FITMENT & BUCKET CLASS INFORMATION
Fitment & Bucket Class Information
Excavator tonnage is a guide only.
Bucket build class, compatibility, and pricing are determined by the machine’s pickup configuration, including:
- Pin diameter
- Pin centres
- Width between ears
- Quick hitch configuration
Machines with larger pin sizes require heavier-duty bucket construction with increased material thickness and reinforcement, even where machine tonnage may overlap other classes.
This ensures correct fitment, strength, durability, and long-term performance.
Some machines may vary from standard specifications depending on hitch setup and manufacturer configuration.
