Key Features
- OEM-Matched Gear Tolerances — Manufactured to Husqvarna's original specifications, this assembly delivers the precise gear meshing and torque transfer characteristics the PG680RC and PG820RC were engineered around.
- Direct Drop-In Replacement — Engineered to match the original mounting points and interface connections, this Gearbox Assembly installs directly into the drive system without modification.
- Confirmed Fitment for PG680RC and PG820RC — Verified compatibility with PG680RC and PG820RC planetary floor grinders, so you can order with confidence.
- Restored Drive Performance — A functioning gearbox keeps grinding heads turning at the correct speed and with consistent torque output. Replacing a worn or failed unit restores full grinding capacity and surface quality.
- Long-Term Mechanical Integrity — Genuine OEM construction means internal components — gears, shafts, and housings — are matched to each other from the factory, supporting durable, consistent operation under heavy grinding loads.
The Gearbox Assembly is the core mechanical link between the motor and the grinding heads on a planetary floor grinder. It converts motor output into the correct rotational speed and torque needed to drive the satellite heads across concrete, stone, or coated surfaces. When the gearbox wears or fails, grinding performance drops noticeably — operators may experience uneven head rotation, excessive vibration, or a complete loss of drive to one or more heads. Replacing this assembly with a genuine OEM unit restores the mechanical drive system to its original operating condition and keeps the PG680RC or PG820RC performing as designed.
