HUSQVARNA / MODEL FAMILY
ST 224 family (970528602 / 961930096)
24-inch ST 224 family with multiple Husqvarna SKUs/generations. Current North American SKU 970528602 and legacy SKU family 961930096 are not treated as interchangeable repair identities.

Troubleshooting coverage here is explicitly scoped to current North American SKU 970528602; support-listed SKUs 970468501 and 961930096 remain identity-only until their exact manual revisions are selected.
- Current ST 224 NA product SKU is 970 52 86-02 (970528602) and Husqvarna lists 12.9 cu.inch displacement with friction-disc transmission.
- Husqvarna support currently also exposes SKU 970 46 85-01 (970468501) alongside 970528602 and legacy 961930096; no 970468501 repair procedure is treated as interchangeable until its exact manual is selected.
- Husqvarna support retains legacy ST 224 SKU 961 93 00-96 (961930096) with 12.7 cu.inch displacement. The shared ST 224 marketing name therefore does not prove the engine/manual generation.
- Do not apply a current 970528602 adjustment or part assumption to 970468501 or 961930096 solely because all say ST 224 on the housing.
SKU / GENERATION RESOLVER
Which ST 224 family (970528602 / 961930096) generation is on the label?
The marketing name can survive across different product numbers. Pick the exact SKU/article number before opening a repair path.
Do not infer the generation from “ST 224” alone.

Use the serial resolver first where ranges are shown. The form number is a compatibility clue, not a substitute for the product label.
Use this hub only after the model matches
The guides below share a model family, not a generic snowblower template. Start with the symptom that best matches what the machine is doing now. If the product label or serial range does not match the source note above, return to the brand index instead of borrowing an adjustment or part assumption from a nearby model.
For a symptom that changed after an impact, freeze-up, storage period or prior repair, preserve that history while diagnosing. A model-specific page is most useful when the exact failure pattern is kept intact rather than replacing several parts at once.
