The STIHL RMA 239 C is aimed at homeowners with small to medium-sized lawns who want a compact cordless mower with straightforward controls and easy-to-store features. Its 37 cm cutting width and 40-litre catcher suit routine domestic mowing, while STIHL estimates approximately 250 m² of coverage with its recommended AK 20 battery. That is manufacturer guidance, not a guaranteed area for every lawn. T3 named it the most user-friendly cordless mower in its 2026 selection, but this review is based on published specifications and that attributed assessment—not personal operation of the mower.

What kind of lawn is the RMA 239 C for?

STIHL positions the RMA 239 C for small to medium-sized lawns. The manufacturer says the recommended AK 20 battery covers approximately 250 m². The actual area a charge will manage can vary with grass length, moisture, terrain and mowing conditions, so treat the figure as a planning estimate rather than a promise.

Its 37 cm cutting width is a practical fit for smaller gardens and tighter spaces. A narrower deck may mean more passes on a larger lawn than a wider mower would require; that is a trade-off to weigh against compactness and manoeuvrability.

Cutting, collection and storage

Cutting height

STIHL lists six central cutting-height positions, from 20 mm to 70 mm. This is the mower’s adjustment range, not evidence by itself of a particular cut quality. The instruction manual for the related RMA 239.1 C says cutting resistance can rise in long grass; if the mower encounters too much resistance, it advises raising the cutting height or mowing shorter grass.

Grass collection

Handle and storage

The height-adjustable mono-handle folds, a design intended to make storage easier and improve access to the catcher. These features address practical handling and storage needs, but published specifications alone do not establish how the mower feels to use in a particular garden.

Battery, weight and package details

The mower uses STIHL’s AK battery system, and STIHL recommends an AK 20 for its approximately 250 m² working-area estimate. Check what you already own before comparing the cost of a mower package: the cited UK listing distinguishes a tool-only configuration, which excludes the battery and charger, from a set. Package contents can vary by listing, so confirm them with the specific seller.

STIHL UK lists the mower at 15 kg without the battery. The RMA 239.1 C instruction manual specifies 15 kg with the catcher fitted and without the battery. The manual applies to that named variant; do not assume every regional version has identical specifications.

What the independent review says

T3’s 2026 roundup labels the mower “The best user-friendly cordless mower” in its selection and says its reviewer was particularly impressed by efficiency and results. T3 also reports a 40-minute average runtime. That is an editorial report, not a manufacturer guarantee or a controlled measurement reproduced here; runtime in practice depends on the conditions and battery used.

Specifications at a glance

Who should consider it?

  • A plausible fit: You have a small or medium lawn, value a compact 37 cm deck, and either own a compatible AK battery or have budgeted for the correct kit.
  • Check carefully: Your lawn is near or above STIHL’s approximate 250 m² estimate, or you need a runtime assurance. The published coverage figure is conditional, and T3’s runtime is an editorial report rather than a guarantee.
  • Compare alternatives: You mow a larger area and want to assess whether a wider deck, larger catcher or different battery package better suits the work. Compare area guidance, battery inclusion, weight configuration, height range and storage design—not just headline runtime claims.

Verdict

The RMA 239 C looks well matched to the homeowner seeking a compact, uncomplicated cordless mower for a modest lawn. Its manufacturer-listed cutting range, folding handle and catcher, and fill-level indicator address useful everyday details; T3’s 2026 recognition adds an independent note of user-friendliness. The key decision is whether its scale and battery arrangement suit your garden. Check the exact STIHL RMA 239 C cordless lawn mower package before buying, particularly whether it includes a battery and charger.
