How to Identify When It’s Time to Replace Loader Cutting Edges?

A worn loader cutting edge can reduce efficiency, increase fuel consumption, and damage your bucket. Here are the key signs it’s time to replace:

1. Thinning: If the edge is less than 50% of its original thickness (check with a卡尺), it’s no longer effective at digging. Thin edges bend easily and can’t handle heavy loads.

2. Cracks or Breaks: Small cracks can spread quickly, leading to a broken edge. If you see any cracks (even tiny ones), replace the edge immediately—broken edges can damage the bucket or cause accidents.

3. Dullness: A dull edge requires more force to dig, which increases fuel use and wears out the loader’s hydraulics. You’ll notice this if your loader takes longer to fill the bucket or if it “bounces” off hard material.

4. Uneven Wear: If one side of the edge is worn more than the other, it’s a sign of misalignment. This can cause the bucket to dig unevenly and damage the edge further. Replace the edge and check the bucket’s alignment.

5. Bolt Damage: Loose or broken bolts mean the edge isn’t secured properly. This can cause the edge to shift, leading to uneven wear or damage to the bucket. Replace the bolts first—if the edge is still loose, it’s time for a new one.

6. Bucket Wear: If the bucket’s bottom is wearing out (you can see the metal thinning), it means the edge isn’t protecting it anymore. Replace the edge to prevent costly bucket repairs.

A good rule of thumb: replace loader cutting edges every 500–1,000 hours of use (depending on the job). Regular inspections will help you catch wear early and avoid downtime.
