Yard Force LM C33 20V Cordless Lawnmower (33cm, 4.0Ah)

What size lawn is this mower designed for?

The Yard Force Cordless Lawnmower is built for lawns up to 200m². That covers most small and medium gardens. Its 33cm cutting width makes it easy to manage borders and tight corners. Will one charge get you round a full 200m² plot? Usually yes but it depends on grass thickness. The 20V battery gives roughly 25 minutes of run time. For bigger gardens you might need a second pass or a spare battery on hand.

How long does the battery take to charge and how long does it run?

A full charge takes 100 minutes. Run time averages 25 minutes per charge depending on how thick your grass is. The lithium-ion battery has no memory effect, so you can top it up whenever you like without shortening its life. You don't need to wait for it to run flat first. Some owners who mow larger areas keep a spare 4.0Ah or 5.0Ah pack charged and ready.

What cutting heights does it offer?

There are five height settings ranging from 20mm to 60mm. A single lever changes the height so there's no need for tools. Want a close tidy cut? Use the lowest setting. Prefer to leave grass a bit longer for drought resistance? Go higher. The steel blade keeps a consistent 33cm cutting width across every position.

How much does the mower weigh and does it fold for storage?

This mower weighs 8.6kg, which is light compared to most petrol models. Assembled dimensions are 40cm deep, 33.5cm wide and 61cm high. The handle folds down flat so it fits into tight spaces like shed shelves or garage corners. Several buyers mention the folding handle as a main reason they picked this Cordless Lawnmower over a bulkier alternative.

What size is the grass collection box and how does it work?

It comes with a 30 litre hybrid grass collection bag. The bag has a full level indicator so you know exactly when to empty it. Why hybrid? It allows free airflow through the bag while also compacting clippings inside. That means fewer trips back and forth to the compost bin and longer stretches of mowing between empties.

Can it cope with long or wet grass?

This is where feedback is mixed. Several reviewers found it struggles once grass gets past a couple of inches or when it's damp. The motor is brushless and efficient, but power is limited by the 20V battery setup. It performs best on lawns mown regularly and kept short. If your grass has grown out, going over it twice usually sorts it, though strimming first can help in tougher patches.

What warranty and support come with the mower?

Yard Force backs this mower with a 2+1 year manufacturer warranty. That's two years standard plus a third year once you register the product. Customer support runs seven days a week. One buyer had a faulty battery replaced free of charge with no fuss, which says a lot about the after sales service behind it.

What battery options are available and what's the difference?

Four configurations are sold: a single 4.0Ah battery, a single 5.0Ah battery, or twin packs of either 2.5Ah or 4.0Ah. All run at 20V. A single 4.0Ah pack gives the standard 25 minute run time mentioned above. Why pick twin batteries? You can swap one out while the other charges, handy for bigger lawns or longer mowing sessions without a break.
