Description

When you’re swapping out rotary cutter blades or rebuilding the whole blade assembly, you need hardware that’ll hold everything tight while you’re cutting through thick brush and tough weeds. This 1-1/8 inch lock washer works with mower blade bolts to keep your blade secure, even when you’re hitting rocks or stumps that would shake loose hardware apart. A good lock washer means fewer trips back to retighten things up.

What You’re Getting

Grade 5 construction that won’t crack or break under heavy vibration
Zinc plating resists rust and corrosion in wet field conditions
Split design creates spring tension to prevent bolt loosening
Proper 1-1/8 inch size for standard rotary cutter blade bolts

Built for Real Farm Work

This lock washer is used in blade bolt kits for rotary cutters, specifically designed for the heavy-duty applications you’ll find on Bush Hog, Hico, and similar rotary mowers. Whether you’re bush-hogging fence rows, cutting hayfields, or maintaining pastures, this washer keeps your blade hardware where it belongs.

Made to Last

The zinc finish helps this washer stand up to the moisture and debris that rotary cutters face every day. Grade 5 steel construction means it won’t lose its spring tension after a few seasons of use, so it keeps doing its job of locking your blade bolt in place.

Good to Know

Always replace lock washers when you’re changing blades or rebuilding the blade assembly—once they’ve been compressed, they don’t provide the same locking force. Make sure your blade bolt threads are clean before assembly, and torque to your equipment manufacturer’s specs for the best results.
