Petrol vs battery brush cutter: which should you buy?
It's the biggest decision when buying a brush cutter. Here's a side-by-side look at power, runtime, noise, upkeep and cost — and who each type suits.
In short:Petrol brush cutters run as long as you have fuel and suit brambles, big plots and long days — from the 27.2 cc Stihl FS 55 to the 1.4 kW FS 131 or 52 cc Fuxtec FX-MS152 — but need fuel mixing or oil checks, servicing and ear protection. Battery machines start instantly and are quieter, with runtime set by the pack: Ryobi quotes up to 47 minutes of brush cutting for its RBC36X26B, Stiga up to 60 for the BC 700e. Strong cordless models now take metal blades.
Both types cut grass and brush, but they suit different owners. Petrol gives unlimited runtime and the most power for big jobs; battery is quiet, clean and low-maintenance.
Side by side
| Petrol | Battery (cordless) | |
|---|---|---|
| Runtime | Unlimited — refuel in seconds | Per pack — e.g. up to 47 min (Ryobi) or 60 min (Stiga) |
| Heavy clearing | Up to 1.4–1.5 kW (FS 131, EM4351UH, GC-BC 52) | Blade machines for light scrub |
| Noise & fumes | Loud, exhaust (e.g. 110–115 dB(A) declared) | Quieter, no fumes |
| Upkeep | Fuel mix or engine oil, filters, plugs | Charging, cleaning |
| Starting | Pull start (eased by ErgoStart, Smart Start) | Trigger |
| Weight | 4.4 kg (FS 55) to 8.7 kg (GC-BC 36-4 S) | 2.7 kg (EGO ST1300E, bare) to 6.75 kg (GP-BC 36/430) |
Choose petrol if…
You have brambles, scrub, a large plot, or you cut for hours. Good picks: the semi-pro Stihl FS 131, the mix-free Honda UMK 435 or the budget Fuxtec FX-MS152. See all petrol brush cutters.
Choose battery if…
You have a small-to-medium plot, neighbours nearby, or dislike engine upkeep. Good blade-capable picks: the Ryobi RBC36X26B kit and Makita DUR369AZ. See all cordless brush cutters.
The verdict
For most gardens, a strong cordless machine is the easier life. Choose petrol when brambles, acreage or long days demand it. Not sure? Try our brush cutter matcher.

The three petrol machines run all day on a tank of fuel; the three cordless machines take a metal blade and are quiet enough for a housing estate.
Frequently asked questions
Is a petrol or battery brush cutter better?
Petrol wins on runtime and on heavy clearing over big plots. Battery wins on noise, fumes, starting and upkeep. For grass and light scrub on small-to-medium plots, a strong cordless machine with a blade now covers most homeowner jobs.
Can a battery brush cutter replace a petrol one?
For many gardens, yes. Machines like Makita's twin-18V DUR369AZ (430 mm line, 255 mm blade) or Ryobi's RBC36X26B (26 cm 3-tooth blade) handle tall grass and light scrub. For thick, established brambles across a large area, a petrol machine like the 1.4 kW Stihl FS 131 is more capable.
How long does a battery last?
It depends on the battery and the work. Ryobi quotes up to 47 minutes of brush cutting from the RBC36X26B's 4.0 Ah battery; Stiga up to 60 minutes from a 4 Ah battery on the BC 700e. A spare battery doubles that.
Which is cheaper overall?
Petrol is often cheaper upfront for the power, but needs fuel, two-stroke oil or engine oil, and servicing. Cordless costs more if you have to buy batteries, but almost nothing to run.
