How to safely cut blackberrry with a chainsaw

Here is the short version: a chainsaw is the wrong tool to start clearing a blackberry or gorse thicket with, and often the right tool to finish with. I learned that the first time I pushed a bar into a wall of blackberry behind the shed and watched a cane wrap itself around the clutch cover in about half a second. Flexible canes snag, whip, hide the bar tip and pull the saw off line — everything a chainsaw hates.

Getting this wrong is not a scratched-forearm problem. The tip of the guide bar contacting a hidden stem is the classic recipe for kickback, and old fence wire buried in a thicket can wreck a chain and throw debris at your face. The good news is the safe method is also the faster one once you see the job as two stages: strip the soft growth with the right tools first, then bring the chainsaw out for the solid wood.

This guide walks through why thickets and chainsaws don’t mix, which tools should do the first 80% of the work, how to clear in layers, the technique for the cuts a chainsaw genuinely should make, and how to stop the whole mess growing straight back.

⚡ Quick answer

Never drive a chainsaw directly into tangled blackberry or gorse. Remove the flexible growth with a brushcutter, hedge trimmer or loppers first, and use the chainsaw only on solid, visible, supported stems — in full chainsaw PPE, with a plan for the regrowth.

Do not drive a chainsaw into a tangled thicket. Flexible canes snag, whip, obscure the bar tip and pull the saw off line.

Remove the loose growth first. A brushcutter, hedge trimmer, loppers or a long-handled pruning saw expose the woody base.

Use the chainsaw only on solid, visible stems. Supported, clear of wire and stone, and thick enough that a pruning saw is no longer the smarter choice.

Wear the complete chainsaw safety system. Helmet, face and eye protection, hearing protection, chainsaw chaps, proper gloves and sturdy boots.

Plan for regrowth. Established blackberry and gorse come back from crowns, roots and stumps unless the clearing is followed up.

01 · THE RISKS

Why driving a chainsaw into a thicket goes wrong

A chainsaw is designed for solid, supported wood that stays put while the chain does the work. A blackberry or gorse thicket is the opposite: dozens of thin, springy, tangled stems under tension, hiding whatever fell into the patch over the last twenty years. Run a fast-moving chain through that and several things can go wrong at once:

Bar-tip contact. Hidden stems can touch the upper nose of the guide bar — the area most closely associated with chainsaw kickback.
Snagging. A cane can catch on the chain or wrap around the clutch cover and pull more vegetation — or your hands — toward the saw.
Whipping branches. Bent canes store energy like a spring and can release suddenly into your face, arms or hands.
Hidden metal and stone. Old fencing wire, nails, steel posts and rocks blunt or wreck a chain instantly and throw debris at speed.
Poor footing. Cut canes form loops and traps around your boots — a serious trip hazard while a saw is running.
Loss of visibility. Dense foliage hides the bar tip, the far side of the cut and anyone wandering into the work area.

⚠ The kickback problem, specifically

Kickback happens when the upper quarter of the bar nose contacts something the chain can’t cut through cleanly. In a thicket you cannot see the nose, so you cannot keep it clear. That is the whole case against blind cutting in one sentence. The guide to preventing chainsaw kickback covers the mechanics in detail.

The honest correction: a chainsaw does not “clear scrub”. It finishes a clearing job that other tools start. Once you accept that, the rest of this guide is just sequencing.

02 · FIRST TOOLS

The tools that should do the first 80% of the job

Five tools handle the soft, tangled stage better than a chainsaw ever will. Most jobs need two or three of them, not all five.

Brushcutter with a metal blade

Best for dense weeds, young gorse, broom and light woody growth

A brushcutter fitted with a manufacturer-approved metal brush or scrub blade sweeps through multiple small stems while keeping the cutting head well away from your body. It still throws stones, wire and vegetation at speed, so eye, face and hearing protection are non-negotiable. Never fit an improvised blade or one not approved for your machine’s guard, gearbox and handle configuration — and use the harness the manufacturer specifies.

Hedge trimmer

Best for reducing blackberry from the outside in

The long blade cuts several canes at once and creates access without putting your hands into the thorns. It shines on younger upper growth; thick brown crowns and mature gorse stems are beyond it and belong to loppers, a pruning saw or heavier gear.

Long-handled loppers

Best for isolated canes, broom stems and small gorse trunks

Control, leverage and reach — often the safest answer for a single awkward stem. Make a clean cut within the tool’s rated capacity and don’t twist or rock the handles sideways through the wood; overloading the pivot can make the tool slip suddenly.

Pruning saw

Best for exposed crowns and stems too big for loppers

A sharp pruning saw cuts surprisingly large woody stems and gives far better control close to soil, fencing and structures. It is slower than a chainsaw — and when visibility is poor, that slower action is exactly the advantage you want. Use a folding or curved pruning saw on exposed blackberry crowns and gorse, broom or hawthorn trunks.

Cordless reciprocating saw

Best for tight spots where a chainsaw is awkward or excessive

Fitted with a coarse pruning blade, the narrow blade reaches between stems and is easier to keep away from your body than a full chainsaw bar. Press the shoe firmly against the stem to control vibration, keep the blade out of the soil, and check for wire before every cut.

Tool	Best for	Watch out for
Brushcutter (metal blade)	Dense weeds, young gorse, broom, light woody growth	Thrown stones and wire; unapproved blades
Hedge trimmer	Young blackberry canes, outside-in reduction	Underpowered on thick brown crowns
Loppers	Isolated canes, small trunks up to rated capacity	Twisting the cut; overloading the pivot
Pruning saw	Exposed crowns, work near soil, fences and walls	Slower going — which is often the point
Reciprocating saw	Tight access between stems	Vibration; blade contact with soil and wire
Chainsaw	Solid, visible, supported stems only	Everything in section 01

03 · WALK THE SITE

Inspect the thicket before any tool starts

Walk around the entire patch before picking up a powered tool. Look from several angles — the far side of a thicket always hides something the near side doesn’t. You are looking for:

Old fences, wire, netting, steel stakes and nails.
Rocks, bottles, concrete, garden edging and buried rubbish.
Water pipes, hoses, irrigation lines and electrical cables.
Overhead power lines and low branches.
Drop-offs, drains, holes, slippery banks and unstable ground.
Wasp nests, bee activity, nesting birds and other wildlife — wasps love a New Zealand blackberry patch in late summer.
Roads, footpaths, neighbours, pets and anyone who may enter the area.

Do not begin until you have a clear work zone and a safe route out. Mapping the danger zones and escape routes is the same discipline as identifying chainsaw work area safety zones before felling — the thicket just hides more of the answers.

Keep people well clear. Brushcutters and chainsaws throw debris beyond the area you expect. Only one person works inside the immediate cutting zone. A helper stays outside the danger area and never holds, pulls or tensions vegetation while a chainsaw is cutting it — a cane under tension releases straight at whoever is holding it.

04 · THE METHOD

Clear in layers, from the edge inward

The method is simple and it never varies: work in shallow layers so you can always see what lies behind the section you are cutting.

Start at the accessible edge. Cut the higher, younger canes into manageable sections with the hedge trimmer, brushcutter or loppers. Do not push blindly into the middle.
Drag the debris clear as you go. Cut canes left at your feet form loops, rolling stems and thorny trip traps. Move them to a separate pile before cutting the next layer. Tough handling gloves are fine for this job — but ordinary gardening gloves are not a substitute for certified chainsaw gloves once the saw starts.
Expose the crown or trunks. With the loose growth gone, inspect the woody base and check again for wire, stone and soil packed around the stems.
Use hand tools wherever practical. Loppers or the pruning saw handle most crowns. Reserve the chainsaw for solid stems genuinely beyond them.

💡 The one rule that overrides everything else

If you cannot see it, you do not cut it. Every step in this method exists to turn hidden material into visible material before a chain touches it.

05 · CHAINSAW TECHNIQUE

When the chainsaw finally comes out

First, gear up properly. The complete chainsaw safety system means a forestry helmet with face and hearing protection, chainsaw chaps, proper chainsaw gloves and sturdy boots. Scrub work throws more debris at your face than clean firewood cutting, not less.

Then the cut itself:

Stand on stable ground with both feet planted. Hold the saw with both hands, left thumb wrapped underneath the front handle.
Keep your head and body out of the bar’s line. Cut below shoulder height and never reach into the thicket.
Cut with the lower edge of the bar where possible. That is the pulling-chain side — it draws the saw toward the wood and gives better control. The guide to making sharp and controlled chainsaw cuts explains the technique in detail.
Keep the nose of the bar visible at all times. Never plunge the tip into growth, and never make a blind cut.

⚠ If vegetation wraps around the saw

Release the throttle, engage the chain brake and switch the engine off. Pull the battery on a cordless saw or disconnect the spark-plug lead before your hands go anywhere near the chain or sprocket. Never pull tangled vegetation from a moving chain — that is how scrub-clearing injuries actually happen.

06 · CHAIN CONDITION

A sharp chain is a safety device

A blunt chain makes the operator push, twist and reposition the saw — exactly the reactions that are most dangerous around irregular stems and poor footing. Scrub work blunts chains fast, because sooner or later the chain kisses soil or stone no matter how careful you are.

Stop and check the chain the moment the saw produces fine dust instead of proper chips, smokes, pulls sideways or needs heavy pressure. The guide to sharpening a chainsaw correctly covers file size, angles and rhythm. And if the chain has cracked cutters, damaged drive links or loose rivets, sharpening won’t save it — these chainsaw-chain replacement signs will tell you when it’s done.

07 · KNOW WHEN TO STOP

When to put the saw down — or call someone in

Do not continue when you are tired, angry, rushing, losing the light or losing stable footing. Stop in high wind, heavy rain or any conditions that stop you seeing the bar tip and the material being cut. Scrub clearing is repetitive work and fatigue arrives quietly — the last hour of a long session is when the shortcuts start.

Call a professional when: the scrub covers a steep bank, hides major fencing, grows around power lines, surrounds a large tree under tension, or the job requires cutting above shoulder height. A contractor with a mulcher will clear in an afternoon what would take you a hard, thorny weekend — and they carry the insurance for the wire strikes.

08 · REGROWTH

Cutting is only half the job

The honest correction: cutting blackberry or gorse clears the site, but it does not kill the plant. Established blackberry regrows from crowns and root fragments; gorse reshoots from cut stumps and drops seed that stays viable in the soil for decades. Clear the patch and walk away, and in two seasons you are back where you started — with a better view of the problem.

Follow-up options, roughly in order of effort: treat freshly cut stumps with an appropriate herbicide gel within minutes of cutting (the cut surface seals fast), spray regrowth when it is young and soft — the guide to using glyphosate safely covers timing and technique — or keep the area mown or grazed so seedlings never re-establish. In New Zealand, both plants are listed pest plants in most regions, so your regional council’s pest-plant pages are worth a look for locally recommended control methods.

Frequently asked questions

Can you cut blackberry bushes with a chainsaw?

Not as a first step. Chainsaws are for solid wood, and blackberry canes are thin, flexible and tangled — they snag, whip and hide the bar tip. Strip the canes back with a brushcutter, hedge trimmer or loppers first, then use the chainsaw only on the exposed woody crown if it is genuinely too thick for a pruning saw.

What is the best tool for clearing gorse?

For young gorse, a brushcutter with an approved metal scrub blade. For mature trunks, loppers or a pruning saw once the surrounding growth is cleared, with a chainsaw reserved for the largest stems. Large infestations on rough ground are mulcher territory — hire a contractor.

Why is cutting brush with a chainsaw so dangerous?

Three reasons stack up: you cannot see the bar nose, so kickback risk climbs; flexible stems snag and pull the saw unpredictably; and thickets hide wire, stone and holes. Each is manageable alone — together they make blind thicket cutting one of the highest-risk things you can do with a saw.

What safety gear do I need to clear blackberry and gorse?

For the brushcutter and hand-tool stages: eye and face protection, hearing protection, tough gloves, long sleeves and sturdy boots. The moment the chainsaw starts, step up to the full system — forestry helmet with visor, hearing protection, chainsaw chaps, chainsaw gloves and boots.

Will blackberry grow back after cutting?

Yes. Blackberry regrows from crowns and roots, and gorse reshoots from stumps and seed. Treat cut stumps promptly, spray young regrowth, or keep the ground mown — otherwise cutting just prunes the plant into coming back thicker.

Should I just hire someone instead?

If the patch is large, on a steep bank, threaded with old fencing or anywhere near power lines — yes. A contractor with a mulching head does in hours what takes a weekend by hand, and the hire cost looks cheap next to one wire strike or one trip to the emergency department.

The bottom line

A chainsaw can absolutely help clear mature blackberry, gorse and similar scrub — but only after the flexible growth has been removed and the solid stems are fully exposed. Use the brushcutter, hedge trimmer, loppers and pruning saw for the first stages, and keep the chainsaw for the limited cuts it performs well: visible, supported wood at a safe height, with firm footing and a clear bar tip.

The safest clearing job is methodical. Inspect first, cut in layers, clear the ground as you go, wear the full PPE, plan the regrowth control before you start — and stop the moment the material begins to control the saw instead of the saw controlling the cut.
