This paper presents dynamic stability simulation tests of the Ł34 dynamic loader. The simulations were run according to military standards of United States of America. Tested loader had to overcome two obstacles at a first gear velocity. The first obstacle were pothole, while second one were rut. The current obstacles were crossed by Ł34 loader with two configurations. The first of them were loader in transport configuration, whereas second one were loader with maximum lift height of the bucket. The crossing of the rut was performed only by the loader in transport configuration, whereas passing of the pothole was performed by the loader in both configurations. The two obstacles also were crossed by loader with a nominal load and without it. This paper also defines effects of the modification of loader with more stiffer and more flexible tyres. There were also consider effects of the modification of Ł34 loader with integrated articulation.
