Gorse and scrub chew through underpowered mowers fast. This ranking sorts the flail mowers built for woody stems and rough ground from the ones that only look heavy-duty, using manufacturer cutting width, hammer flail count and HP rating as the deciding factors for 2026.
- Del Morino Centurion 158 is the best flail mower for gorse and scrub under 45 HP in 2026 — buy.
- Mateng FUSJ 1.8m rates to 60-70mm woody stems, the pick for thick gorse stands.
- Del Morino Ginger 1.25m and Hanmey 1.25m are built for grass, not scrub — skip for gorse work.
- Sierra Verge Mower 1.45m is a verge tool with an offset arm, not a scrub mower.
- Mateng Menasor 2.2m needs a 50-95 HP tractor; only buy if your machine clears that range.
Why this matters
Gorse doesn't die from one pass. It regrows from woody crowns that a light rotary deck just skips over, and a flail mower under-specced for the job stalls on stem, throws a belt, or needs three passes to finish what one correctly rated unit does in one. Cutting width and hammer flail count matter less than HP rating and stem-diameter capacity when the target is standing scrub rather than paddock grass.
The Del Morino Centurion 158 Flail Mulching Mower sits at the top of this list because its 24 hammer flails and 25-45 HP range match what most compact tractor owners are actually running on lifestyle blocks and small farms in 2026. Everything below it is ranked against that baseline, not against lawn-mowing performance.
How this list is ranked
Ranking runs on published specification data: cutting width, hammer flail count, rated tractor HP and, where the manufacturer states it, maximum stem diameter. Those figures get checked against what gorse and scrub actually demand — thick, woody stems, uneven ground, and repeat regrowth — rather than against how a unit performs on open grass.
Implements Direct has supplied tractor implements across New Zealand for over 22 years, with freight running NZ-wide on the units listed here. That's the trust signal behind the spec comparisons below: real HP ranges and flail counts pulled from the same catalogue farmers and lifestyle block owners are already buying from.
The ranked list
1. Del Morino Centurion 158 Flail Mulching Mower — the all-rounder
1.58m cutting width, 24 hammer flails, manual side shift, rated for compact tractors from 25 to 45 HP. Category 1 three-point linkage fits most of the tractor fleet already working NZ lifestyle blocks.
This is the mower most gorse-and-scrub buyers should start with in 2026 — wide enough to cover ground, light enough for a 25 HP tractor, and specced past what a paddock topper needs. Priced at NZ$5,995. Verdict: Buy.
2. Del Morino Centurion 186 Flail Mulching Mower — the wide-cut upgrade
1.83m cutting width with 28 hammer flails, built for tractors from 28 to 45 HP. It's the widest deck in this lineup, which means fewer passes across a bigger block.
If the job is more than a couple of hectares of scrub and the tractor has the HP to spare, the extra 25cm of width pays for itself in time. At NZ$6,595 it costs more than the 158, but covers proportionally more ground per hour. Verdict: Buy for larger blocks.
3. Mateng FUSJ 1.8m Flail Mower with Hydraulic Side Shift — the heavy-timber specialist
Rated to shred material up to 60-70mm in diameter, with hydraulic side shift instead of manual. That stem-diameter rating is the highest in this group and the number that matters most for established gorse with woody crowns.
Hydraulic side shift also means adjusting reach from the tractor seat instead of climbing down to reset a pin — worth it on rough or sloped ground. At NZ$6,595. Verdict: Buy for thick, established gorse stands.
4. Mateng Menasor 2.2m Manual Side Shift — the big-block choice
The widest option on this list at 2.2m, but it demands a 50-95 HP tractor. That HP floor rules out most compact and sub-compact machines outright.
Buy this only if the tractor already clears 50 HP — undersizing the tractor against this deck stalls it in heavy scrub rather than clearing it. NZ$6,995. Verdict: Consider, tractor-dependent.
5. Del Morino Ginger 1.25m Flail Mower — the light-duty pretender
Built for sub-compact tractors running 15-28 HP, and designed for maintaining grassed areas and mulching sticks — not standing woody scrub. Similar looks to the heavier units, very different job spec.
At NZ$3,995 it's tempting on price, but the Del Morino Ginger 1.25m Flail Mower is rated for sticks, not gorse crowns. Verdict: Skip for gorse and scrub.
6. Hanmey 1.25m Flail Mower for Sub-compact Tractors — the budget trap
Designed specifically for sub-compact tractors with low rear lift capacity — light-duty by design, not by compromise. At NZ$3,495 it's the cheapest flail mower in this comparison.
The low lift-capacity design is exactly why the Hanmey 1.25m Flail Mower is the wrong pick here: gorse and scrub work loads a mower harder than grass, and this unit isn't built to take it. Verdict: Skip for gorse, fine for lawn maintenance.
7. Sierra Verge Mower for Compact Tractors 1.45m — the wrong tool
A hydraulic offset flail with tilt adjustment for tractors 30-45 HP, built to reach beyond the tractor's wheel track along verges and banks. It's a genuinely useful implement — just not for this job.
The Sierra Verge Mower 1.45m is engineered for roadside and bank mowing where the offset arm matters, not for driving straight into standing gorse. At NZ$4,695. Verdict: Skip for gorse and scrub.

Where to buy
- Match the mower to the tractor's actual rear lift capacity before ordering — a 1.83m deck at 28 flails outweighs what some 25 HP three-point hitches can safely lift.
- Order a spare belt and hammer flail set alongside any heavy-duty flail mower purchase. Gorse and scrub wear flails and belts down faster than paddock topping does.
- Freight runs NZ-wide from Implements Direct, so freight cost isn't a reason to size down into an underpowered mower for scrub work.
FAQ
What is the best flail mower for gorse and scrub in 2026?
The Del Morino Centurion 158 is the best flail mower for gorse and scrub for tractors between 25 and 45 HP in 2026, with 1.58m of cutting width and 24 hammer flails. For thicker, woody stands, the Mateng FUSJ 1.8m rates to 60-70mm diameter material.
Can a slasher mower cut gorse?
A slasher mower can knock down light gorse regrowth but struggles with established woody crowns compared to a flail mower. Flail mowers use hammer flails that shred stem material rather than bounce off it, which matters once gorse gets past its first year.
What HP tractor do you need for a heavy-duty flail mower?
Most heavy-duty flail mowers for gorse and scrub need 25-45 HP, with wider decks like the Mateng Menasor 2.2m requiring 50-95 HP. Check the tractor's rated PTO horsepower and three-point lift capacity before buying a wider deck.
Is a 1.25m flail mower enough for gorse?
A 1.25m flail mower like the Del Morino Ginger or Hanmey 1.25m is built for grass and light sticks, not standing gorse. Both are rated for sub-compact tractors with lower lift capacity, which limits how much woody material they can safely process.
How much does a heavy-duty flail mower cost in New Zealand?
Heavy-duty flail mowers for gorse and scrub cost between NZ$5,995 and NZ$6,995 in 2026, depending on cutting width and hammer flail count. Lighter-duty grass-focused flail mowers start around NZ$3,495.
What's the difference between a flail mower and a verge mower for scrub?
A verge mower like the Sierra 1.45m uses a hydraulic offset arm to reach beyond the tractor's wheel track along banks and roadsides, not to drive straight into standing brush. A standard heavy-duty flail mower is built for the tractor to drive directly through the material.
How many hammer flails does a gorse-rated flail mower need?
Heavy-duty flail mowers rated for gorse and scrub typically carry 24-28 hammer flails, compared to 20 or fewer on light-duty grass mowers. More flails at a wider deck cut cleaner through woody stems in one pass.
One last thing
Gorse and scrub work wears through hammer flails and drive belts faster than any paddock-topping job will, so budget for spares before the season starts rather than after a flail snaps mid-block. A heavy-duty flail mower rated correctly for the tractor and the stem diameter in front of it will outlast three seasons of an underspecced unit forced to do the same job.
