The sequence you run attachments in on a land clearing job matters more than most operators think. Mulch first, then grapple, then grade. Here's why that order exists, what breaks down if you change it, and how to adapt for different site conditions.
Land clearing looks like brute-force work. Push stuff over, pile it up, burn it or haul it — done. That's one way to do it. It's also inefficient, hard on the machine, and produces a site that still needs substantial prep work before you can grade or plant.
The operators who move the most ground the fastest tend to be methodical about sequence. They know which attachment handles each type of material, and they don't try to make one attachment do a job it wasn't designed for. What follows is the sequencing logic — what goes first, why, and what happens on the ground when you get it right.
The problem with clearing out of order isn't that the job is impossible. It's that you create obstacles for yourself. Try to grade a site with stumps still in the ground — the bucket rides over them, you get an uneven finish, and the stumps start showing six months later. Try to grapple a site where 4-inch-diameter brush is still standing in thick mats — the grapple grabs some of it but tangles constantly and barely moves brush that a mulcher would handle in seconds.
Every attachment has a material type it excels at. The sequence is built around feeding each attachment the right material at the right time:
If you mulch first, the mulcher handles all the standing brush efficiently with nothing in its way. Then the grapple is working with manageable debris — logs and stumps, not a tangled standing mat. Then the stump grinder hits a clean surface where stumps are clearly visible, not buried in debris. Then the bucket grades a surface that's already close to flat. Each phase leaves the site in better condition for the next.
The mulcher is phase one because it reduces the volume of everything in the clearing area dramatically. A 2-acre lot with dense alder and poplar — common scrub on old fields in Ontario, Quebec, and Atlantic Canada — might be 80% brush by volume. Run a drum mulcher through it and that 2 acres becomes manageable debris on the ground instead of an impenetrable vertical thicket the grapple can barely enter.
High-flow mulchers (25–45 GPM, 2,500 PSI) like the Fecon FTX-148 or FAE DML/SSL work trees up to 8–10 inches in diameter. Standard-flow units (18–22 GPM) handle material up to about 4–5 inches. Know which your machine supports before spec'ing the attachment.
The mulcher produces chips in place — there's no hauling, no burning, no pile. That's the primary operational advantage. On jobs where material disposal is a problem (can't burn, no truck access for hauling), the mulcher solves it entirely. The mulch layer it leaves behind isn't permanent — it compresses and rots within a season or two.
After the mulcher has processed standing brush, the remaining debris is piles of mulch, logs that were too large for the mulcher, and any material you deliberately skipped in phase one. The grapple comes on now — and it works fast because it's operating on open ground with visible material.
A root grapple with a 72-inch to 84-inch opening grabs logs, brush piles, and tree stumps that have been loosened or undercut. The Virnig V60RG and the Caterpillar Work Tool grapples in that size class handle serious load weights — the Virnig is rated for skid steers up to 3,500 lb ROC. For contractor-level land clearing in Canada, the ability to grab a 24-inch diameter log and load it to a truck or pile is what determines job pace.
The grapple's job in phase two is twofold:
Stumps left in place create two problems: they're invisible under a thin topsoil cap and will heave equipment, and any seeding or grading work over them becomes unstable as they rot. On residential clearing jobs where the finished surface will be lawn, foundation, or road base, stumps need to go below grade.
Skid steer stump grinder attachments work by feeding a high-speed carbide-tipped grinding wheel into the stump crown and grinding it down 6–12 inches below grade. The resulting material is coarse wood chips mixed with soil — it can be raked into the void or used as mulch. What's left is a slightly depressed area with a mix of wood and soil that will settle as it decomposes.
Stump grinder attachments for skid steers include units from Bobcat (SG60, SG70), Fecon, and manufacturers like Eterra and TMG. The Bobcat SG70 with its 7.5-inch cutting wheel handles stumps up to 36 inches in diameter — large enough for most residential clearing jobs. Bigger stumps on forestry sites need a dedicated tracked stump grinder, not a skid steer attachment.
Phase three comes after the grapple specifically because the grapple has already cleared the debris from around the stumps. If you try to grind stumps with debris piled against them, the grinder can't get at the stump crown properly and you end up grinding material that isn't stump. Clear the area with the grapple first. Then grind clean stumps efficiently.
By phase four, the site should be clear of standing material, large debris, and stump crowns. What's left is rough ground: ruts from machine passes, stump grindings, mulch mat from phase one, and the natural surface irregularity of land that just had roots pulled out of it.
The GP bucket handles the bulk of this. On smaller sites or tight tolerances, a box blade or land plane attachment produces a more consistent finish grade. The box blade is particularly useful for sites with stockpiled topsoil to spread — it can spread and grade in the same pass.
Key things to address in phase four:
Don't try to do finish grading until the site is genuinely clear. This sounds obvious but isn't — if there's still wood debris just under the surface (buried by bucket work from earlier passes), the finish grade will settle and produce bumps as that material decompresses. Take a slow final pass with the grapple before committing to finish grade.
The mulch-grapple-grind-grade sequence works for dense brush with significant tree cover. Adjust it for different conditions:
| Site Condition | Adjustment | Why |
|---|---|---|
| Mature timber (>12" diameter trees) present | Fell trees manually (chainsaw) before mulching. Buck logs before grappling. | Mulcher can't handle trunk diameter. Fell first, then process. |
| Rocky terrain — Nova Scotia, Shield country, Laurentians | Use grapple before mulcher to clear large surface rocks. Set mulcher depth to avoid rock contact. | Rock contact damages mulcher cutting teeth fast. Remove obstacles first. |
| Material has commercial value (firewood, timber) | Grapple large wood before mulching to separate it for sale or use. | Mulching destroys commercial value. Grapple valuable material first. |
| Finished surface will be seeded pasture only | Skip stump grinding. Disc mulch the stumps down to grade level and leave root system to decay. | Grinding is expensive for agricultural use where stumps don't affect operations. |
| Wetland edge or near watercourse | Check provincial regulations before operating. BC, Ontario, and Quebec all have buffer zone restrictions near waterways. | Ground disturbance within riparian buffers may require authorization or is prohibited. |
| Thin organic site — one pass to bare mineral soil | Skip mulcher and go directly to grapple and bucket. The mulcher creates unnecessary material to clean up. | Thin brush clears faster by direct removal than by mulching and then clearing mulch. |
Not every clearing job needs the full four-phase sequence. Here's when you can simplify:
On a lot with no standing brush — wind-down timber, old brush piles, surface debris from construction — a grapple alone handles the job. No mulcher needed. Load the material, haul or pile, grade with a bucket. This is probably 40% of residential clearing jobs in Canada: lots that look messy but aren't actually heavily vegetated.
On a pipeline right-of-way or utility corridor where you're maintaining cleared width and the growth is all brush under 6 inches — the mulcher alone is the right call. Cut and chip in place, no hauling. The chips decompose over the season. Fast, efficient, no secondary passes needed.
Dense brush with shallow roots (aspen stands, alder thickets, Manitoba maple scrub) can often be handled with mulcher and bucket only. The mulcher grinds the standing brush. The bucket pushes the mulch into a leveling pass across the site. No stumps to grind because the mulcher ground them. No hauling because the mulch stays in place. This is the fastest clearing sequence for young-growth scrub sites.
