厂商原文

Ballast the easy way with this handy tool.  It can be towed or pushed by your locomotive for steady and even application. Adjustable height setting allows you to choose ballast depth/thickness and adapts to any code rail (Code 100, 83, 75, etc.). Shutoff valve lets you stop ballast flow when you want to move spreader to different areas or when it reaches the end of track.
