US Patent 6981819 Tilting screed

A screed plate includes a pair of handles mounted to a pivot member. The pivot member is connected for rotation with respect to a screed plate about a horizontal axis with respect to a screed plate. The vibrator is provided on the screed plate and a tilt actuator is connected to the pivot member and to the screed plate for causing tilting of the screed plate. A laser receiver receives a horizontal laser beam and determines whether or not the receiver is above, below, or at the same level as the laser beam. If the receiver is either above or below the laser beam it sends a signal to the tilt actuator to cause tilting of the screed plate.
