This was mentioned to me by a mechanic at our dealership, and he said a few lco's in the area have been doing it, so I thought I would give it a try. One of the problems with going over some areas at high speeds, is that the deck starts bouncing. With the right terrain and the right speeds, the deck can even start "dribbling" as the frequency is reached that it bounces radically. All you can do at that point is slow down. Well, what I tried was to wrap the chains in duct tape. This gives rigidity and firmness to the chains and controls the deck from bouncing like that. It stabilizes it and gives better control and less noise and bouncing. I can't believe the difference this makes. It still has give when needed for contour and terrain change, but doesn't flutter at higher speeds - especially on rougher ground.
