The 420BU is a propane powered, ultra-high speed burnisher that gives floor care professionals the options they want to customize a machine to their needs.

Each model comes standard with a 12-volt on board electric starter and clutch. A passive vacuum and EcoSense emissions monitoring system are optional at extra charge (active vacuum is standard on the 40‰Û_ model).
