Our verdict
The first credible cordless zero-turn for residential UK buyers. The ZT4204E does what a petrol zero-turn does at a fraction of the running cost and noise. If you have a flat, 5000-8000m² lawn and don't need to collect clippings, this is the future-proof buy. For ride-on plus collector, you still need petrol or a Husqvarna Automower.
Pros & cons
Pros
- Zero-turn manoeuvrability
- Cordless — no fuel, no oil, no winter prep
- EGO 56V batteries shared across the range
- Quiet at 78 dB compared to 100 dB petrol equivalent
Cons
- £5.5k upfront is a serious commitment
- 8000m² per charge — replace batteries mid-job on bigger plots
- Mulch-only — no grass collection
- Battery replacement £200 each, x4 in 10 years = £800
