In short:The DeWalt DCM571 is a 54V FlexVolt brushless trimmer with a 38 cm cut and two speed ranges; UK kits add a brush-cutter adaptor and blade, and the bare tool weighs about 4.6 kg. The EGO BCX3800 is EGO's 56V commercial brush cutter with a 2 kW brushless motor, bike handle, carbon-fibre drive shaft, 38 cm line cut and a supplied 30 cm three-blade steel cutter; one UK retailer lists it at 6.5 kg. Both are sold bare; your battery platform decides.

Blade work
The EGO is designed as a brush cutter first: a bike handle for two-handed control, a three-blade steel cutter supplied and a 2 kW motor to drive it. The DeWalt is a trimmer that converts: UK X1 kits include a brush-cutter adaptor and blade, and DeWalt lists the DT20654 blade for the bare tool. For regular blade work on brambles and scrub, a bike handle and harness make a real difference to control and fatigue — see loop vs bike handle.
Weight
The DeWalt is the lighter tool at about 4.6 kg before its battery. One UK retailer lists the EGO at 6.5 kg. Both get heavier with a battery fitted, so a harness is worthwhile for either on long sessions.
Batteries
Most versions are sold bare. DeWalt’s FlexVolt batteries also run its 18V XR tools, which suits trade users with DeWalt kit. EGO’s 56V batteries run its mowers, blowers and chainsaws. Whichever platform you already own will usually decide this — starting a second platform costs more than the gap between the tools.
Which should you buy?
For regular scrub clearing with a blade, the EGO BCX3800’s bike handle, supplied steel cutter and 2 kW motor make it the more purpose-built brush cutter. For a lighter machine that’s mostly a powerful trimmer with blade capability for occasional scrub — especially if you already own FlexVolt batteries — the DeWalt DCM571 makes more sense. For heavy, all-day clearing, compare with petrol in petrol vs battery.
Frequently asked questions
Which is the more serious brush cutter?
The EGO BCX3800 is built as a commercial brush cutter: a 2 kW brushless motor, a bike handle, a carbon-fibre drive shaft and a 30 cm three-blade steel cutter in the box. The DeWalt DCM571 is a powerful 54V trimmer that becomes a brush cutter with the adaptor and blade supplied in UK X1 kits, or the DT20654 blade for the bare tool.
Do they come with batteries?
The versions most UK retailers sell are bare: the DCM571N and the BCX3800 body only. DeWalt also sells the DCM571X1 kit with a 3.0 Ah or 9.0 Ah FlexVolt battery. Budget for batteries if you're new to either platform.
