Ja sa v tom moc nevyznam, ale google mi naslo toto:
Winterketten
Winterketten were developed in 1942 for use in winter conditions on the Eastern Front. These were basically a normal track with track extensions that protruded from the ends of the tracks. These are recognizable by the long triangular extensions. These were usually found on the PzKpfw III, PzKpfw IV and StuG III but could also be seen on Hummel, Hornisse and other vehicles.
Ostketten
Ostketten were developed in 1944 for use in the muddy conditions in the Spring and Autumn on the Eastern Front, the Rasputitsa. These were basically a wider track than the usual track which was fitted. There were no triangular extensions, just a wider track. These were for use usually on the PzKpfw IV and StuG III but could also be found on other vehicles. When seen on the PzKpfw IV it looks like a PzKpfw V Panther track on a PzKpfw IV.
Este - som po tom patral a vyapda to tak ze Ostketten mali krasi drapak (asi tretinovy z toho Winterketten).
