Brush pile cleanup and logging slash handling are where a root grapple earns its keep. The work looks simple — grab the pile, drag it somewhere, repeat. In practice, the difference between productive clearing and a half-day wrestling match with tangles and tip scares comes down to pile planning, loading sequence, and grapple selection. This guide covers the technique side in depth.
For general grapple operation and approach angles, see our how to use a skid steer grapple guide. This article focuses specifically on brush pile and slash work — the forestry clearing side of grapple use.
Brush and slash have three characteristics that make them challenging compared to logs, rocks, or palletized material:
They tangle. Brush branches interlock. A branch from one pile is often physically connected to material 15 feet away. You grab a section and the whole pile shifts, or you lift and an attached piece from the adjacent pile yanks back on you.
They're unpredictable in weight. A cubic yard of fresh green brush can weigh 200–400 lbs. The same volume of dry slash from a year-old cut might weigh 80–120 lbs. You can't judge a load visually. In green, heavy material it's easy to grab more than you think.
They're lowest-density-per-trip material. Brush compresses somewhat but not dramatically. A grapple full of light brush may be at its volume limit while barely touching ROC. Good news from a safety standpoint; frustrating from a productivity standpoint. You'll make more trips than you expect.
Not every grapple is suited for serious brush clearing. The main choices:
This is the standard tool for this work. The open tine frame lets you grab loose brush without trapping a vacuum — a solid-bottom grapple creates resistance when you're trying to pick up piled material at ground level. Root grapple tine spacing (typically 6–8 inches between tines on most Canadian-market models) is right for grabbing branch material while letting dirt fall through. A 72" dual-cylinder root grapple is the configuration most operators running regular land clearing work prefer. The width grabs a meaningful pile in one pass; the dual cylinders close evenly on asymmetric loads.
A brush grapple has a bucket-shaped lower jaw rather than open tines. It's better for smaller debris, leaves, and finer material that would fall through a root grapple. For slash clearing where the material includes a lot of small-diameter branches and needle debris, a brush grapple recovers more material per pass. Downside: it's heavier and costs more ROC budget. In clean slash with larger branch diameters, a root grapple is faster.
These are general-purpose attachments that function as both a bucket and a grapple. Fine for mixed jobs but not ideal as a primary brush-clearing tool. The solid floor makes it harder to scoop into a brush pile at ground level, and you lose material over the sides on tangled loads.
Random grabbing is the slow approach. Before the first pass:
Where is the material going? If you're burning, locate the burn area first. If you're chipping or loading for haul-out, set that location before you move anything. Every piece of brush you move is a trip; the shorter those trips the faster the job. A destination 300 feet away doubles your cycle time versus 150 feet.
When you're building a burn pile or consolidation pile, pile orientation matters. Build a burn pile with the most combustible material (fine branches, leaves, needle debris) toward the inside and the larger diameter material on the outside. This makes for better combustion and reduces flare-up risk from wind getting into the pile core. Use the grapple to orient loads as you drop them — not just dump randomly.
On larger forestry operations in BC and Alberta, slash is often windrowed rather than piled. A windrow is a linear accumulation along one side of the clearing area. Windrowing with a grapple is efficient — you're always dragging to one side rather than navigating to a specific pile location. Windrows are easier to burn in one controlled pass. They also minimize machine travel. For any clearing job over an acre, windrow first, consolidate later.
Approaching a brush pile from uphill means your machine is on the high side and the load stays closer to the machine's centre of gravity. Approaching uphill into a pile that needs to be carried uphill is the scenario where tip-overs happen. If the pile is below you, carry it down — easier on the machine and faster overall.
Trying to drive into the middle of a large brush pile means the machine is surrounded by material. Start at the nearest face of the pile, grab the outer section, deposit it, come back and work inward. This keeps you maneuverable and prevents the machine from getting bogged in the pile.
Open the grapple fully. Lower it to ground level. Drive slowly into the pile — let the grapple open jaw push into the material and gather it. Close when you feel solid resistance. This forward compression before closing captures more material per grab than stopping and closing from a stationary position. The difference is roughly 30–40% more material per pass in loose brush.
This is when loads fall apart. Raise slowly from ground to knee-height, pause briefly to let the load settle into the grapple. Then raise to travel height. A smooth raise outperforms a quick lift every time for keeping loads intact.
Don't raise to full height to travel unless you need to clear an obstacle. Low travel centre of gravity, better visibility, and if the grapple opens accidentally (a real risk on older machines with worn hydraulic solenoids) the load drops 2 feet instead of 8.
Lower the load over the destination pile before releasing. Don't open at height and let material free-fall — that scatters material and requires extra cleanup passes. Lower to within 2–3 feet of the pile surface, release, back out. Efficient cycle.
Post-logging slash cleanup — handling the tops, branches, and small-diameter material left after timber harvest — is a specific variant of brush work with some different considerations.
Slash is typically drier than fresh brush (unless you're cleaning up a recent cut), and includes more mixed diameters. The biggest challenge is dealing with the "jackstraw" tangle — slash that's fallen in every direction and interlocked. Working jackstraw with a grapple is slow if you fight it. The technique that experienced land clearing operators use:
In BC and Alberta during fire season (typically June through September), operating a skid steer in dry slash generates real fire risk. The steel cutting edges, hydraulic fittings hitting rocks, and any mechanical friction all generate sparks.
Under BC's Industrial Health and Safety Regulation and Alberta's forestry fire regulations, operators in high-risk areas may be required to have spark arrestors, fire extinguishers on the machine, and designated fire watch during and after operations. This varies by district and fire risk rating. Don't assume you know what the current rules are — check with local forestry authorities or the JobSafe BC wildfire resources before running equipment in dry slash during peak summer.
Practically: work in the morning when relative humidity is higher. Stop by early afternoon on high fire-risk days. Have a 9-litre water extinguisher on the machine. These aren't just regulatory requirements — they're common sense in a province that had 2,200+ fires in a single season.
