Yard Force LM G34A 40V Cordless Lawnmower (34cm, Rear Roller)

Yard Force LM G34A 40V Cordless Lawnmower (34cm, Rear Roller)

Cordless Rotary Lawnmower

From: Yard Force

The 40V 34cm Cordless Lawnmower LM G34A cuts a 34cm wide path and suits lawns up to roughly 350 square metres. A brushless motor with Torque Sense Boost Technology drives the blade, giving steady power without a cable getting in the way.

The 40V Samsung Lithium-Ion battery runs for about 2.5 hours per charge and recharges in around an hour with the quick charger supplied. Seven cutting heights range from 25mm to 75mm, all adjusted by a single central lever. A rear roller presses the grass as you mow, leaving a striped finish.

Cut grass collects in a 35 litre hybrid bag fitted with a full level indicator. The handle folds flat for storage and a carry handle makes lifting simple. At 14kg it stays light enough for most people to push around flower beds and tight corners.

Product Features

Brushless Motor with Torque Sense Boost - The motor senses resistance when grass thickens and boosts power automatically. This keeps the blade spinning at a steady speed rather than stalling. Brushless motors run cooler than standard motors and last longer, since there's no brush friction wearing parts down over time. 40V Samsung Lithium-Ion Battery - A 2.5Ah battery gives roughly 2.5 hours of runtime depending on grass length and garden size. It fits other tools in the Yard Force GR40 range, so one battery and charger can work across a mower, strimmer or hedge trimmer, cutting down on spare batteries needed. 7 Cutting Heights - A single lever adjusts cutting height from 25mm to 75mm across seven positions. Shorter grass suits dry weather while taller settings protect the lawn root system in summer heat. Quick adjustment means less time spent fiddling and more time mowing.
Rear Roller - The roller sits behind the cutting deck and flattens grass in alternating directions as you walk up and down. This creates the striped pattern seen on football pitches and bowling greens, giving a tidier finish without extra equipment. 35 Litre Hybrid Grass Bag - The bag combines solid and mesh sections to improve airflow, which compacts clippings and reduces how often it needs emptying. A grass full indicator on top shows when it needs clearing, so you don't lift it open to check manually. Folding Handle - The handle folds down flat, cutting the amount of space the mower takes up in a shed or garage. A separate carry handle on the body makes lifting and moving the folded mower straightforward, even up steps or into a car boot.

FAQs

How long does the battery last on a single charge?

The mower uses a 40V Samsung Lithium-Ion battery with a 2.5Ah capacity. Average runtime sits around 2.5 hours but this depends on grass length and garden size. Many owners report getting 1.5 to 2 full cuts of a medium garden on one charge. One reviewer with a 100m² lawn used only 25-50% of the battery per cut. A full recharge takes about an hour with the quick charger included in the box. Some users have reported battery degradation after several months of use though Yard Force has replaced faulty batteries under warranty in these cases.

What size lawn is this mower suitable for?

This mower is built for small to medium lawns up to roughly 350m². One reviewer confirmed it coped well cutting a sloping 350m² lawn without issue. For larger plots you may want a spare battery on hand so you are not left waiting mid-cut. It handles complex garden shapes and minor slopes thanks to its lightweight 14kg build.

How many cutting height settings does it have?

There are 7 cutting heights ranging from 25mm to 75mm, adjusted using a single central lever. This makes it easy to switch heights without fiddling with each wheel separately. Several reviewers prefer the second or third lowest setting for a close but healthy cut. Cutting shorter and more frequently tends to keep grass greener according to owner feedback.

Is the mower heavy to push around the garden?

At 14kg the mower is light enough for most people to manoeuvre with ease including older users. The dimensions are 140cm deep, 40cm wide and 106cm tall when unfolded. A carry handle is fitted for lifting and moving even when folded. Some owners did find it a bit unwieldy in tight corners so take this into account if your garden has lots of narrow edges or obstacles.

How big is the grass collection bag and how does it work?

The hybrid grass box holds 35 litres and includes a grass full level indicator so you know exactly when to empty it. The hybrid design optimises airflow to compact clippings reducing how often you need to stop and empty it. Reviewers note it collects grass effectively compared to some rival brands and is simple to remove and refit.

Does the mower come assembled or is assembly required?

Some assembly is needed but it is minimal. Mainly you need to attach the folding handle to the main body. Most reviewers completed this in under 30 minutes using basic tools and the included instructions. The handle folds flat afterwards for compact storage making the mower easier to fit in a shed or garage.

What warranty and after-sales support is provided?

Yard Force backs this mower with a 2+1 year manufacturer warranty plus after-sales support available seven days a week. Several reviewers who experienced battery degradation contacted customer service and received replacement batteries within a few weeks. One long-term reviewer went through two replacement batteries and eventually had the whole mower collected for repair or replacement after 22 months, showing the support process works even for repeat issues.

Can the battery be used with other garden tools?

Yes. The battery is part of the Yard Force GR40 range so it is interchangeable with other tools in that range such as hedge trimmers and strimmers. This means you only need to buy one battery and charger set to power multiple garden tools, which several reviewers mentioned as a reason for choosing this mower and planning to expand their Yard Force tool collection.
