Utility Thumb

You can position and move the Utility Hydraulic Thumb from the cab. As the name implies, this hydraulic thumb is utilitarian in design, with a narrow width and lighter weight. They are most suitable for light to medium-duty material handling tasks where tooth mesh and full rotation are not critical requirements. Because they are not necessarily bucket or machine specific, they are well-suited for use in fleets with a mix of machines and various bucket and coupler combinations.

  • Thumb is controlled independently of the bucket. The operator positions the thumb as needed for precise material handling and placement.
  • One thumb works well with a wide range of machine, bucket and coupler combinations making them perfect for mixed fleets.
  • Utility thumbs mount to the face of the excavator stick allowing for a wide range of machine, bucket and coupler combinations.
  • Utility thumbs are narrow in width for good visibility. They are well-suited for light- to medium-duty tasks like handling brush, rocks, and construction debris.
