  • Patent number: 11913241
    Abstract: A ride-on floor machine, including: a frame including a lower frame portion; a drive system carried by the frame; and a blade control system carried by the lower frame portion, the blade control system including: a blade holder pivotably attached proximate a front end of the lower frame portion; and a linear actuator coupled to the blade holder at a first end and coupled to the lower frame portion at a second end, wherein the actuator extends along a center line parallel to the lower frame portion and is operative to move between an extended position where the blade holder is in an up position and a retracted position where the blade holder is in a down position.

  • Patent number: 11680682
    Abstract: An overload control device for use with a floor machine having an electric motor is disclosed. The overload control device can include a power input and a power output connectable to the electric motor. The device can include a load detector, a current sensor operative to sense a current value supplied to the motor via the power output, and a cutoff relay interconnecting the power input and the power output. The cutoff relay being operative to supply power from the power input to the power output when activated, and interrupt power when deactivated. A controller receives a load present indication from the load detector and activates the cutoff relay if a load is present. The controller receives a current value from the current sensor, determines if the current value is greater than a threshold value, and deactivates the cutoff relay when the current value is greater than the threshold value.
