Key Features
- Genuine OEM Construction — manufactured to Husqvarna's exact dimensional and material specifications, ensuring the same tactile response, thread engagement, and durability as the original knob.
- Drop-In Replacement — engineered to match the original mounting interface on HTC-series floor grinders, allowing straightforward installation without rework or modification.
- Broad HTC Floor Grinder Fitment — confirmed compatible with the HTC420VS, HTC500, HTC950RX, HTC800Classic, and HTC800HDX floor grinders, covering a wide range of the HTC professional grinder lineup.
- Restored Operator Control — a damaged or worn knob compromises the operator's ability to make accurate adjustments; replacing it with this OEM part restores full, positive control of the machine setting it governs.
- Correct Part Identification — cross-reference part number 593420701 against your machine's parts diagram to confirm this is the exact knob position required before ordering.
A knob on a floor grinder serves as a direct operator interface for adjusting or locking a specific machine function — such as a depth setting, handle position, or operational control. When a knob cracks, strips, or breaks, the operator loses the ability to make precise, repeatable adjustments, which can affect both the quality of the finished floor and the safe handling of the machine. Replacing a failed knob promptly with the correct OEM part restores full operator control and keeps the grinder performing as intended.
