Thanks, from looking at other chain driver tillers that oil weight seems typical. Couldn't find any zerks, the left side has the chain drive, right side has a circular cover bolted over a bearing packed with grease. Not sure if it's designed well or poorly, I guess I'll find out. Sticker says made in Italy but only has Kioti labels, couldn't match it to anything and it's at least 15 years old so that would be tough.
