Progress Rail’s Maintenance-of-Way (MOW) division was born out of the movement toward mechanization in the railroad industry and introduced the first Kershaw Ballast Regulator in 1945.
As a global supplier of Kershaw MOW, utility and vegetation management equipment, we provide a comprehensive line of machines to help maintain rail infrastructure and right-of-ways around the world.
The Kershaw Model 32-10 Brushcutter clears brush and overhanging tree branches from railroad right-of-ways. The Model 32-10 Brushcutter has two independently controlled booms attached to each side. A 10-foot wide cutter head is attached to the end of each boom, and can extend from zero to 90 degrees and lift up to 45 degrees from a horizontal position, or 40 degrees below. The machine is capable of cutting a 10-foot swath up to 30-feet from the track center on each side and leaves behind biodegradable mulch..
