The Gentec Mechanical Weld-On Excavator Thumb gives compact excavators a better way to grab, hold, sort, and move logs, rocks, brush, concrete, demolition debris, and other irregular material.

Unlike a hydraulic thumb, this model is manually positioned using the adjustable linkage. That makes it a practical, lower-cost option for operators who don’t have auxiliary hydraulics or only need a thumb occasionally. Three working positions allow the thumb to be adjusted for different jobs, and it folds against the excavator stick when it isn’t being used.

Choose between the 24" MT824 and 30" MT830 based on your excavator, bucket geometry, and coupler setup. The longer model may be needed when additional reach is required to properly meet the bucket.

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

Quick fit check: Designed for excavators weighing approximately 4,000–9,900 lb, depending on the selected model. Professional weld-on installation is required. Auxiliary hydraulics are not required.

Not sure which size fits? Send CrewTough your excavator make, model, year, operating weight, bucket width, and coupler information. We’ll help confirm the right setup before you order.
