With the Craze Advent Calendar Claas, a complete playset with stands and buildings is created, just like a DIY kit. The highlight is the Claas tractor, which offers a lot of fun with its movable front loader and cabin attachment. The Claas two-axle trailer features fold-down rear and side walls. Both the tractor and the trailer can be stored in a covered shelter. The tractor and trailer can be played with using a figure.
