Cat®Pro Series Thumb Highlights

Pro Series Thumb

Cat® Pro Series Thumbs are an asset to any job site — making an excavator and bucket more productive in many different situations. The addition of a thumb upgrades the performance of an excavator by extending its use beyond digging. The bucket and thumb work together, easily grabbing, picking and sorting. Thumbs can be used in a variety of applications, including site preparation, land clearing, site cleanup, forestry and residential demolition.

  • Thumb is controlled independently of the bucket. The operator positions the thumb as needed for precise material handling and placement.
  • Pro Series Thumbs rotate around the bucket pin. The thumb teeth move with the bucket edge, further enhancing operator control.
  • Thumb frame spans the width of the bucket for good control of longer, wider loads (such as limbs or poles.)
  • Inner curve of the thumb frame naturally cradles material. Serrations help hold material firmly.
  • Thumb frames are tough, validated and field proven to last in a range of applications.
