Check out our new Mini Excavator Riddle buckets! We use 1/4" thick AR plate for the teeth, then add a 15 or 30 Manganese Cutting edge tipped with Single or Double point replaceable Tiger teeth, slap a  3 year warranty on it, and let it go to work with the confidence that we won't see it again. Also available is our Mini Excavator Rake bucket (No cutting edge or replaceable teeth, but built from heavier plate) and our Mini Excavator Screen bucket (Bolt-on cutting edge, 1/4 inch AR plate).
Ask about custom spacing! These come stock with 2.5 inch spacing.
