Lawn Aerator Made With 130 Bolts
Edwin Ruff, Moses Lake, Wash., built a lawn aerator by welding 130 1/4 by 3-in. bolts to an old 10-gal. tank that he fills with water. He fitted it with 6-in. wheels and wheelbarrow-type handles. "The machine works really well on my lawn and around my sprinkler system," he says.
  An old rope-start 3 hp Briggs and Stratton engine propels the aerator drum forward. "If I let it go, it'll run straight across the ground," he says. "I walk ahead and wait at the end to turn it a different direction."
  A lever disengages the drive belt to put it in neutral.
  Ruff says the biggest challenge was gearing down the engine to a slow walk. He used two gear reductions to do that.
  "To gear it down, I used a chain-driven bicycle wheel as well as a 2-in. pulley and a 12-in. belt-driven pulley."
  Because the original tank full of water wasn't heavy enough, he added another 10-gal. water tank on top that adds more weight.
