What It Is

This set of two chipper blade knives is designed for sharp-edge replacement on Troy-Bilt Super Tomahawk chippers and similar models. It fits shredder/chipper machines used for grinding yard waste like branches, leaves, and brush into mulch.

Fitment & Compatibility

Before buying, verify your machine’s model number. This set is listed for Troy-Bilt Super Tomahawk models using OEM numbers 1901824, 1908600, 1900104, 1901303, W2030905, and aftermarket equivalents 47278, 47279, 47282, 47287. Measure your existing blade’s length, width, and mounting hole spacing—these are typically 5.5" long, 1.75" wide, with two holes 3.75" apart center-to-center, but confirm against your old blade. Not all Troy-Bilt chippers use the same blade; check your owner’s manual or the part number stamped on the blade itself. This is an aftermarket part, so it may not match OEM tolerances exactly.

Key Things to Know

• Quality concerns: With a 3.1 rating and only 13 reviews, reports mention inconsistent sharpness, soft metal that dulls quickly, or blades that don’t seat perfectly. Expect potential fitment issues.
• Installation difficulty: Moderate. You’ll need to remove the old blade bolts, often rusted or torqued tight. Use penetrating oil and a breaker bar. Torque new bolts to spec (typically 30-40 ft-lbs). Wear gloves—edges are sharp.
• Common gotchas: Blades may require filing or grinding the mounting holes to align. Always replace both blades as a set for balanced operation. Check the chipper’s flywheel for damage or debris before installing.
• Safety: Disconnect the spark plug before working. The chipper’s rotating assembly can cause serious injury if accidentally engaged.

Should You Buy It

Only if you need a low-cost, quick replacement for a Troy-Bilt Super Tomahawk and are comfortable with possible fitment adjustments or shorter lifespan. For a better match and longer wear, consider OEM blades or a higher-rated aftermarket set. Avoid if you want drop-in precision or heavy-duty use.
