Video - Half-tracked Linn trucks
Today, during searching of information about Alfa Romeo trucks, I have found an interesting live journal community about half-tracked trucks. These two videos show old semi-tracked Linn trucks in action in career and snow plow operation in the late 20s. In the second video, at the very beginning, you can see the interesting process of greasing tracks of truck. Because the friction in the mechanism was really terrific, this procedure had to be repeated every 8 hours.
