We had one of those 7/6 mowers and used it for years. I sold it in 2001 because the deck needed repair and the blades were shot. Bought a Woods RD7200- good mower but not in the class with the old lilliston. Any way the other day I discovered a company in Florida is making mowers identical to the old lilliston. Mathis Equipment, Inc. claims they can provide parts for the old ones too, wish I had mine back now.
Thought I'd look thru the posts in Implement Alley and pass the info along.
