Key Features
- OEM-Matched Mass and Geometry — Manufactured to Husqvarna's exact weight and dimensional specifications, this counterweight delivers the precise rotational balance the PG400 grinding head requires.
- Direct Bolt-On Replacement — Engineered to match the original mounting configuration, this counterweight installs directly in place of the factory part with no modifications to the machine.
- Compatible with the PG400 Floor Grinder — Designed specifically for the PG400 planetary floor grinder; cross-reference part number 589837101 against your parts diagram to confirm fitment before ordering.
- Restored Grinding Stability — A correctly weighted grinding head reduces vibration transfer to the machine frame, allowing the PG400 to maintain consistent surface contact and an even grind pattern across the floor.
- Genuine Husqvarna OEM Quality — As a genuine OEM part, the Counterweight meets the same material and finish standards as the component originally installed at the factory, supporting the long-term structural integrity of the grinder.
The counterweight on a planetary floor grinder is a precision-balanced component mounted to the rotating grinding head assembly. Its role is to offset the mass of the grinding tools and satellite heads, keeping rotation smooth and reducing vibration during operation. When a counterweight is missing, damaged, or replaced with an incorrectly weighted substitute, the grinding head runs out of balance — leading to excessive vibration, uneven floor finish, accelerated wear on bearings and drive components, and operator fatigue. Replacing it with the correct OEM part restores the balanced rotation the PG400 was designed to deliver.
