Abstract: A hood assembly for a mobile excavator has a lever arrangement by means of which the hood which--with respect to the driving direction--is arranged behind the driver's cab, can be swivelled up. The hood has a first projecting end wall which is directed toward the driver's cab and which has a set-off area with respect to a second set-back end wall. Both end walls have a course along oblique planes which extend at an acute angle with respect to the body and which are arranged approximately in parallel to one another. Outer side levers and a center lever, which is arranged in-between, of the lever arrangement form a four-bar mechanism with the hood by way of which the lower boundary edges of the end walls during the swivelling in the overlapping area with the driver's cab and a tank can be moved within a gap as well as along a front wall of the tank on a straight course along the planes.
