The only STIHL lawn mower you can reliably buy online is the RMA 235 set, complete with an AK 20 battery and AL 101 charger — and within its limits it is a lovely thing: STIHL build quality, a mower that arrives charged and ready, on a battery system that also runs the brand’s hedge trimmers and blowers. Its limit is size. If your lawn is a normal suburban half acre, the mower you actually want is the RMA 510 V— full-size deck, variable-speed drive, on the bigger AP system — or the push RMA 460 below it, and both are dealer purchases we link you to check rather than price.
STIHL is a dealer brand by design, and our 13 October 2026 catalog pass reflects that exactly: searching the range returned AK 10 batteries, AK 20 packs and a lot of other brands’ mowers. The one real STIHL machine was the RMA 235 kit, in stock with a verified price. That is the honest shape of the brand’s online availability.
The thing to get right with STIHL is not the mower, it is the battery system, because that decision outlasts the purchase. AK is the compact homeowner system: lighter, cheaper packs, a broad range of small tools, and the system the RMA 235 runs on. AP is the professional system: far more capacity, the full-size mowers, the pro trimmers and the chainsaws. They do not share packs. Whichever one your mower is on becomes the system every future STIHL tool you buy belongs to, so pick the system first and the mower second.
We have mown with none of these. The ranking reasons from published specifications — deck class, battery system, drive type, what is included in the box — see how we pick.
STIHL mowers compared
| Mower | Battery system | Deck | Drive | In the box | Price source |
|---|
| RMA 235 set | AK 36V | Compact | Push | AK 20 + AL 101 charger | Live price |
| RMA 460 | AP 36V | Full-size | Push | Usually bare tool | Dealer — check price |
| RMA 510 V | AP 36V | Full-size | Variable-speed self-propel | Usually bare tool | Dealer — check price |
| Greenworks 60V 21" SP | Greenworks 60V | 21 in | Self-propelled | 2 x 4.0 Ah kit | Live price |
| EGO LM2114SP | EGO 56V | 21 in | Self-propelled | Battery + charger | Live price |
Battery systems, deck classes and drive types above are the figures the listing and STIHL’s published specifications state. The two AP-system mowers carry no price because no verified live listing exists for them.
AK or AP: pick the system before the mower
This is the decision that deserves your first five minutes, because it is the one you cannot undo cheaply.
AK is the right choice for a small lawn and a handful of garden tools.The packs are light and affordable, the tool range is genuinely broad — hedge trimmers, small blowers, string trimmers — and the RMA 235 is a pleasant mower to use. Its ceiling is capacity: on anything approaching a suburban half acre, an AK pack runs out before the lawn does.
AP is the right choice if the lawn is normal-sized or the tools are serious. More capacity, the full-size RMA mowers, and the professional trimmers, blowers and saws. It costs more at every step and it is the system to be on if a STIHL mower is your main mower rather than a second one.
What you should not do is buy an AK-system mower for an AP-sized lawn because it was the one available online. That is the mistake this page exists to prevent.
Which STIHL mower for which lawn
Up to about 4,000 square feet, flat: the RMA 235 set. It is the only one you can order with a price in front of you, it arrives with a battery and charger, and at that lawn size its deck and pack are adequate.
A normal suburban lawn, flat:the RMA 460 — full-size deck, push, AP system. Expect to buy the pack and charger separately at a dealer, which is a substantial addition.
A normal suburban lawn with a slope: the RMA 510 V. Variable-speed self-propelled drive is what a gradient actually needs, and it is the difference between mowing the lawn and putting it off. The general case is in the self-propelled roundup.
Past about three-quarters of an acre: no walk-behind, STIHL or otherwise. See the riding mower roundup.
When the honest answer is a different brand
STIHL build quality is real and so is the dealer support. But on price per unit of deck width, in this channel, it is not close. The Greenworks 60V 21" self-propelled arrives as a twin-battery kit with a full-size deck for a fraction of what a comparable STIHL costs all-in, and two packs is what actually decides whether you finish a lawn. The EGO LM2114SP is the premium-feeling alternative with the deepest cordless tool range in the category behind it.
Both are ranked against the whole field in best electric lawn mower. Where STIHL earns the premium is if you already own AK or AP batteries, if you value a dealer who sets the machine up and services it, or if you are buying a system for serious tools and the mower is one part of it. Those are good reasons. “It is the one Amazon had” is not.
Who should skip these
Skip the RMA 235 if your lawn is over about 4,000 square feet. Both the deck and the AK pack run out before a suburban half acre does.
Skip STIHL entirely if you own batteries on another platform — reusing packs beats any brand difference.
And skip the AP-system mowers if you want to buy today at a visible price. They are dealer products, and that is a feature of how STIHL sells rather than something we can work around.
