Reconditioned Advance PBU 21KBCAT 21" Propane Burnisher
Our Take (from the SES Sales Team)
“A propane burnisher is built for large hard floors that get burnished on a schedule, like grocery and big-box retail, school corridors and other open areas where a cord slows the crew down. The Advance PBU 21KBCAT spins a 21-inch pad at 2,100 rpm, driven by a 603cc Kawasaki V-Twin engine, so it is a high-gloss maintenance machine for finished floors, not a stripping or scrubbing machine.
Advance built the PBU series with a one-piece cast deck and frame under a powder-coat finish, plus an adjustable handle. The 21KBCAT is the non-dust-control version, which keeps it at 212 pounds, well under the 292 pounds of the dust-control 21KBCATCLDC.
Be realistic about what propane requires: trained operators, good ventilation, regular oil checks and a steady supply of propane cylinders. With no dust control, burnishing dust stays on the floor, so plan for dust mopping afterward. If propane doesn't fit your building, a battery burnisher is the better choice. This is a reconditioned unit, so ask your sales rep what comes with it, such as the propane cylinder and pad driver.”
“Reconditioned machine delivered within the stated timeframe. It looks practically brand new!” — Joshua S., Google review

The Advance PBU 21KBCAT is a walk-behind propane burnisher from Advance's PBU Series 21 & 27 line. It burnishes a 21-inch (53 cm) path at 2,100 rpm, powered by a 603cc Kawasaki V-Twin engine. Advance lists this model with a pad holder and without dust control, at a weight of 212 lb (96 kg).
Advance built the PBU series with a rugged one-piece cast deck and frame and a powder-coat finish that resists damage, plus an adjustable handle for the operator. Within the series, Advance also offered 21-inch and 27-inch dust-control models and versions with catalytic mufflers or CARB Gard emissions control; the 21KBCAT is the 21-inch model without dust control.
