The Kuhn 40210070 free wheel is an original equipment manufacturer (OEM) part designed for specific Kuhn FC series mowers. This essential component functions as a freewheel clutch, allowing the mower's driveline to disengage when the PTO speed drops, preventing damage from inertia. It is a critical safety and operational part, ensuring smooth power transmission and protection for the machinery. Confirmed fitment includes Kuhn FC 300 and FC 300 G models.
