A screed has an extendible frame portion that includes a catch engaging surface of an extension mounting system. The extendible frame portion is expandable along a lateral extension axis and pivotable about a pivot axis perpendicular to the lateral extension axis. A screed extension has a screed extension frame supporting a mounting catch of the extension mounting system. In a mounting configuration, the extendible frame portion is pivoted to a lowered mounting position, and the extendible frame portion is axially expanded to an extended mounting position in which the catch engaging surface and the mounting catch are vertically aligned. In a lifted configuration, the extendible frame portion is pivoted to a raised lifting position, the catch engaging surface and the mounting catch are in mating engagement, and the screed extension is supported on the extendible frame portion using the extension mounting system.
