Key Features
- Genuine OEM Spring Specification — manufactured to Husqvarna's exact tension and travel tolerances, ensuring the throttle trigger engages and releases with the precise feel the original design requires.
- Direct Drop-In Replacement — engineered to mate with the existing throttle trigger assembly on K950, K960, and K950Rescue power cutters without additional hardware or modification.
- Broad K-Series Compatibility — a single part covers the K950, K960, and K950Rescue, making it the correct solution for the most widely used models in Husqvarna's professional power cutter lineup.
- Restored Throttle Response — a correctly functioning spring returns the trigger fully and consistently, maintaining smooth, predictable power delivery and preventing unintended blade engagement.
- Operator Safety — a worn or broken throttle return spring can cause the trigger to stick or fail to return to idle, creating a hazardous condition during active cutting. Replacing it with an OEM-spec part restores the safety behavior the machine was designed to deliver.
The Spring Throttle Trigger is the small but critical component that returns the throttle control to its idle position the moment the operator releases pressure. It works in conjunction with the trigger assembly to regulate engine speed and ensure the blade does not remain at cutting speed unintentionally. When this spring weakens, deforms, or breaks, the throttle may stick, respond sluggishly, or fail to return to idle — compromising both control and operator safety on the cut.
