I have a Husqvarna 2042LS riding mower and would like to change the oil filter but even on the Husky website it is difficult to find a part number, which I would hope I could cross reference to something I can find without going to a Husky dealer. I have the owners manual which just tells me when to change the filter but there is no part number given. I spent 30 minutes this morning searching and came up empty. Can anyone advise me how to find a filter for the mower? Thanks, Larry
