Aftermarket Quadco-style saw teeth, beaver teeth and planer knives for hot saws, feller buncher heads, disc mulchers and mowers, built to OEM fitment so they thread straight into the holder you already run. Kerf sizes run 1-1/8" to 2-3/8" square in one-piece, two-piece and shankless construction (a matching shank for 5/8" teeth is stocked separately), with straight-edged quad-point for clean wood or concave quad-radius for dirty and frozen material, plus carbide tips for abrasive ground. These fit roughly thirty machine brands including Tigercat, Caterpillar, John Deere, Fecon, Loftness and Vail, and around sixty OEM interchange numbers are cross-referenced on the product pages below. Use the Mulching Teeth Search above to filter by machine, or match your worn tooth by kerf, thread and shank; if you have a part number or a photo instead, send it and we'll identify it.
