Key Features
- OEM Tooth and Material Specification — Manufactured to Husqvarna's exact gear geometry and material hardness standards, ensuring proper load transfer and mesh with mating drivetrain components.
- Direct Drivetrain Replacement — Engineered to mount and mesh exactly as the original, allowing straightforward installation without modification to surrounding components.
- Broad FS-Series Compatibility — Fits a wide range of Husqvarna walk-behind floor saws, including the FS4800, FS5000, FS6600, FS6800, FS7000, FS8400, and FS9900.
- Restored Power Transmission — A correctly functioning gear delivers smooth, consistent power through the drivetrain; a worn or damaged gear causes slippage, noise, and loss of blade control on the cut.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts program, this component meets the same build standards as the original production unit.
The gear in a walk-behind floor saw is a critical drivetrain component responsible for transmitting and, where applicable, reducing rotational force from the engine or motor to the blade drive system. It meshes precisely with adjacent gears or drive components to maintain the correct speed and torque ratio needed for controlled, consistent cutting through concrete and asphalt. When a gear wears, chips, or fails, the drivetrain loses efficiency — resulting in irregular blade speed, abnormal noise, vibration, or a complete loss of drive — making timely replacement essential to maintaining safe and productive cutting operation.
