Hydraulic Thumb vs. Mechanical Thumb: Which Should You Choose?
Cost, plumbing requirements, and jobsite efficiency comparison for 1–10 T excavators.
Direct Engineering Summary
Choose a Hydraulic Thumb ($285–$480) if your excavator already has auxiliary hydraulic lines on the dipper stick and you frequently pick and sort rocks, brush, or demolition debris. Choose a Mechanical Rigid Thumb ($180–$260) if your machine lacks auxiliary plumbing or you only need occasional clamping support.

Why Tooth-to-Tine Meshing Matters
When pairing a thumb with a digging or skeleton bucket, the thumb tines should either interlace between the bucket teeth or meet the outer side cutters squarely. Ordering your bucket and thumb together from ATTACORE ensures we match the thumb tine width and length to your exact bucket radius.
