversion for he oil filter for a Fram, AC, Purolater or other auto filter? I'm tired of paying John Deere $14 for an oil filter when K-Mart next door sells them on sale for $2.49. If you have lots of mower usage, these oil changes really add up. The John Deere Part number is AM125424 if that helps.

    I use the Mobil 1 PL 10241 oil filter. It is shorter than the original filter but that is nothing to worry about. I have cut open the filters after using them and they are just like brand new. You can use the Mobil 1 number to cross reference to any other kind of filter but I would avoid the cheap Frams. They're not worth the cardboard box that the filter comes in.

    we use NAPA replacement filters on our 25hp kohler on our power trac. just take the old filter to NAPA, and they can cross reference it for you. I dont know the exact filter number, or i would tell you here. Also, ithink that the rotary corporation sells replacement filters
    for the 25hp kohler.

    I went to K-Mart and the Fram number is PH8172 and the AC Delco number is PF2210. I've heard good things and bad things about every brand of filters, but the FRAM was only $3.99 (It wasn't on sale) and will suit my purpose just fine.

    I agree with Jman. Use the original in all cases. The Kohler oil filter is designed for Kohler engines. You do have the choice of the short or tall filter depending of manufacture specs. Short filter pt#12-050-01 and tall, 52-050-02. Also if the unit is under warranty, and there is a failure in the pressure lubrication, an aftermarket filter could void warranty.:cool:
