Key Features in Detail
Constant Power Electronics
Unlike many battery tools that lose power as the battery discharges, STIHL’s intelligent electronics ensure the RMA 235.1 works with consistently high power from start to finish, providing a reliable cut every time.
Polymer Housing
The mower’s housing is constructed from a high-quality polymer that is not only exceptionally light but also highly resilient and robust. It is resistant to petrol and protects the engine block from UV radiation, ensuring long-term durability.
Flow-Optimised Blades
The specially designed blades trim grass with minimal air resistance. This energy-efficient design means the mower uses less electricity, allowing you to mow larger areas on a single charge by making optimal use of the stored energy.
Folding Grass Collection Box
Emptying grass clippings is straightforward thanks to the folding 30-litre collection box. A built-in fill-level indicator signals the right time for emptying. The design promotes dense filling, and side slats direct air towards the ground, protecting the operator from swirled-up dirt.
Easy Transportation and Storage
A practical, integrated carry handle makes the mower very easy to lift and transport. Combined with the foldable handlebar, storing the RMA 235.1 in a shed or garage is quick, easy, and compact.
