Kershaw 44-2 Rotary Scarifier


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.

Our Kershaw Model 44-2 Rotary Scarifier meets requirements of MOW operationsthat prefer the rotary head method to prepare the tie bed for tie insertion. This self-propelled unit removes ballast, wood chips and other debris from cribs where old ties have been removed.


Technical Details


• Three rotary toothed drums scarify between the rails and adjacent to the outer edge for clearing a width of 9 feet, 5 inches with the standard head.

• A standard equipment extension pivots into position and extends the digging capability on one side of the head, out to 6 feet, 3 inches from the track centerline, or 12 feet, 6 inches overall scarifying width.

• An optional additional extension provides a total of 7 feet, 5 inches from the track centerline—or an overall digging width of 14 feet, 10 inches by using all of the extensions on both sides of the head.

• On the standard head, three rotary-toothed drums scarify between the rails and adjacent to the outer edge of the rails. The rotary drums feature double-row, tapered roller bearings for long bearing life.

• An optional hydraulically powered winch and special attachment allows on-the-spot tie insertion.

• The digging diameter is 21 inches. The drums can turn clockwise or counterclockwise direction at the choice of the operator.

• An optional feature allows cemented material left under the rail area to be removed by kicker feet located on the optional tie sweep assembly.
