Zusammenfassung:	A linkage system for a screed extension includes a mounting plate that includes a mounting plate finger; an upper rail; a lower rail; a height adjustment shaft; a set of slide blocks that are disposed in a channel between the upper rail and the lower rail; a set of linkage arms; an angle of attack adjustment structure that holds the mounting plate finger at an angle; and a set of angle of attack adjustment screws. The height adjustment shaft is configured to adjust a position of the set of slide blocks within the channel and thereby adjust a height of a lower frame of the screed extension. The set of angle of attack adjustment screws are configured adjust the angle of the mounting plate finger and thereby adjust an angle of attack of the lower frame of the screed extension.
