Its stick-pivot design mounts by pivoting from the main bucket pin, helping maintain a constant grip as the bucket rotates. Built for excavators rated approximately 6,000–10,000 lb operating weight, this thumb is suited to handling brush, debris, logs, rocks, and general excavation materials.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt for Controlled Material Handling\u003c\/h2\u003e\n\u003cp\u003eThe NM-3HSP-2T combines a heavy-duty hydraulic cylinder with two curved, serrated tine ends. The curved tine profile helps engage material, while the serrated ends provide additional contact for handling loads during excavation and cleanup work. The hydraulic stick-pivot arrangement allows the thumb to work with the excavator bucket rather than functioning as a fixed attachment, supporting controlled gripping as the bucket moves.\u003c\/p\u003e\n\n\u003cp\u003eA cushion feature in the base end of the hydraulic cylinder helps reduce shock during operation. This design supports smoother thumb movement when the attachment is cycled and when material is engaged or released.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eHydraulic stick-pivot excavator thumb design.\u003c\/li\u003e\n  \u003cli\u003eTwo serrated, curved tine ends for material handling.\u003c\/li\u003e\n  \u003cli\u003eAR400 steel tine construction.\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty hydraulic cylinder.\u003c\/li\u003e\n  \u003cli\u003eCushion feature in the cylinder base end to reduce shock.\u003c\/li\u003e\n  \u003cli\u003ePivots from the main bucket pin.\u003c\/li\u003e\n  \u003cli\u003eProvides constant grip while rotating the bucket.\u003c\/li\u003e\n  \u003cli\u003eDesigned for handling brush, debris, logs, rocks, and excavation materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eDesigned for Excavator Work\u003c\/h2\u003e\n\u003cp\u003eThe stick-pivot mounting principle allows the thumb to pivot from the main bucket pin while working with the bucket. This makes the attachment suitable for tasks that require the operator to hold, reposition, gather, or sort material. The two-tine configuration provides a practical gripping arrangement for common excavator handling applications, including clearing brush, moving debris, handling logs, and managing rocks around excavation sites.\u003c\/p\u003e\n\n\u003cp\u003eThe AR400 steel tines are intended for demanding attachment use, while the serrated and curved geometry helps the thumb maintain contact with material. The hydraulic cylinder supplies the operating movement needed to bring the thumb into position against the bucket.\u003c\/p\u003e\n\n\u003ch2\u003eCompatibility and Tractor Requirements\u003c\/h2\u003e\n\u003cp\u003eThis attachment is intended for excavators rated approximately \u003cstrong\u003e6,000–10,000 lb operating weight\u003c\/strong\u003e, equivalent to about \u003cstrong\u003e3–5 U.S. tons\u003c\/strong\u003e.
