Progressive-Linkage Thumb

The progressive linkage (pro-link) hydraulic thumb provides up to 180° of rotation, allowing operators to pick up and place rocks, tree stumps, pipes and other odd-shaped objects closer to the excavator.

  • Universal pivot linkage system enables it to be installed on any excavator arm without requiring the removal of the dipper arm linkage
  • High-strength steel, rigid structure and oversized high-profile pivot pin increase torsion resistance
  • Integrated linkage positional stops protect the hydraulic cylinder from damage
  • Lock-up pin enables operators to safely secure the thumb in a storage position when not in use
  • Induction-hardened-chrome hydraulic cylinder rod
