Description
HLA Attachments SFR77GR66BO500 Stone Fork with Retainer Tines and GR66 Grapple combines a 77-inch regular-duty stone fork with a 66-inch hydraulic utility grapple for efficient stone and debris handling. Designed for loaders equipped with a compatible skid-steer-style quick-attach interface, this attachment allows material to be gathered, retained, and moved using one integrated package. Its closely spaced retainer-style tines help separate stones and debris from finer material, while the grapple opens up to 70 inches to accommodate bulky or irregular loads.
Stone and Debris Handling
The regular-duty stone fork has a 77-inch nominal width, a 23-inch frame height, and a 40-inch depth. Its tines are arranged with 2-1/2-inch spacing, allowing loose soil and smaller material to pass between them while retaining larger stones and debris. The fork uses a 1-1/4-inch tine shaft and has 5/8-inch-thick tine points manufactured from 400 Brinell high-strength steel.
The underlying regular-duty fork is rated for a 5,500 lb capacity. This construction makes the attachment suitable for stone and debris handling applications where both material separation and secure load control are important.
Integrated GR66 Hydraulic Grapple
A 66-inch GR66 regular utility grapple provides hydraulic load control over the stone fork. With an opening of up to 70 inches, the grapple can close around irregular material and help retain stones or debris while the loader is travelling or repositioning a load.
The grapple is operated by two 2-1/2-inch by 8-inch hydraulic cylinders. A loader auxiliary hydraulic circuit is required for operation. HLA does not publish a hydraulic flow or pressure requirement for this model, so the loader and hydraulic connection should be checked for suitability before installation.
