Stiff-Arm Thumb

ACS Weld-On Thumbs are designed to be universal — one thumb will install on just about any model backhoe. This removes the cost of customization from of the manufacturing process and provides a quality built thumb at significant savings.

Rigid-link connection between the thumb body and stick. Manually adjustable to three different working angles with a fourth position for stowing out of the way when not in use.  No hydraulics are required for this thumb.

Upgrade to a Direct Connect Hydraulic Thumb. Field Upgrade Kit to add a hydraulic actuation to your thumb is available.

ACS Thumbs are available with either serrated or smooth teeth. Thumb teeth crafted from tough, long lasting HX400 material.
