HLA Attachments SFR70GRS66BO500 70-Inch Stone Fork with Retainer Tines and 66-Inch GRS66 Grapple is a regular-duty hydraulic attachment designed for handling stones, debris, and similar material with a compatible loader or skid steer. It combines a 70-inch stone fork, closely spaced retainer-style tines, and a 66-inch grapple in one versatile material-handling package. The grapple opens to 55 inches and is operated by two hydraulic cylinders, helping the operator secure bulky or irregular loads during pickup, transport, and placement. A BO500 universal skid-steer-style quick-attach mounting configuration provides compatibility with loaders and skid steers using this common carrier interface.
The SFR70GRS66BO500 combines the sorting and carrying characteristics of a stone fork with the added load control of a hydraulic grapple. Its 1-1/4-inch-diameter tines are spaced 2-1/2 inches apart, allowing loose material to pass between the tines while retaining larger stones and debris. Retainer-style tines support dependable material handling, while the grapple helps contain loads that could otherwise shift or roll during operation.
The included GRS66 skid-steer grapple has a 66-inch width and opens to a maximum of 55 inches. This grapple is specifically designed for skid steers with limited clearance for grapple arms. Two 2-1/2 x 8-inch hydraulic cylinders provide the grapple’s opening and closing action when connected to the loader’s auxiliary hydraulic system.
The 70-inch stone fork is rated for a 5,500 lb capacity. Its points are 5/8 inch thick and manufactured from 400 Brinell high-strength steel, providing durable contact surfaces for demanding stone and debris work. The stone-fork frame measures 23 inches high and 40 inches deep, creating a practical platform for gathering and supporting material.
With an approximate attachment weight of 1,075 lb, this configuration should be matched to a machine with suitable operating capacity, hydraulic capability, and attachment handling characteristics. The stone fork’s rated capacity describes the attachment; actual working capacity remains dependent on the host loader or skid steer and its operating limits.
This attachment is configured with the HLA BO500 universal skid-steer-style quick-attach mount. It is compatible with loaders and skid steers equipped with a corresponding universal skid-steer-style quick-attach carrier. Carrier type, machine lifting capacity, attachment weight, and hydraulic capability should all be considered when matching the stone fork and grapple to a host machine.
Loader auxiliary hydraulics are required to operate the grapple. The grapple is supplied with two 2-1/2 x 8-inch hydraulic cylinders. Hydraulic flow, operating pressure, hoses, and coupler requirements are not specified for this exact configuration, so the host machine’s hydraulic connection details should be confirmed before installation.
