Introduction

A grapple built for getting things done.

The Rock Haul HD rock grapple bucket is engineered to sift soil and pick rocks and debris from the ground, with the added feature of independent grapples to secure a variety of materials. Extra long tines allow you to carry larger loads. Gusseted tines make this skeleton grapple bucket versatile for rooting and back dragging as well. Need a lighter option or a 60 inch width? See the standard Rock Haul.

Why Steel Strength Matters

Built With High-Strength Steel
Not Marketing Terms.

Not all steel ratings are presented the same way.

Some manufacturers advertise maximum breaking strength, while others reference minimum yield strength. At Quick Attach, we focus on real-world durability and structural performance — not inflated numbers.

Our steel specifications are based on minimum strength ratings to give operators a clearer understanding of what the grapple is built to handle.

How the Rock Haul HD Works, and Which One You Need

What a Rock Grapple Bucket Does

A rock grapple bucket, also called a skeleton bucket or a rock bucket with grapple, is built from spaced steel tines instead of a solid floor. When you drive into a pile of soil and rock, the dirt falls straight through the gaps between the tines and stays on the ground where it belongs, so what is left in the bucket is the rock, root, brush or demolition debris you actually wanted to move. A standard bucket lifts everything and you end up hauling away good topsoil along with the stone. The Rock Haul HD separates as it loads, using 1/2 inch tines spaced 2.625 inches apart, tight enough to hold back small stone while letting soil sift away, so a single pass does the work of scooping, sorting and carrying.

What the Grapple Adds

A plain skeleton bucket holds material only as long as the bucket stays tipped back. The moment you have an awkward load, a long root ball or a boulder that sits proud of the rim, it rolls out. The two independent grapples on the Rock Haul HD clamp down over the top of the load with a 36 inch opening, and because they move independently they close on to uneven shapes rather than teetering on the highest point. That is the difference between a rock bucket and a rock grapple bucket, and it is why operators clearing land or stripping a demolition site choose the grapple version.

Where Operators Use It

Land clearing and site prep, where the tines sift soil back out while the grapples hold roots, stumps and brush a solid bucket cannot keep hold of. Rock and stone picking on fields and pastures, working a paddock without stripping the topsoil underneath. Demolition and jobsite cleanup, where broken concrete, block and rebar offcuts load and travel securely under the independent grapples. Landscaping and driveway restoration, reclaiming gravel or sorting stone out of imported fill. Loading and sorting aggregate around a yard without carrying dirt with it. Storm and brush cleanup, where the grapples clamp a full load of downed limbs and the tines shed the mud instead of hauling it to the burn pile.

Rock Haul, Rock Haul HD or Rock Scoop: Which One You Need

Quick Attach builds three attachments for sifting and moving rock, and the right one depends on how hard you work it and whether you need the grapple at all. The Rock Scoop skid steer rock bucket has no grapples, built for sifting and loading stone where you never need to clamp a load. The standard Rock Haul rock bucket grapple adds independent grapples with a wider 38.75 inch opening and a 60 inch width option, the everyday choice for general property work and routine rock handling. The Rock Haul HD narrows the opening to 36 inches and drops the 60 inch width, and in exchange it is the version built for daily heavy use: demolition debris, land clearing and jobs where the attachment is loaded and levered every working day. If you only sift and load stone with no clamping needed, the Rock Scoop is the simpler tool. If you want the grapple but are not running eight hours a day on demolition debris, the standard Rock Haul fits better. Or browse all skid steer grapples to compare the full range.

Rock Haul HD Questions

What is the difference between a rock bucket and a rock grapple bucket?

A rock bucket, sometimes called a skeleton bucket, is built from spaced steel tines instead of a solid floor, so soil falls through the gaps while rock and debris stay in the bucket. A rock grapple bucket is the same tool with hydraulic grapple arms added on top. The grapples clamp down over the load, which lets you carry material that sits above the rim of the bucket, such as boulders, root balls, long timber and brush. Without the grapple, anything that will not sit flat inside the bucket rolls out when the machine moves. The Rock Haul HD uses two independent grapples with a 36 inch opening, and because they move separately they close on to uneven loads instead of balancing on the highest point.

What size rock grapple bucket do I need for my skid steer?

Match the width to your machine, not to the job. As a general rule the attachment should be as wide as or slightly wider than the machine's tyre or track width, so you are not leaving an untouched strip behind you and so the load stays centred. Beyond width, the deciding factor is your loader's rated operating capacity, because a wide attachment full of wet stone gets heavy fast and a machine that is over its limit is both slower and less safe. The Rock Haul HD comes in 72 inch and 84 inch widths. If you are unsure which suits your loader, send us your make and model when you request a quote and we will confirm it against your lift capacity.

Do I need a third function hydraulic kit to run this grapple?

The grapple arms are hydraulic, so the attachment needs a hydraulic circuit to open and close them that is separate from the circuit driving the loader arms and the tilt. On most skid steers that means auxiliary hydraulics with a third function valve, sometimes called a diverter kit. Many newer machines have this fitted from the factory. Older machines and some smaller models do not, and the kit has to be added. Check your machine's spec sheet for a third function or auxiliary hydraulic option before ordering, and if you are not sure, tell us your make and model when you request a quote and we will check it with you.

What is tine spacing and why does it matter?

Tine spacing is the gap between each steel bar across the floor of the bucket, and it decides what falls through and what stays. The Rock Haul HD uses 2.625 inch spacing, which is tight enough to keep smaller stone and gravel in the bucket while still letting soil sift away. Tighter spacing is what you want when picking stone out of a field, cleaning up a finished grade or reclaiming aggregate. Wider spacing moves bulk material faster on rough land clearing but lets small stone escape with the soil. Spacing also decides how much dirt you end up hauling: too wide and you lose the stone you were collecting, too tight and you carry away the topsoil you were trying to keep.

What steel is the Rock Haul HD made from and what does Grade 50 mean?

The Rock Haul HD is built from Grade 50 steel with 1/2 inch gusseted tines. Grade 50 means a minimum yield strength of 50,000 PSI and a tensile strength of 65,000 PSI, with a hardness of around 135 BHN. Yield strength is the point at which steel bends permanently and tensile strength is the point at which it breaks, so yield is the number that matters most on an attachment that gets loaded and levered every day. For comparison, common A36 mild steel yields at 36,000 PSI. We quote minimum yield ratings rather than maximum breaking strength, because a maximum figure tells you what it takes to destroy the attachment and a minimum yield figure tells you what it will actually hold up to on a jobsite.

Can I use a rock grapple bucket for back dragging and grading?

Yes, and it is one of the reasons operators choose this attachment over a plain bucket. The gusseted tines on the Rock Haul HD are reinforced at the root, which is the point that takes the load when you drag backwards, so the attachment levels ground on the return pass instead of forcing you to swap to a different tool. It will not replace a dedicated land plane or a grader blade for a true finish grade, but for rough levelling as part of a clearing or site prep job it saves an attachment change every pass.

What jobs is a heavy duty rock grapple bucket best for?

Land clearing and site preparation, picking stone out of fields and pastures, demolition and jobsite cleanup, gravel and driveway restoration, sorting and loading aggregate, and storm and brush cleanup. The common thread is any job where you need to separate the material you want from the soil you do not, and then carry a load that will not sit flat in a standard bucket. If your work is mostly moving loose material with no sorting involved, a standard or low profile material bucket will be faster and cheaper.

Where is the Rock Haul HD made and what warranty comes with it?

It is manufactured in the United States and carries a two year warranty. Quick Attach builds its attachments in Minnesota rather than importing them, which means parts availability and support come from the same place the attachment was welded.
