Description

When you’re processing brush, logs, or debris in your tub grinder, those cutting knives take a real beating. Rocks, dirt, and tough wood can dull or chip even the best blades, and when that happens, your grinder starts working harder and producing lower-quality material. This outer knife gets you back to clean, efficient cutting so your operation keeps moving.

What You’re Getting

Heavy-duty 3/16 inch 4150 alloy steel construction that stands up to impact and wear
Tungsten carbide coating on the wear area extends blade life significantly
Precise fit designed specifically for Laird tub grinder systems
Direct replacement for L111—no modifications needed

Built for Tough Processing Work

This knife is engineered for the demanding world of wood waste processing, land clearing, and biomass production. Whether you’re grinding storm debris, processing forestry waste, or turning brush into mulch, it’s built to handle the abrasive conditions that come with the job.

Made to Last

The 4150 alloy steel base gives you the strength to handle impact from knots and foreign objects, while the tungsten carbide coating protects the cutting edge where it matters most. This combination means fewer knife changes and more productive hours between maintenance stops.

Installation Notes

This is a direct bolt-in replacement that uses your existing hardware and mounting setup. Always check knife clearances and rotor balance when replacing individual knives. For best results, replace knives in sets to maintain even cutting performance.
