Clearing sight lines, driving stakes, cutting access, and prepping undeveloped parcels for survey crews — what attachments actually help, and what's overkill for the job.
Survey work and preliminary site assessment occupy an odd space in the equipment world. The jobs are often too heavy for hand tools but too delicate for full excavators. A Bobcat or CAT skid steer with the right attachment is frequently the sweet spot — compact enough to work in tight bush, capable enough to actually move material, and fast enough to keep a survey crew on schedule.
This is especially true in Canada, where a huge proportion of land being assessed for development, resource extraction, or infrastructure sits under significant vegetation. A parcel in Northern Ontario or BC's Interior that hasn't been accessed in decades will have second-growth bush, blow-down, and scrub that renders a GPS rod useless without clearing work first.
The fundamental challenge in survey work is line-of-sight. Total stations, levels, and traditional optical instruments require clear sightlines between points. Even GPS-based survey workflows — which have reduced but not eliminated this need — require clearing for benchmark placement, monument access, and ground truthing in heavy canopy.
Secondary to sight lines: access. Survey crews need to physically reach corner monuments, benchmarks, and traverse points. In undeveloped land, that often means cutting a path through brush, crossing drainage features, or climbing slopes where no trail exists. Sending a survey party in on foot with chainsaws is slow and expensive. Sending a skid steer ahead to cut access changes the math entirely.
Third consideration: staking and marking. Post-hole augers and post drivers on skid steers can set survey stakes, boundary markers, and grade stakes far faster than hand-driving. On hard prairie soils or rocky Laurentian Shield ground, trying to drive a 2" wood stake by hand is genuinely brutal. A hydraulic post driver on a skid steer does it in seconds.
For opening up sightlines through secondary growth, a brush cutter or forestry mulcher is the core tool. The key distinction: brush cutters are faster and cheaper, mulchers are cleaner and leave less debris.
For survey work specifically, a mulcher often wins. Brush cutter debris — scattered branches, clippings — can physically obstruct the sight line you just created. Mulch stays flat and low. A 60" or 72" forestry mulcher running through a line of 4–6" diameter saplings leaves the corridor walkable and visually clear within a single pass.
On BC coastal projects where vegetation is dense and wet, you're looking at drum mulchers with carbide teeth — they handle wet wood and greenery that would bog down a flail-style unit. In the drier Alberta foothills or prairie margins, flail-style brush cutters are adequate and considerably cheaper to run.
Sight-line corridors for survey work are typically narrow — 1.5 to 3 metres is usually enough. A 60" attachment gives you reasonable clearance while remaining nimble. Go wider and you risk disturbing more ground than the survey actually requires, which can create problems on environmentally sensitive parcels or where regulatory clearances govern disturbance limits.
Survey monuments — the physical markers that demarcate property boundaries, benchmarks, and traverse points — often need to be set in difficult ground. Iron pins driven into prairie soil. PK nails in asphalt. Rebar in rocky ground. But also: wooden witness posts, range poles with concrete, and boundary posts that need to withstand years of freeze-thaw cycles.
For setting monument protection posts and boundary markers, a skid steer auger attachment with an appropriate bit is the right tool. A 4" or 6" bit sinks a post hole in compacted soil in under a minute. In rocky or frozen ground, you'll want an auger drive unit rated for high-torque work — the cheaper gear-motor drives bog down badly in Canadian Shield terrain.
Bit selection matters here. On gravelly glacial till common across much of Western Canada, a Pengo or Digga rock auger bit with carbide flighting will stay sharp considerably longer than a standard dirt bit. In established clay soils in the Great Lakes basin, standard flighting is fine but pilot tips help with centering on tight placements.
One practical note: survey monument placement often requires precision positioning. Skid steer augers don't offer the inch-perfect placement of a hand auger, but they're close enough for witness posts and protective monuments. The monument itself (iron rod, brass cap) gets placed by hand; the skid steer just sinks the surrounding hole.
Post drivers on skid steers are underused in survey contexts, but they're extremely effective for temporary staking — grade stakes for preliminary earthworks design, boundary witness posts, and flagging lath in quantity. A hydraulic post driver handles 1.5" x 1.5" wooden lath stakes in a single stroke, even in compacted prairie soil that would bend a hand-driven stake.
Where this matters most: large parcel assessments. If a survey crew is working a 200-acre rural parcel for subdivision design, they might need to set 60–80 temporary stakes over the course of two days. Do that by hand in August in Saskatchewan — baked hard, +35°C — and you're burning out your field crew. The skid steer does it in a quarter of the time.
Establishing a temporary access route to a remote survey area — or creating a stable platform for survey equipment in soft terrain — is another skid steer task that survey contractors often overlook. A box blade or land plane can rough-cut a two-track track into a field or bush parcel in an hour. Not a finished road — just passable for a pickup truck and equipment trailer.
Benchmark placement sometimes requires a level pad. If you're installing a semi-permanent benchmark on soft or uneven ground, a few passes with a box blade to level a 3 x 3 metre area saves the crew from working off a shaky setup. It sounds like a minor thing. It's not, when you're running a digital level.
Old parcels — especially in Ontario, Quebec, and BC — often have decades of blow-down, deadfall, and slash. You can't mulch it all (too large), and you can't just push it around without creating new sight obstructions. A root grapple lets the operator selectively pick up and move debris to the parcel edge, keeping the survey corridor clean without creating debris piles mid-site.
This is precise work. The grapple operator needs to be deliberate — don't bury a survey corner monument under a slash pile, and don't disturb flagged corners. Good operators can work within a metre or two of a staked location without touching it. That said, survey crew and machine operator should always coordinate positions clearly before clearing starts near known monument locations.
A significant chunk of Canadian survey work happens in late fall and early spring — outside the mud season window when machines can move across soft ground without churning it up. That means working in frozen or near-frozen conditions.
Frozen ground changes post hole work significantly. Standard dirt auger bits will bounce off frost-hardened clay. A rock bit handles it, but you'll want your auger drive unit running at full hydraulic flow to maintain torque through the frozen layer. Most frost penetration in Southern Canada reaches 0.6–1.2 metres in a typical winter; the deeper you need to go, the more it matters.
Brush cutting in frozen conditions is actually easier in some ways — frozen stems cut cleaner than green wood, and compacted frozen ground means the machine sinks less. Rubber tracks help with traction on icy slopes. The bigger hazard is hydraulic performance in cold — see our winterizing guide for pre-operation warm-up procedures that protect hydraulic seals below -20°C.
Some attachments look useful for survey support but rarely justify the hassle. Trenchers, for instance — useful if you're cutting drainage or burying conduit, but not for survey prep. Cold planers, rock saws — these are infrastructure tools, not site assessment tools.
Vibratory plate compactors have no real place in survey work unless you're compacting a temporary aggregate access pad. Skip anything that disturbs ground beyond what the sight-line clearing actually requires — especially on parcels with environmental covenants, riparian setbacks, or cultural heritage designations, all of which are common in BC, Quebec, and parts of Ontario under provincial heritage legislation.
Survey support doesn't require a full-size skid steer. In fact, a compact track loader — a Bobcat T595 or Cat 299D — is often better than a wheeled machine on undeveloped parcels with soft or uneven terrain. Track undercarriages distribute weight more evenly and leave a shallower footprint, which matters when you're trying to preserve ground conditions for geotech sampling or environmental assessment.
For pure brush cutting and stake-driving, a mid-size wheeled skid steer (65–85 hp range) is adequate and cheaper to move. If the parcel has significant elevation change or soft wet areas, track loader every time.
Hydraulic flow requirements are modest for this application: augers need 15–25 GPM, brush cutters 20–35 GPM depending on width. Standard-flow machines handle both. High-flow is overkill unless you're running a wide forestry mulcher (60"+) on dense material.
Coordination note: Always establish a clear communication protocol between the survey crew and skid steer operator before clearing begins. Monument locations should be physically flagged with tall lath or brightly coloured stakes before the machine enters the site — not marked on a paper plan that the operator has to reference mid-task. Disturbing a benchmark or destroying a corner monument creates survey liability that nobody wants.
For a survey contractor supporting land assessment work in Canada, the attachment priority list looks like this:
None of these are exotic. Most rental yards in any Canadian city carry all of them. If the survey is occasional work, renting makes more sense than owning — a 72-hour brush cutter rental covers most site preparation scenarios at a fraction of the purchase cost.
