STIHL RMA 239 C Cordless Lawn Mower – 37cm AK System

Is the STIHL RMA 239 C Right for Your Lawn?

The STIHL RMA 239 C cordless lawn mower is designed for homeowners who want a manageable, cable-free mower for a small to medium-sized lawn. Its 37cm cutting deck is wide enough to cover a typical family lawn efficiently but remains compact enough to manoeuvre around borders, trees, paths and garden features.

This is a hand-propelled push mower powered by STIHL’s 36V AK battery system. It has a low machine weight of 15kg without the battery, a folding mono-comfort handlebar and an integrated carrying handle, making it easier to move and store than a wider steel-deck mower.

With the recommended STIHL AK 20 battery, the mower can cover up to approximately 250m² per charge. Actual coverage varies with grass length, moisture, lawn condition, cutting height, battery condition and mowing technique.

Why Masseys Recommends the STIHL RMA 239 C

At Masseys, we recommend the RMA 239 C to customers who want more cutting capacity than a very compact 33cm mower but do not need the size and weight of a larger steel-deck machine. Its main strengths are the useful 37cm cut, 40-litre collector, low 15kg machine weight and the excellent mono-comfort handlebar.

The single-sided handlebar gives much clearer access to the grass box than a conventional two-sided handle. This makes removing and refitting the collector noticeably easier, particularly for customers who find lifting a grass box through a conventional handle frame awkward.

It is a particularly good match for relatively level lawns with borders, paths or obstacles where easy manoeuvring matters. Customers with a very small or confined lawn may prefer the lighter STIHL RMA 235. For larger open lawns, rougher conditions or customers wanting a heavier steel deck, consider the STIHL RMA 243 or STIHL RMA 248.

Key Features

37cm Cutting Width

The 37cm deck provides a practical middle ground between a very narrow mower for confined gardens and a heavier wide-deck machine. It covers more grass with each pass than the 33cm RMA 235 while remaining easy to turn around beds and garden features.

Six Central Cutting Heights

A single central control adjusts the cutting height through six positions between 20mm and 70mm. Raise the deck when the grass is longer or under stress and select a lower setting for a closer finish on a regularly maintained lawn.

Stream-Optimised Blade

The blade is designed to reduce unnecessary air resistance and use battery energy efficiently. The airflow also helps move cuttings into the collector for effective grass collection.

40-Litre Folding Grass Box

The 40-litre collector includes a fill-level indicator to show when it needs emptying. Its folding design opens for straightforward emptying, while the side vents direct air towards the ground rather than towards the user.

Mono-Comfort Handlebar

The single-sided mono-comfort handlebar provides clear access to the grass box. It can be adjusted to suit the user’s height without tools and folded down for more compact transport or storage.

Integrated Carrying Handle

A built-in carrying point makes it easier to lift the mower over steps, place it into storage or load it into a vehicle.

STIHL AK Battery Compatibility

The RMA 239 C uses interchangeable batteries from the STIHL AK System. The same battery platform can power compatible domestic garden tools, helping customers reduce the number of separate batteries and chargers they need to own.

Choose the Correct Package

Mower Only

Choose the mower-only option if you already own a suitable STIHL AK battery and charger. The recommended battery for the RMA 239 C is the STIHL AK 20 battery.

Mower with One AK 20 Battery and AL 101 Charger

This is the most suitable ready-to-mow package for customers who are new to the STIHL AK System. It includes the mower, one recommended AK 20 battery and one AL 101 charger.

Mower with Two AK 20 Batteries and One AL 101 Charger

Choose the two-battery package when you want the convenience of a charged spare battery. The batteries are used one at a time: when the first battery is depleted, it can be exchanged for the second. This option is useful where mowing conditions may reduce coverage or where the batteries will also be shared with other AK tools.

Battery Coverage and Charging

These are manufacturer test figures rather than guaranteed lawn sizes. Long, damp or dense grass, a low cutting height and repeated stopping or turning can reduce the area covered on one charge.

Technical Specifications

Battery coverage is approximate and varies according to battery charge, battery condition, grass length, moisture, cutting height, terrain and mowing technique. Manufacturer specifications may be updated without notice.

STIHL RMA 235 vs RMA 239 C vs RMA 243

Choose the RMA 235 for a genuinely small garden where minimum weight is the priority. Choose the RMA 239 C for its balance of manageable weight, useful cutting width and easy grass-box access. Choose the RMA 243 when you want a wider, heavier steel-deck mower with greater mowing versatility.

Build a Matching STIHL Cordless Garden System

Customers who choose an AK battery package can use compatible batteries across a range of domestic STIHL garden tools. Useful machines to pair with this mower include:

• STIHL FSA 60 R cordless strimmer for lawn edges, borders and areas the mower cannot reach.
• STIHL BGA 60 cordless leaf blower for clearing loose grass clippings, leaves and paths.
• The wider STIHL AK System range of domestic cordless garden machinery.

Frequently Asked Questions

How large a lawn can the STIHL RMA 239 C mow?

STIHL gives an indicative coverage of up to approximately 250m² with the recommended AK 20 battery. Actual coverage depends on the grass, lawn conditions, battery condition, cutting height and mowing technique.

Does the RMA 239 C include a battery and charger?

That depends on the package selected. Masseys offers the mower only, a package with one AK 20 battery and an AL 101 charger, and a package with two AK 20 batteries and one AL 101 charger.

Is the STIHL RMA 239 C self-propelled?

No. It is a hand-propelled push mower. Its 15kg machine weight makes it relatively manageable on level and gently sloping gardens, but customers wanting powered wheel drive should choose a self-propelled model.

What is the difference between the RMA 235 and RMA 239 C?

The RMA 239 C has a wider 37cm deck, a larger 40-litre grass box and a single-sided mono-comfort handlebar. The RMA 235 is lighter and more compact, making it better suited to very small lawns and confined garden layouts.

Can the RMA 239 C mulch?

The mower is supplied for grass collection. Mulching is possible when the compatible STIHL AMK 039 mulching kit is purchased and fitted separately.

Can I use an AK 10 or AK 30 S battery?

Compatible STIHL AK batteries can be used, but the AK 20 is the recommended balance for this mower. STIHL gives indicative coverage figures of approximately 120m² with the AK 10, 250m² with the AK 20 and 330m² with the AK 30 S.

Is the RMA 239 C suitable for wet or very long grass?

The mower performs best on regularly maintained grass in dry or lightly damp conditions. Long, dense or saturated grass increases the motor load, reduces battery coverage and can affect grass collection. Raise the cutting height and remove only part of the grass length where growth has become excessive.

Can Masseys service a STIHL cordless mower?

Yes. Masseys has an established garden-machinery workshop providing inspections, blade maintenance, servicing and repairs. Visit our machinery servicing and repairs page or contact the Masseys team for advice.
