Purchasing Notes:

2. Confirm Arc Radius & Bevel Type: Confirm bevel option according to actual working conditions.

3. Reject Welded Spliced Blade: Qualified curved grader blade must be one-piece bent. Welded arc blades are prone to cracking under cyclic load and cannot be used for formal engineering.

4. Insist Full Through-Hardening: Surface-hardened blades will cause rapid wear and edge bending in fine grading work.

5. Verify Hole Pattern & Thickness: Curved blade hole layout is different from flat blade, so they are not interchangeable..

6. Warranty Exclusion: The blade breakage or deformation caused by heavy rock impact, overload and improper installation are not covered by our warranty.
