UNDERCUTTING WITH EXCAVATORS AND BACKHOES
The DymaxRail Ballast Blaster undercutter attachment features advanced patented design and durability. A Ballast Blaster undercutter efficiently removes fouled ballast rock and mud by cutting and pulling the material out from beneath the railway tracks. This attachment adapts to railway excavators and backhoe loaders equipped with a tiltrotator coupler system.
BLASTER WEAR PLATES
Our patented Ballast Blaster Undercutter features bolt-on indexable wear plates with full carbide protection that surrounds all sides of the cutter bar and includes a 2 year warranty.
BI-DIRECTIONAL CUTTING
A DymaxRail Ballast Blaster cuts and removes ballast faster with its innovative chain design. The Dymax Carbide Tooth (DCT) features two-sided protection, allowing operators to cut in both directions.
