Checking Double-Disk Blade Wear

Disengage inside scrapers. Check by holding one blade stationary and rotating the other one. Blades must have slight contact at point (A) and turn freely.

Most new openers need two or three shims (B) on each disk hub bolt (C) while worn blades may require less. If disk adjustment or replacement is needed, see REPLACING AND ADJUSTING DOUBLE-DISK BLADES (ALUMINUM BOOT) in Service section or REPLACING AND ADJUSTING DOUBLE-DISK BLADES (CAST IRON BOOT) in Service section.
