发明名称 Ballast plow
摘要 A ballast plow that is attached to a KERSHAW ballast regulator wing. The plow will be attached to the wing so that it can be moved toward and away from the wing, and in addition, it can be moved up and down and can be rotated from side to side. The plow will allow the device to extend its reach to an area outside the normal ballast area of a railroad track and to clear away brush and small trees which might impinge upon the ballast area. The plow reclaims ballast, drainage, and creates an improved walkway, thus providing a safe working area.
