Husqvarna • Snow Blower • Parts reference
This page lists the Husqvarna part numbers for four auger-system components on the Husqvarna ST 224 two-stage snow blower, SKU 961 93 00-96: the drive belt, the impeller belt, the lower auger belt guide and the shear bolt. Every number was checked against Husqvarna's own parts data. Some parts changed between production revisions, so each entry shows which revisions it applies to.
Part number vs. product SKU. The numbers in the table below are component part numbers from Husqvarna's illustrated parts list. 961 93 00-96 is the product number (SKU) for the complete ST 224 snow blower, not a part number.
What is covered. Only the four components below, only for SKU 961 93 00-96. This is not a complete parts list for the machine. For oil, spark plug and lubrication specs, see the Husqvarna ST224 maintenance specs .
The "Applies to" column comes from Husqvarna's own revision notes, which identify ST 224 builds by 11-digit manufacturing ID (96193009601 through 96193009606 for this SKU).

Husqvarna lists this belt as the drive belt in the chassis, engine and pulleys drawings. In the operator's manual the drive belt is the traction drive belt, handled separately from the auger belt. It is listed here because the manual recommends replacing the drive belt and auger belt at the same time.
Husqvarna's spare-part listing describes this belt as a low crank impeller belt. It appears in the same chassis drawings as the lower auger belt guide. The operator's manual does not use the term impeller belt: its belt procedures refer to the auger belt, the belt engaged by the auger control. Husqvarna's documents do not explicitly equate the two names, so order by part number rather than by name.
Husqvarna's internal description, GUIDE.LOWER.AUGER.BELT, identifies it as the lower guide for the auger belt. It is a guide, not a belt.
The auger and impeller shear pins (Husqvarna's parts data calls them shear bolts) are designed to break if an object gets into the moving parts, which protects the machine from damage. The operator's manual says to use only original-equipment shear pins.
Summarized from the ST 224 / ST 227 / ST 230 operator's manual. Follow the manual's full procedures and safety steps. Before replacing a shear pin, for example, the manual says to stop the engine, wait for moving parts to stop, remove the ON/OFF key and disconnect the spark plug cable.
Possible cause: The belt is off the pulley.
Manual's solution: Check or reinstall the belt. Adjust the pulley.
Possible cause: The chute deflector is clogged.
Manual's solution: Clean the chute deflector.
Possible cause: Foreign objects clog the augers.
Manual's solution: Remove the debris or foreign object from the augers.
Possible cause: The shear pin is broken.
Manual's solution: Replace the broken shear pin.
Possible cause: Auger control cable tension. The manual notes this adjustment may also be needed after the auger belt is replaced.
Manual's solution: Adjust the auger control cable. If adjustment does not resolve the problem, replace the auger belt.
Possible cause: Auger control cable adjustment. The manual's check: an assistant times how long the auger takes to stop after the lever is released.
Manual's solution: Adjust the cable and re-test until the auger stops in less than 5 seconds.
