Gentec Hydraulic Weld-On Excavator Thumb | 4,000–9,900 lb Machines

Regular price $1,360.00
Brand: Gentec Equipment

The Gentec Hydraulic Weld-On Excavator Thumb gives compact excavators a better grip on logs, rocks, brush, demolition debris, and other loose or irregular material. It works with the excavator bucket to grab, hold, sort, and position material that is difficult to manage with the bucket alone.

Hydraulic operation lets the operator control the thumb from the cab, making it a practical upgrade for contractors, landscapers, farmers, and property owners handling land clearing, site cleanup, forestry work, and light demolition.

Choose between a 24" or 30" thumb based on your excavator, bucket, and coupler setup. The longer HT830 may be needed on machines equipped with certain quick couplers or pin-grabber couplers.

Best for: Handling brush, logs, rocks, construction debris, and land-clearing material.

Quick fit check: Designed for excavators weighing approximately 4,000–9,900 lb, depending on the selected model. Auxiliary hydraulics and professional weld-on installation are required.
