Just finished aerating 62,000 sq. ft. of yard for a guy. 24,000 sq. ft. of lawn and 38,000 sq. ft. of LAMA PASTURE WITH THE LAMAS STILL IN THE PASTURE!!!!! He wanted the pasture double aerated because it was really compacted by the darn LAMAS. And these animals walked along side of me while aerating the whole time! What a hoot. jim If the grass is greener on the other side of the fence then just move the darn fence.
