Funkewagen, signals car, in Lapland 1941.

Signals

The &quot;plow on the Tiger is not a snowplow to clear a road, but to enable the Tiger to move in the snow. Without it the front of the hull will pack snow under the center of the tank. the Tiger will move forward packing more and more snow under it until the snow supports more of the tank's weight than the track uses for traction. When it reaches this point the tank stops moving forward and the tracks just spin. The vehicle is stuck unti the snow is dug out or the tank is pulled off the packed snow. 

The plow diverts the snow from the hull to be packed under the tracks, keeping the weight of the Tiger on its track and not the hull botom. The tank can keep moving forward or backwards in its own path. Unknown date or location
