ABSTRACT:
Disclosed is a lawn mower having several pairs of rotatable blades attached to a rotatable frame. The rotatable frame is motor driven, and centrifugal forces cause a frictional engagement between blade driving means and a portion of the frame so that each pair of the blades assume a planetary rotary motion, yet are capable of movement away from obstacles.
