ABSTRACT:
There is disclosed a mobile machine for plowing railroad ballast. Mounted centrally of the machine between the front and rear axles thereof and beneath the main chassis of the machine are a pair of plow blades. The plow blades are each mounted on an individual sub-frame which is capable of being raised and lowered so that each plow blade may be brought into engagement with the ballast and lifted therefrom for track travel. Each plow blade carries a rail embracing tunnel. A pivotal connection including a parallelogram linkage connects both tunnel and plow blade to their respective sub-frames such that the blades can be moved through a wide arc in a vertical plane, their tunnels being capable of spanning the rails in each position adopted by the plow blades.
