Variants and what to check
Convertamatic model numbers carry width and deck type (D disc, C cylindrical). Dealers also list a 12 in 3-lug Prolene disc (56505754) for Convertamatic 240LX and a 16 in grit brush (56505781) for 'Convertamatic 32', so older LX/numbered variants may take different brushes. Read the part number on the old brush before ordering.
What to send us for a quote

- 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 Convertamatic) and, if you have it, the OEM part number from the old brush.
