Additional information

This traction idler arm assembly mounts in the drive system and includes the idler pulley used to control belt tension. Snowblower traction idler arm assembly 585238401 pivots as the traction control engages, allowing the pulley to tighten or release the traction belt for movement.

If the snowblower slips, hesitates, or fails to move when the traction control is engaged, the idler arm or pulley may be worn or damaged. Squealing noises, uneven belt wear, binding movement, or visible damage to the arm or pulley are common signs replacement is needed.

Disconnect the spark plug wire before starting the repair. Support the belt and pulley as you remove mounting hardware to prevent shifting. Make sure the idler arm pivots freely, the pulley spins smoothly, and all fasteners are tightened securely after installation.
