The Durabuilt 5500 series includes all the best features of the 3500 series and adds more rubber and more steel to meet the most demanding applications. These features include more inner surface rubber and bias layers for improved protection from carcass tearing. Also, the 5500 series offers more tread and guide lug material for increased wear life. This series of track is recommended for use in demanding agricultural applications where roading and/or side slope operations are common. For construction applications, we offer two specific tracks in 30" and 36" widths optimized for scraper pan pulling.
