Variants and what to check
All BD 43/25 C versions (Classic Bp, Bp Pack with lithium or AGM battery) share the 430 mm disc size. The pad drive board is smaller (403 mm) than the brush and carries 432 mm (17 in) pads. When ordering a replacement disc, check the centre plate/coupling on your old brush, as Kärcher uses its own quick-change fitting.
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 (Kärcher BD 43/25 C) and, if you have it, the OEM part number from the old brush.
