Lawn Boy 73-3550 Snow Blower Driven Pulley

Product Overview:

Transferring rotational motion through the snow blower's drive system, the Lawn Boy 73-3550 Driven Pulley works with the drive belt and related pulley components within the housing and rotor assembly. Its position in the drive arrangement allows belt-driven movement to pass through the connected rotating components on selected snow blower configurations.

Belt-Driven Motion Transfer:

The driven pulley works with the drive belt to carry rotational motion through the snow blower's mechanical drive system. Its position within the housing and rotor assembly allows belt movement to interact with the connected rotating components during operation.

Drive System Operation:

As part of the mechanical drive arrangement, the driven pulley works with the associated belt and rotating components to maintain the intended drive path. Its position within the assembly places it in relation to the bearing assembly, idler components, rotor driver shaft, coupler, and rotor.

Replacement Guidelines:

Replace the Lawn Boy 73-3550 Driven Pulley when physical damage, excessive wear, deformation, or deterioration affects its intended relationship with the drive belt or connected drive components. Inspect the pulley and related drive areas for conditions that could affect rotational movement. Replace the component when it can no longer maintain its intended function within the drive assembly.

Common Signs of Wear:

• Visible cracks, deformation, or physical damage to the pulley.
• Noticeable wear on surfaces that contact the drive belt.
• Damage affecting the pulley's relationship with the drive belt.
• Excessive deterioration around the pulley.
• Irregular operation associated with the connected drive system.

Equipment Compatibility:

The Driven Pulley is documented for selected Lawn Boy snow blower configurations, including applications within the Power Curve snow blower platform. Match the complete snow blower model and applicable parts documentation with part number 73-3550 before purchase, as different production configurations may use different components.

• What should be inspected on the 73-3550 driven pulley during maintenance?

  Inspect the pulley and belt-contact areas for physical damage, deterioration, or wear that could affect its relationship with the drive system.

• How is the 73-3550 different from an idler pulley?

  The 73-3550 is identified as the Driven Pulley, while the idler pulley assembly is listed separately.

• How does the driven pulley work with the snow blower drive belt?

  The driven pulley works with the drive belt to transfer rotational motion through the mechanical drive system and into connected rotating components.

• What can happen if the driven pulley becomes damaged or deformed?

  Damage or deformation can affect the pulley's interaction with the drive belt and connected components, potentially resulting in irregular drive-system operation.

• What should be checked before purchasing the 73-3550 driven pulley?

  Check the part number, drive belt, related pulley components, and surrounding drive assembly against the applicable equipment parts documentation.
