The Kenco Excavator Thumb gives you total control for picking, placing, and demolition work. Built from AR 400 steel with case-hardened pins and precision line-bored bosses, these thumbs are engineered for strength and durability in the toughest land clearing and demolition conditions. Available in both mechanical and hydraulic models, they’re the essential tool to maximize your excavator’s versatility.
