Title:
Kubota Pin, Blade
Description:
The KU-K545334590 blade pin is a genuine Kubota mower deck shear/retaining pin used to secure the cutting blade to the spindle assembly. It is designed to hold the blade firmly in position while allowing controlled failure under excessive load, protecting the mower deck and drivetrain components from damage.
Often referred to as a blade shear pin, it acts as a safety component—shearing or deforming if the blade strikes a solid object, helping to prevent costly mechanical failures.
