Skid Steer Bucket Cutting Edges

A bolt-on cutting edge is a replaceable wear component that attaches to the lip of a skid steer bucket using bolts rather than welding. This design allows operators to quickly replace worn edges in the field without specialized welding equipment or skills. Bolt-on edges typically feature pre-drilled mounting holes that align with threaded inserts or bolt patterns on the bucket lip. This system reduces downtime, lowers maintenance costs, and extends the life of the bucket itself by protecting the base metal from direct wear.

To weld a cutting edge on a bucket, first clean both surfaces thoroughly to remove dirt, rust, and old weld material using a grinder. Position the new edge flush with the bucket lip and tack-weld at several points to hold alignment. Use a continuous bead weld along the entire edge using 7018 or similar low-hydrogen electrodes for structural welds. Weld on both the top and bottom surfaces for maximum strength. Allow the weld to cool slowly to prevent cracking, and grind smooth any sharp edges that could catch material during operation.

Replacement cutting edges are available directly from Maxx Attachments for all our GP Buckets and Conveyor Cleaning Buckets. We supply AR400 bolt-on cutting edges engineered specifically for our bucket models, ensuring perfect fit and optimal performance. Contact our sales team at (316) 722-8710 or through our website to order replacement edges with your bucket model number. We also maintain relationships with equipment dealers throughout the USA who stock our replacement components for immediate availability.

Replacement frequency depends on application intensity and material abrasiveness. In general construction and material handling, inspect edges every 200-300 operating hours. Replace when edge thickness is reduced by 50% or when operational efficiency noticeably decreases. In highly abrasive environments like rock quarries or mining operations, edges may require replacement every 100-150 hours. Regular inspection prevents damage to the bucket base metal, which is far more expensive to repair than proactive edge replacement.

While technically possible, sharpening or rebuilding cutting edges is rarely cost-effective compared to replacement. AR400 steel's extreme hardness makes it difficult to machine or grind effectively without specialized equipment. Build-up welding to restore edge profile often creates heat-affected zones that reduce hardness and wear resistance. Most operators find that the labor cost of rebuilding exceeds the price of new replacement edges. For optimal performance and predictable wear characteristics, manufacturers recommend replacing edges rather than attempting repair.

Straight edges work best for general-purpose material handling, dirt work, and grading applications. Serrated or toothed edges excel at breaking through hard-packed materials, frozen ground, or dense clay by concentrating force at multiple penetration points. Smooth radius edges are ideal for finish grading and working with loose materials like sand or grain. For applications involving rock or demolition debris, consider reinforced edges with additional backing plates. Maxx Attachments can customize edge configurations based on your specific material handling requirements.
