[AT] Replacement teeth for lawn aerators

[Herbert Metz]

    Golly, have had little results in my finding 3/4" O.D., round, hollow replacement teeth for a lawn aerator.    Teeth are stamped from .060" sheet metal, then formed into a reasonably decent round tube.      Origonal teeth are 4 3/16" long; the only replacements I have found are 5 1/4" long.     My opinion is the longer teeth are more likely to break off.     I need at least 30 replacement teeth for this 4' wide rolling aerator.    Best price to date is decent  ($3 plus shipping); buy considerable time will be spent  recutting/shortening the work end of the tooth.  Anyone know of a better source?
