Variants and what to check
The Advenger parts list (form 56042495) lists two brushes per deck. The parts list does not state disc diameters; dealers describe the 28 in-deck family as 13 or 14 in. The parts list's brush selector guide also explains fills: 46 grit most aggressive, 80 grit general stripping, 180 grit daily cleaning of hard-finished floors, soft nylon for soft-finish floors.
What to send us for a quote
- Outer diameter of the brush or pad driver, measured across the bristle tips.
- The drive hub on top: clutch-plate type, number of lugs, or the hole pattern — a clear photo is usually enough.
- Trim length (how far the bristles stick out of the block) and the current fill: polypropylene, nylon or abrasive grit.
- For cylindrical decks: overall length, core diameter and the shape of the drive ends.
- Your machine model (Advance Advenger) and, if you have it, the OEM part number from the old brush.
