NM Attachments - Class 3 Hydraulic Stick-Pivot Thumb - Cushion Cylinder, Serrated Curved Tines - AR400 Tines [NM-3HSP-2T]

The NM Attachments Class 3 Hydraulic Stick-Pivot Thumb with Cushion Cylinder and Serrated Curved AR400 Tines is a two-tine hydraulic excavator thumb designed to improve material handling, gripping, and sorting performance. 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.

Built for Controlled Material Handling

The 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.

A 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.

Key Features

• Hydraulic stick-pivot excavator thumb design.
• Two serrated, curved tine ends for material handling.
• AR400 steel tine construction.
• Heavy-duty hydraulic cylinder.
• Cushion feature in the cylinder base end to reduce shock.
• Pivots from the main bucket pin.
• Provides constant grip while rotating the bucket.
• Designed for handling brush, debris, logs, rocks, and excavation materials.

Designed for Excavator Work

The 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.

The 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.

Compatibility and Tractor Requirements

This attachment is intended for excavators rated approximately 6,000–10,000 lb operating weight, equivalent to about 3–5 U.S. tons. Confirm that the excavator, bucket, and mounting arrangement are suitable for a hydraulic stick-pivot thumb before installation. The thumb mounts hydraulically and pivots from the main bucket pin.
