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 branches from railroad right-of-way. It is capable of cutting up to 30 ft. (9144 mm) from the track center, and leaves behind a biodegradable mulch.
Frame: Welded construction of side frame member and formed plate cross-members.
Weight: 62,000 lb. (28123.2 kg)
Engine: Caterpillar C9 Tier III rated for 300 hp @ 2200 rpm.
Propel System: Closed loop variable displacement axial piston pump driving a fixed displacement axial piston motor. Maximum travel speed is 35 mph with full time four wheel drive.
Transmission and Axle: Hydrostatic transmission drives a 4 speed gear box. Front and rear automotive type axles with automatic positive locking differentials are driven through cardan shafts with slip joints.
Wheel and Brakes: 28 inch cast steel wheels are bolted to axle hubs. 4-wheel clasp brakes are axle mounted. Service brakes are air applied and spring released. Parking brakes are spring applied and air released. Suspension system utilizes coil springs.
Air System: Air compressor, engine oil lubricated, air cooled; 13 cu. ft free air volume @ 2200 rpm; system pressure 100 psi; 613 cu. in. air tank. Air is supplied to service brakes through a pressure reducing valve with pressure gauge. Parking brake is set by means of a electrically activated air dump valve. System is also equipped with dual tone air horns and a safety relief valve.
Hydraulic System: The engine drives a triple pump drive through a clutch. Two triple pumps power the cutter motors and the cutter head control circuits.
Electrical System: 24 volts dc negative ground; 95 amp alternator; color coded and numbered wiring.
Cab: The cab accommodates two operators (one for each cutterhead). Adequate height is provided for standing at entry door and rear section. Each operator has a set of foot pedals for controlling direction. The cab is equipped with heater, air conditioner, and a pressurization unit. Cab side walls are double wall construction (1/4” A514 over 11 ga.) with Lexan® marguard windows.
Capacities: Fuel tank: 110 gallons. Hydraulic tank: 100 gallons.
Cutterhead: Booms can rotate a 10 ft. wide double disk cutterhead outboard up to 30 ft. from rail centerline and 45° up/40° down from horizontal. Single boom operation is made possible by shifting a counterweight hydraulically to opposite side of the live cutterhead.
Turntable System: The Brushcutter has a turntable and can be turned manually.
Controls: Two 5-section valves (one for each operator) control the functions of the respective cutterheads. Boom in/out, up/down. and cutterhead pitch, tilt, and rotate are controlled by these valves. Travel direction is controlled by hydraulic foot pedals at each operator position.
