This 28" high speed propane buffer from Pioneer-Eclipse comes with an 18 HP Kawasaki engine. A 12 volt battery starter comes standard to get the machine started and the pad driver spinning at 1700 RPM before the pad hits the floor. The RokBak deck allows for easy access to install one of our floor polishing pads from a standing position. The adjustable welded handle enables you, the user, to easily maneuver the machine throughout a job site.
