How to choose a brush cutter
The complete 2026 buying guide — everything that actually decides which machine is right for your land, in plain English.
In short:To choose a brush cutter, start with your toughest growth and plot size. For lawns and edges, a light line trimmer is enough. For nettles, tall grass and light scrub, choose a machine that takes a metal blade — cordless if you own batteries from that brand, petrol for long sessions. For brambles and big plots, choose petrol from about 1 kW with a bike handle and harness. Corded machines suit small plots near a socket. On Amazon.co.uk in October 2026, prices ran from about £40 for corded trimmers to £300+ for premium machines.
Buy the right brush cutter and it'll serve you for a decade. Buy the wrong one and you'll either fight an underpowered machine or lug around power you never use. This guide walks you through the handful of decisions that really matter — no jargon, no upselling.
Step 1: Petrol, battery or electric?
This is the biggest fork in the road. Each technology has a clear sweet spot:
| Type | Best for | Strengths | Limits |
|---|---|---|---|
| Petrol | Tough land, brambles, big plots, all-day use | Maximum power, unlimited runtime | Noise, fumes, maintenance, weight |
| Battery | Small–medium plots, low-fuss use | Quiet, mobile, zero engine maintenance | Runtime limited by battery |
| Electric (corded) | Small plots near a socket | Cheapest, light, unlimited runtime | Tied to a cable and socket |
For most homeowners today, a good 36V–40V cordless machine is the sensible default. Step up to petrol only if you genuinely face brambles, scrub or acreage.
Step 2: The 5 criteria that decide your choice
1. Plot size
Small (under ~500 m²) → 18V battery or corded electric. Medium (500–2000 m²) → 36V/40V battery. Large (2000 m²+) → petrol or pro cordless.
2. Type of vegetation
Normal grass → a line head is enough. Tall grass → line plus a blade. Brambles and scrub → petrol from 27 cc, or a strong cordless with a steel blade.
3. How often you'll use it
Occasional (once or twice a month) → electric or 18V battery. Regular → 36V battery. Intensive → petrol or professional.
4. Realistic budget
Prices on Amazon.co.uk when we checked in October 2026: under £100 → corded trimmers (Black+Decker GL360 £39.99, Bosch EasyGrassCut 23 £71.05), bare cordless trimmers or the 25 cc Fuxtec FX-MS125 (£81.49). £100–200 → 52 cc budget petrol (Fuxtec FX-MS152 £109, Einhell GC-BC 52 £138.66) or a bare twin-battery brush cutter (Einhell Agillo 36/255 £158.99). £200–350 → branded petrol (Stiga BC 535 B £209, Husqvarna 129R £309) or Makita twin-battery machines. Stihl and Honda are priced by dealers. See our price-band guides.
5. Noise and neighbours
A housing estate with strict hours makes cordless almost essential. Isolated land? Petrol is no problem.
Step 3: Line head vs metal blade
The cutting attachment matters as much as the engine. A nylon line head is for grass and soft growth. A metal blade is for anything woody: a 3-tooth or 4-tooth blade for brambles and scrub, a circular-saw or 8-tooth blade for saplings. The most versatile machines accept both — check that the model supports a blade if brush is on your list.
Step 4: Handles, harness and comfort
A loop handle is nimble for trimming around a garden; a bike (bull-horn) handle gives control and reach for sweeping across open ground with a blade. For anything beyond light work, use the harness — it transfers weight off your arms and makes long sessions far safer and less tiring. Anti-vibration mounts are worth having if you'll cut for hours.
Step 5: Safety essentials
- Always wear eye protection, ear defenders, sturdy boots and long trousers (ideally cut-resistant for blade work).
- Keep bystanders well clear — thrown debris travels far and fast.
- Use a harness for blade work, and never cut above waist height.
- For corded electric, use an RCD-protected socket or lead and never work in the wet.

Frequently asked questions
Petrol, battery or electric — which is best?
It depends on your land. Petrol for tough growth, big plots and all-day use; battery for quiet, low-maintenance convenience on small-to-medium plots; corded electric for the lowest price on a small plot near a socket.
What is the difference between a brush cutter and a string trimmer?
A string trimmer uses only nylon line and is for grass and edging. A brush cutter is more powerful and can take a metal blade, letting it cut brambles, scrub and woody growth. Many machines can do both by swapping the head.
What power do I need for brambles?
A metal blade plus real torque: a petrol machine from about 1 kW (such as the Stihl FS 131 or Stiga BC 545 B), or a strong twin-battery cordless with a blade such as the Makita DUR369AZ. Line-only trimmers cannot handle brambles.
Do I need a blade or is line enough?
Line is fine for grass and soft growth. For anything woody — brambles, saplings, thick stems — you need a metal blade: a 3- or 4-tooth blade for brush, a saw blade for saplings, where your manual allows.
How much should I spend?
On Amazon.co.uk in October 2026: under £100 buys a corded or bare cordless trimmer or a 25 cc petrol starter; £100–200 a 52 cc budget petrol machine or a bare twin-battery brush cutter; £200–350 branded petrol or Makita twin-battery machines. Stihl and Honda are priced by dealers. Buy for your worst growth, not your average.
