Stihl RMA 443 CORDLESS PUSH LAWN MOWER

STIHL RMA 443 Cordless Lawn Mower is a 41cm battery mower aimed at home users who want more coverage than a compact cordless model without stepping up to a bigger, heavier machine. The RMA 443 is a push-along mower in the STIHL AK System, built around quiet running, low fuss maintenance and practical features that make regular mowing easier.

For many Suffolk Mowers customers, the big appeal is how much this mower gives you in a manageable format: four mowing options, dual battery slots, a 52-litre grass box and a mono handlebar that makes emptying simpler. If you already use AK System tools, it makes even more sense, and if you need more assistance on bigger areas, the RMA 443 V is the next step up with self-propulsion.

Built for Proper Home Lawns

The STIHL RMA 443 sits in that middle ground a lot of people are actually looking for — more capable than small entry-level cordless mowers, but without the size and weight of larger 46cm+ machines. With a 41cm cutting width, it covers ground efficiently while still being easy to handle around borders, trees and tighter areas.

If you’re mowing regularly and keeping the lawn under control, the RMA 443 handles it comfortably. It’s not trying to be a heavy-duty petrol replacement — it’s designed for consistent, clean cutting on maintained lawns where ease of use matters just as much as performance.

Four Cutting Options Without the Hassle

One of the stronger points on the RMA443 is how flexible it is straight out of the box. You’re not locked into one mowing style:

• Cut & collect for a clean finish
• Rear discharge when you want to move quicker
• Side discharge for longer grass or less formal areas
• Mulching mode to return nutrients back into the lawn

Switching between modes doesn’t involve tools, which makes it far more likely you’ll actually use the different options rather than sticking with one setup all season.

Dual Battery Slot – Less Stopping, More Mowing

This is something a lot of buyers overlook until they use it. The Stihl RMA 443 has space for two AK batteries, so when one runs out, you can switch straight over and keep going. No walking back to the garage mid-job.

With an AK 20, you’re looking at around 230m², but stepping up to an AK 30 or AK 30 S pushes that further. If you’re already using the STIHL AK system, it’s an easy upgrade without buying into a new platform.

Comfort Where It Actually Matters

The mono handlebar isn’t just a design choice — it makes day-to-day use easier. You’ve got clear access to the grass box, so removing and refitting it is quicker and less awkward compared to traditional twin-handle setups.

The 52-litre grass catcher is a good size for this class, and the fill level indicator stops you from overfilling or checking it constantly. It opens fully as well, so you’re not fighting to empty compacted clippings.

Lightweight Build That Holds Up

The polymer deck is worth pointing out properly. It keeps the weight down while still handling regular use, and it won’t rust like steel decks can over time. It’s also UV resistant, so it holds up better if the mower is stored in a shed or garage with light exposure.

At around 24kg without the battery, the RMA 443 stays manageable for most users, especially compared to larger cordless or petrol models.

Consistent Power Without Drop-Off

One of the common complaints with cheaper cordless mowers is how they fade as the battery drains. The RMA 443 avoids that. It maintains steady performance throughout the charge, so you don’t end up with a weaker cut halfway through the lawn.

Eco mode helps stretch runtime further by adjusting output to match the conditions, which is useful on lighter cuts where full power isn’t needed.

Where It Sits in the Range

The STIHL RMA 443 is a clear step up from smaller cordless models, giving you more cutting width and better overall capability. If your lawn is pushing beyond what a compact mower can handle, this is where most people land.

If you need less effort pushing, the RMA 443 V adds self-propelled drive. If you’re dealing with larger lawns again, moving up to wider models in the range makes more sense. For heavier, less maintained ground, petrol is still the better option.

Support, Batteries & Ongoing Use

Buying from Suffolk Mowers means you’re not just getting the mower — you’ve got access to parts, servicing and advice when you need it. That matters with cordless kit, especially when it comes to battery choice and getting the most out of the machine.

This tool-only version is ideal if you already own STIHL AK batteries. If not, it’s worth looking at the kit version with battery and charger to get started properly.
