Bought a used John Deere LA115 last year and now need to put it away for the winter. It was essentially "gone through" by a kid who rebuilds mowers and I took it to the next level and detailed it.... even buffed it out etc. It looks brand new.... Got the number off the oil filter and it was a 492932S OEM Briggs filter. I looked at Amazon and Ebay for a deal... found none, but also found a lot of cross references that would work including a Fram 8170.... but stumbled across a great deal on a company called "Russo" filters supposedly for commercial applications and they make a compatible filter for this mower and the reviews were all very good.... Anybody use Russo filters? And can anybody tell me the difference between a 492932 filter and mine that has the letter S at the end of it????
