857/877 Carrier Walk-around


Daryl Westerveld, product engineer for tracked harvesting systems, takes us on a walk-around of the 857 and 877 carriers. The sloped tail represents a reimagining of what a steep-slope carrier should look like. The result is a machine with increased leveling capability and greater chain clearance in winch-assisted applications, while maintaining the class leading stability of Tigercat machines. Watch this video to learn about the key features and benefits of owning an 857 and 877 carrier.
