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.
