What It Does:

Blade shear pins provide shock load protection to the mower deck drive system. These pins are designed as a sacrificial safety component that will break when the blade strikes a solid object like a rock or root, protecting more expensive components such as the spindle assembly, gearbox, and drive system from damage. When properly installed, the shear pin allows the blade to slip or break free under extreme impact, preventing costly repairs to the mower deck.

Installation Note:

The blade washer is used to put tension on the blade and help prevent blade slippage. Proper torque specifications should be followed during installation to ensure the shear pin functions as designed.

This is a wear item that should be kept on hand as a spare part for quick field repairs. Using genuine OEM parts ensures proper fit and maintains the life of your equipment.
