One of these days I may take you up on it. In the meantime I will practice on my 31 year old Wheel Horse garden tractor/lawn mower. Neighbors laugh at me in the spring when it takes me 20 minutes to mow the yard. When it hits 100f, they don't laugh as much. I always figured they were laughing at me, but MAYBE they are laughing at my mower. Those bastards!
