  1. This engine has pressure lubrication not splash even though there’s no oil filter which can purchased if desired

    • But in all available official documentation, the lubrication system is designated as “Splash lubrication system”

      • I think some of these that went on lower end model mowers were slash and the higher ones like my John Deere 14sb had pressure lube since it says it has it and I can buy a oil filter adapter

  2. I have oil leaking from a small hole on the bottom side of the crankcase. Before I tear it apart, can anyone tell me what may be causing this?
