An overload clutch ( 10 ) for a rotating agitation member ( 11 ) for a surface cleaning machine includes a clutch member ( 12 ) connected to the agitation member ( 11 ) to rotate therewith, a coupling member ( 20 ) rotatable relative to the clutch member ( 12 ), and a torque lever ( 40 ) having an end pivotally mounted to the coupling member ( 12 ). The other end of the torque lever ( 40 ) is biased to engage with the clutch member ( 12 ) such that the agitation member ( 11 ) is rotated together with the coupling member ( 20 ) when a torque load from the agitation member ( 11 ) is not greater than a preset level. The torque lever ( 40 ) pivots outward away from the clutch member ( 12 ) and disengages from the clutch member ( 12 ) to disconnect the torque lever ( 40 ) from the clutch member ( 12 ) when the torque load from the agitation member ( 11 ) is greater than the preset level.
