A SoftTrack Skidgine is all about the suspension system: Most track vehicles, like a bulldozer, have nothing or very little in the way of suspension and therefore, the tracks do not move up and down over rough terrain. When a track vehicle maneuvers, it has a tendency to push whatever is in the way out of the way, and thus makes a mess of the terrain it is operating on. On a construction site this doesn’t matter, the damage is eventually repaired in the landscaping phase. But during a wildfire, vegetation is burned away and will not re-grow where the top soil has been removed. In hilly or rugged country this destruction of soil, combined with later erosion, can cause lots of problems environmentally. Lines created by dozers can turn into a path-of-least-resistance for water runoff, bringing dangerous silt into lower lakes, rivers, and ponds, potentially creating mudslides or harming nearby wildlife in the process.

Enter the SoftTrack Skidgine. The soft tracks float over the terrain with very little ground compaction, resulting in far less environmentally destructive vehicle than a dozer. SoftTract Skidgines also maintain better traction than rubber-tired Skidgines: When operating in rugged or steep terrain, rubber-tired Skidgines tend to spin out, digging ruts that further increase the risk of erosion and later mudslides. The SoftTrack Skidgine rolls right around those issues, making it excellent for initial attack situations and interfacing with both urban and rural environments. The SoftTrack Skidgine goes where other conventional machinery simply cannot.

Our SoftTrack Skidgine is powered with a 220HP Detroit Diesel 6V53N and also comes equipped with a 9HP 150psi Two Stage main pump, 450psi multi-stage pump, onboard water cannon, Robwen foam proportion system (Class A & B foam), BB4 20HP 1620 gallon water capacity (which can be filled via helicopter), has multiple hose systems, top speeds of up to 20 miles per hour, and MORE.
