Genuine Grasshopper - Arm - Idler Upper - 643062

Care & Installation

Steering or control-actuation component (arm, actuator, stabilizer, pivot). Check for play, binding, or uneven resistance through the full range of travel after installation, and grease pivot points per the service manual's lubrication schedule. A worn component here often presents as looseness or drift at the steering control rather than a visibly broken part.
