Letsdig18 Stick Pivot Hydraulic Thumb

The Custom Edition LETSDIG18 - Hydraulic Stick Pivot Thumb provides great functionality to your excavator and backhoe. Stick Pivot means the thumb rotates on the same pivot point as the original bucket pin, not a secondary weld-on pivot point. The hydraulic cylinder is also directly connected to the thumb, covering 65-75% bucket rotation. Since both the thumb and the bucket rotate on the same axis, the thumb tip and bucket teeth maintain constant grip on the load when rotating. Unlike thumbs that use a secondary weld-on pivot point, the LETSDIG18 Custom Edition Stick Pivot eliminates scraping and slippage and reduces risk of release during rotation. The LETSDIG18 Hydraulic Stick Pivot Thumb also exclusively features Hardox® tines positioned between each tooth.

Product Features

Bucket Pin Rotation Point

The hydraulic cylinder is also directly connected to the thumb, covering 65-75% bucket rotation. Since both the thumb and the bucket rotate on the same axis, the thumb tip and bucket teeth maintain constant grip on the load when rotating.

Spherical Bushings

The hydraulic cylinder’s seals stay intact by allowing the thumb to naturally flex when handling awkward material without adding torsional stress to the seals.

Cushioning Cylinder

By restricting the flow of hydraulic oil at the end of the cylinder stroke, AMI thumbs retract smoothly without a hard stop. This reduces the wear and tear on the excavator and prevents machine shake, making it more comfortable for the operator.

Hardox® - Strenx™

The tines are made from Hardox® 450 Wear Plate. This is a special steel that is significantly harder than simple AR400. Hardox® wears evenly over time compared to AR400 which is only heat treated on the outside. In the middle, the steel is still soft and will wear down faster and inconsistently. Made for strength without extra weight, Strenx® is a structural steel which reduces the weight.
