Key Features
- OEM-Matched Power Transfer — Manufactured to Husqvarna's original gear ratio and torque specifications, this gear box delivers the same drive performance as the unit it replaces — no output compromises.
- Direct Bolt-On Replacement — Engineered to match the original mounting configuration on Husqvarna floor saws, this assembly aligns with existing attachment points for a straightforward installation.
- Broad Floor Saw Compatibility — Confirmed fitment across the FS6600, FS6800, FS7000, FS8400, and FS9900 floor saw models, covering a wide range of Husqvarna's heavy-duty flat saw lineup.
- Restored Cutting Performance — A worn or failing gear box causes blade speed inconsistencies, vibration, and loss of drive power. Replacing it with this genuine OEM unit restores smooth, consistent blade engagement on concrete and asphalt cuts.
- Genuine Husqvarna Quality — Sourced directly from Husqvarna as an OEM part, this gear box is built from materials selected to withstand the high-torque, high-cycle demands of professional floor sawing applications.
The gear box on a walk-behind floor saw is responsible for transmitting engine power to the cutting blade at the correct speed and torque, allowing the machine to make controlled, precise cuts through concrete, asphalt, and other hard surfaces. It steps down the high rotational speed of the engine into the lower, higher-torque output needed to drive a diamond blade effectively under load. When the gear box wears or fails, operators typically see reduced blade speed, excessive vibration, unusual noise from the drive assembly, or a complete loss of blade engagement — any of which can halt a job and compromise cut quality.
