No. 78 Graveler

The huge 12 cubic feet capacity delivers maximum coverage potential for ballast rock applications. The adjustable door dispenses 2 1/2-inch diameter rock down to pea gravel. The rock is discharged behind the large balloon tires, eliminating membrane punctures and excessive insulation compaction. The inset tires allow dispensing of rock next to the previous row without running over rock. Self-propelled and extremely maneuverable, the No. 78 is the most efficient ballast spreading machine available today.
