Our verdict
The right Stihl for buyers who already own the AK home-and-garden range. The battery slots into all your other Stihl tools — that's the actual reason to buy. Otherwise the EGO 47cm at the same price obliterates this on cut width and runtime.
Pros & cons
Pros
- Stihl AK battery shared with home tools (hedge trimmer, blower, strimmer)
- Lighter and quieter than the AP-system mowers
- Mulch plug standard
- Stihl quality for an urban lawn
Cons
- 37cm cut tiny
- AK battery sold separately — adds £80+
- Limited runtime on a single AK 30 battery

Buying second-hand
£100–180 used (always confirm battery is included). Stihl AK batteries have a 5-pin lock — check the lock clip is firm. AK batteries lose 25% capacity by year 4; demand a runtime test. Stihl chassis number checks confirm warranty status.
