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. Today, Progress Rail supplies Kershaw® MOW equipment, providing machines to all Class I railroads, transit and short lines and contractors around the world.
The Kershaw® 34-7 Horizontal Scarifier scarifies the tie bed with minimum disturbance to the line and surface of the track. The Kershaw® 34-7 Horizontal Scarifier is a self-propelled machine designed to loosen and remove ballast and other debris from the cribs where old ties have been removed. The head design enables the machine to consistently scarify the right amount of ballast for easy tie insertion with a minimum of tie bed disturbance and tamping requirements.
