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.
