What is the Stihl RMA 510 V?

The Stihl RMA 510 V electric mower is a battery-powered lawn mower. With rivals like Dewalt, Toro and Husqvarna producing electric walk-behind mowers, Stihl has finally made a strong entry into this category.

But here’s the crazy part—Stihl had never made a push mower before they entered into the electric mower market. Brands like Toro have experience with gas mowers and could easily swap out a combustion engine for an electric motor without a problem. Stihl started from the ground up.

These days, it isn’t all that unusual to see a new electric mower hit the market. There are probably hundreds of brands, but only a dozen or so with strong brand recognition and a reputation for quality.

How I Tested It

I tested the Stihl RMA 510 V in my backyard. This electric mower was designed for small to mid-size lawns for homeowners. But I like to go above and beyond when it comes to testing and don’t simply just mow my lawn.

Choke Out

I unboxed the Stihl RMA 510 V, assembled it and took it through the various tests. The first test is the “choke out” test. This involves finding a longer patch of grass that might make many electric mowers automatically cut off. I did this test on my lawn by dropping the deck height to one inch and pushing it through my four-inch-tall grass. The Stihl RMA 510 V did well with longer grass, probably because of the mulching blade that comes with the mower.

Maneuverability

The next test is maneuverability. The worst experience you can have when mowing is having difficulty making turns or navigating mulching beds. This self-propelled mower weighs about 65 pounds, but it made light work of many of the mulching beds.

Speed

The last test is the speed test. I turned the self-propelled speed up to the fastest setting and mowed a straight line in my lawn. I then turned it down and mowed a separate line right next to the “fast” line. After, I went back through and looked to see how the cutting performance compared. The lines looked identical, meaning the “fast” line did not miss any blades despite moving much more quickly.

Stihl RMA 510 V Features

After putting this mower through my backyard testing process, here are some of the key observations I had on each of the features of the Stihl RMA 510 V.

Assembly

I have had many mowers in the past with frustratingly difficult assembly instructions. I assembled a no-name brand mower a few months ago and gave up on getting the “cool” folding storage component because it simply could not be assembled.

Assembling the Stihl RMA 510 V was a breeze. It looks complex on the outside, given that it has wires and coils coming down the front of the mower, but it was a simple attachment of the deck to the handlebars. I had to hand-tighten a few screws and ensure the proper handlebar height, but otherwise, the assembly process was very smooth.

The RMA 510 V came with a battery, a charger and a grass collection bag in addition to the mower itself. I don’t often use a grass collection bag, so this went into storage, but using the battery and charger was completely effortless.

Starting the Mower

The Stihl RMA 510 V is similar to many electric mowers. A safety “squeeze” bar exists on the upper right-hand side of the handlebar. To start the mower, you simply pull the safety bar together with the handlebar and press the ignition button on the side.

Before you start the mower, ensure it has enough battery life and that you’ve set the cutting adjuster to the proper height. The Stihl RMA 510 V has a range of one to four inches of cutting height. The cutting height range is perfect for just about everyone. I like to keep the mower at the highest height to cut tall fescue, but you can adjust the height for short Bermuda, too.

Cutting Performance

The RMA 510 V fires right up when started, and pushing it forward is easy. I was not a proponent of self-propelled mowers for the longest time, especially when it came to electric self-propelled mowers. However, after using a few and having a positive experience, I can firmly say that I am addicted.

Taking this through my backyard felt like mowing through butter. The blades made quick work of my grass, even as I passed near some of my garden beds and beneath a tree that always drops debris. The 21-inch cutting deck provides 20 inches of cutting width, which is standard for just about every push and walk-behind mower.

One differentiator is a mulching blade that comes with the mower. Mulching blades allow for enhanced, fine chopping of grass blades that can enhance the nutrient profile of your lawn. I enjoy using the mulching blade and not placing the grass collection bag on the mower so that my lawn benefits from the nutrients.

Self-Propelled Function

A bar just above the normal handlebar controls the on and off features of the self-propelled function. On the left side of the handlebar, running along the side of the mower, is the variable self-propelled control.

The variable speed on the Stihl RMA 510 V controls how quickly you are mowing. Some self-propelled mowers can pull you forward, while others move too slowly. I like having total control over the speed of the mower so that I can walk at my own pace.

Battery Life

Batteries for the Stihl Electric MowerAlex K. for Family Handyman

The battery life on the Stihl RMA 510 V is also variable. I often struggle to provide a meaningful metric for battery performance, so I generally try to explain my experience. Battery life on lawnmowers is dictated by the type of grass when the grass is cut and the size of the yard. Further, adding in the self-propelled function also drains the battery and is variable depending on what speed the self-propelled function is set to.

My lawn is about a third of an acre in size, and I was able to cut all of it on one charge. Of note, I had almost zero juice left at the end of the mow. Afterward, I simply placed the battery back on the charger and went inside for the day.

Pros

  • 21-inch steel metal cutting deck is durable
  • Self-propelled function
  • Variable speed on the self-propelled function
  • Wide range of cutting heights

Cons

  • Fewer options in the battery line than in other brands
  • No headlights

What Other Reviewers Had to Say

I’m not the only one who has used and enjoyed the Stihl RMA 510 V. Take it from other buyers—the Stihl RMA 510 V has some serious positives that make it a highly reliable mower. Here are some common themes from other RMA 510 V users:

  • The mower is super quiet
  • The battery has lasted longer than advertised
  • Mulching blades breezed through leaves
  • Has a durable steel-cutting deck
  • Highly functional speed control

Stihl RMA 510 V vs. EGO Power+Touch Drive

Comparing the Stihl RMA 510 V and the EGO Power+ Touch Drive mower is a common question we get. Both of these mowers come from brands with amazing reputations for quality and performance.

These mowers both have a 21-inch cutting deck but differ in that Stihl has a steel metal cutting deck, whereas EGO has a hard plastic cutting deck. I prefer a steel cutting deck with my mower to ensure durability when mowing over rocks and sticks. I also like the added weight of a steel cutting deck to help provide control for the mower itself.

One other notable difference is the self-propelled functions between these two mowers. The EGO has a Touch Drive function that controls the speed with a quick swipe of the hand. The Touch Drive function is located right on the handlebar. The Stihl RMA 510 V has a speed control function as well, although it is located a little bit off to the side and is harder to reach.

Both mowers have great batteries, but I prefer the battery lineup on the EGO 56V mower because it has many more tools that fall into the same battery series. Stihl is slowly becoming a leader in battery-powered tools but has not yet built a lineup as robust as EGO.

Final Verdict

The Stihl RMA 510 V is a great electric mower for any homeowner with a mid-sized yard. I put this mower to the test in my backyard—through thick grass, speed testing and more. It stood up to every challenge I could think of and did so with grace.

Although Stihl is still emerging in the electric tool space, they have a long history of providing amazing lawn tools that are built to last. You can trust their brand reputation and knowledge. I recommend buying this electric mower if you have a small to mid-sized lawn.

What to Look for When Buying an Electric Lawn Mower

We asked expert Louis Danet, product manager at Stihl, what consumers look for when shopping for the best electric lawnmowers. Below are their buyer recommendations.

  • Run time: When choosing a battery-powered mower, the size of your yard and the type of grass you are cutting will help determine the necessary run time. You can opt for an entry-level mower or a more powerful model depending on your specific needs and preferences.
  • Cutting deck: Consider the cutting deck material—whether aluminum, steel, or polymer—as it can significantly impact the mower’s durability and performance. Steel decks are impact-resistant and ideal for commercial or demanding applications. Aluminum decks are lightweight and easier to maneuver, especially on uneven terrain. They’re also corrosion-resistant. Polymer cutting decks offer a lightweight, affordable option that is also resistant to rust and corrosion.
    • The size of the cutting deck depends on your yard and any obstacles present. Wider decks can mow more grass in less time, while narrower decks are better suited for maneuvering around obstacles and covering less ground more quickly.
  • Additional features: When purchasing a battery-powered mower, there are several variables to consider to ensure you select the best model for your needs. Decide between a self-propelled or push mower, as self-propelled models can reduce physical effort, especially on larger lawns.
    • Some mowers offer up to 4-in-1 capabilities, including mulching, grass bag collection, rear discharge and side discharge. An adjustable cutting height is essential for maintaining different grass types and achieving the desired lawn appearance. Ease of use is also key, with features like easy-start and an adjustable handle ensuring the mower can be tailored to the user for added comfort.
  • Brand reputation: Battery-powered mowers can come at a premium price point, so it’s important that you do your research and invest in a quality brand that offers a mower built to last.

What new electric mower features should buyers look for in 2025?

According to Danet, electric mowers have made significant strides as battery technology advances. This progress translates to longer run times and versatile battery platforms, where a single battery can power multiple outdoor tools. As technology advances in outdoor power equipment, consumers can expect newer models that offer longer run times and compatible chargers with faster charging capabilities.

Additionally, modern mowers are introducing new smart features such as intuitive LED displays to communicate battery life, Bluetooth capabilities and eco modes that automatically reduce power when mowing through light grass and adjust to full power in tall or thick grass to conserve battery life and extend run time. Some Stihl mower models come with Stihl Connected, which allows you to track a tool’s location, monitor run time, follow pre-installed maintenance schedules and more to help manage your tool fleet.

Mowers in 2025 will provide users with versatile options to tackle various tasks. One notable feature is a multi-blade design that effortlessly cuts and mulches your lawn, eliminating the need for blade changes while offering a consistent cutting pattern.

Lastly, the engineering and design of electric mowers have also evolved. For instance, Stihl recently introduced their signature mono-comfort handlebar, which provides convenient, unobstructed access to the polymer grass bag.
