hopefully someone can help. I picked up an older lawn tractor for a project I’m wanting to do. I need to be able to lookup parts for the engine but I can not find a full model and serial number on the mower or on the engine. It is a John Deere and the hood has the sticker on it that says LX279 and the engine cover shows that it is a 17 hp liquid cooled v twin k series. But I can not find any other numbers on the engine or mower. I have looked around the engine block, on the valve covers, under the seat, and all down the frame of the mower. I just need to find something to help me find part numbers for the engine.
