HYDRAULIC MAIN PIN THUMBS

Excavators

Hydraulic Main Pin Thumbs for Excavators deliver maximum control, productivity, and versatility across a wide range of applications. Designed and engineered by TAG Manufacturing, these heavy-duty hydraulic thumbs mount directly on the excavator’s main pin, providing precise material handling for demolition, land clearing, construction, and utility work.

Main pin thumbs offer superior strength and efficiency by aligning the thumb tine with the bucket or coupler pivot point. The tine mounts to an elongated main pin, while the hydraulic cylinder connects to an eyelet mounted on the stick. In some installations, welding may be required to add the eyelet. When available, TAG may attempt to utilize an OEM eyelet, though compatibility is not guaranteed.

Built for excavators and backhoes ranging from 2,500 lbs to 60,000+ lbs, TAG Hydraulic Main Pin Thumbs are engineered for demanding environments where reliability and performance matter most.
