Abstract: A knee link flail system for neutralization of landmines consisting of a rotatable shaft mounted on a carriage with flat structures attached perpendicular to the shaft at predetermined intervals. A plurality of first legs are connected to outer edges of the flat structures via first rotatable connections. A plurality of second legs, each being connected to an outer end of an associated first leg via a rotatable connection. A hammer mass is attached to an outer end of each second leg that impacts against a soil's surface upon rotation of the rotatable shaft.
