The Husqvarna 580909801 Start Capacitor is a genuine OEM electrical component designed for the PG400 floor grinder. As an authentic Husqvarna part, it is manufactured to the exact capacitance and voltage ratings required by the PG400's motor, ensuring correct startup behavior every time the machine is switched on. DHS Equipment supplies this part to help keep your floor grinder operating at full capacity. Cross-reference part number 580909801 against your parts diagram to confirm fitment before ordering.
Key Features
- Correct Capacitance Rating — Manufactured to the precise electrical specification required by the PG400 motor, delivering the startup torque the machine is engineered for.
- Genuine OEM Component — Sourced directly from Husqvarna, this capacitor matches the original unit in physical dimensions and terminal configuration for a direct swap installation.
- PG400 Floor Grinder Fitment — Verified fit for the Husqvarna PG400 planetary floor grinder; always verify against your parts diagram using part number 580909801.
- Restored Motor Startup Performance — A failed or degraded start capacitor causes sluggish starts, motor humming, or failure to turn over; replacing it with this OEM unit restores clean, reliable ignition of the drive motor.
- Electrical Safety Compliance — Using the correct-rated capacitor prevents motor overload and overheating during startup, protecting both the motor windings and the operator from the consequences of an undersized or mismatched component.
A start capacitor provides the initial surge of electrical energy needed to generate enough torque to get the motor spinning from a standstill. Once the motor reaches operating speed, the capacitor's role is complete for that cycle. When this component degrades or fails, the motor may struggle to start, draw excessive current, hum without turning over, or trip a breaker — all of which halt production and can place additional stress on the motor windings over time. Replacing a worn start capacitor with the correct OEM-rated unit restores proper startup behavior and protects the motor from the strain caused by repeated failed start attempts.
