The mower safety device includes a tensioning element (1) for the endless belt (2) driving the shaft of the cutter blade (3). The tensioning element is mounted on a spring loaded lever (4) which is supported at its other end by the grass box of the mower. The braking lever has a curved band (7) attached to its free end which passes around the hub of the cutting blade. When the grass box is removed from the mower the security device locks the blade to prevent rotation.
