Abstract: A system for controlling heating of a screed plate includes screed plate disposed along the paving material delivery path. A first temperature sensor is operative to monitor a screed plate temperature and a second temperature sensor along the paving material delivery path is operative to monitor an actual paving material temperature of a paving material being applied to a work surface. A controller is configured to determine an estimated paving material temperature adjacent the screed plate based upon the actual paving material temperature and operate a heater to maintain the screed plate temperature within a temperature variation range relative to the estimated paving material temperature.

Abstract: An auger segment can comprise a base having a first end, a second end opposite the first end in a length direction of the base, a first side, and a second side opposite the first side; a first receptacle projecting from the first side of the base; a second receptacle projecting from the first side of the base; and a flight projecting from the first side of the base between the first receptacle and the second receptacle. A first recess of the first receptacle can be defined by a first sidewall thereof and a second recess of the second receptacle can be defined by a second sidewall thereof. A first through hole can extend through the base in the first recess of the first receptacle and a second through hole can extend through the base in the second recess of the second receptacle.

Abstract: A screed assembly is disclosed. The screed assembly has a screed frame that includes a main screed. Attached to the main screed is a drop arm that is used to attach the screed assembly to a work machine. An actuator device of the screed assembly adjust the main screed from a neutral position to a nulled position by rotating the main screed around an axis of the pivot pin. The screed assembly may further include a controller that determines whether the main screed is in the neutral position and adjust the main screed to the nulled position by sending a null adjustment signal to the actuator device, and the actuator device moving the main screed from the neutral position to the nulled position in response to the null adjustment signal.
