Mower Type and Power
A cordless mower is what this lawn mower is, running on a 40V battery system rather than mains power. It is designed for lawn mowing without extension leads, which can make it simpler to move around the garden. Power is provided by the included 40V batteries, and the mower is intended to handle lawns up to 400m², according to the product listing. Because battery tools depend on charge level, longer mowing sessions may require planning for larger areas. Quick start convenience is likely to be a benefit.
Cutting Width and Deck
Cutting width is one of the main ways this mower affects how efficiently it moves through the lawn, and the Greenworks is rated at a 35 cm cutting width. With a deck sized to match that width, each pass covers a moderate strip of grass, so mowing faster usually comes from steady, straight overlapping strokes. A 35 cm deck works well in smaller or tighter areas where turning space matters, but it may take more passes than wider models on open ground. Deck performance also depends on technique, so uneven patches need slower movement to keep the cut consistent.
Lawn Size and Collection
For lawn sizing, the lawn mower cordless lawnmower (G40LM35K2X) is described for lawns up to 400m², setting expectations for how much grass it can handle in one session before collection becomes an issue. The 35cm cutting width covers a strip per pass, so larger areas require more overlapping passes to finish edging cleanly. Grass collection is handled by a 40L bag, so fuller-bag stops are more likely during longer, heavier grass collections. On small to mid-sized lawns, bagging suits routine maintenance, while very heavy clippings may require more frequent emptying.
Ease of Use and Storage
Ease of use and storage matter because the Greenworks is designed for regular lawn upkeep rather than long, complex setup sessions. It is cordless, with a 40V battery powering a 35cm cutting width, which avoids cable management. The mower's compact mowing size helps it fit in a shed or garage, and the grass box collects clippings to reduce mess when the box is emptied. Two 40V 2Ah batteries can simplify switching, though storage space is still needed for the batteries and the charger. Operation feels straightforward, with minor routine steps before each use.
Who Is This Lawn Mower For?
This mower suits people who want a cordless 40V lawn cut without dealing with a cable, particularly for lawns up to 400m². The 35cm cutting width is set up for regular garden maintenance rather than clearing very large plots, so heavier or overgrown lawns may need multiple passes. It is also aimed at households that prefer grass collection via a grass box, helping keep clippings tidier during routine mowing. Two 40V 2Ah batteries and one charger are included, making it a practical option for anyone storing a matching battery-powered tool set.

Frequently Asked Questions
Is the Greenworks worth it?
For keeping a lawn tidy with the least hassle, the lawn mower (a cordless mower) does the job with a 35cm cutting width. Whether it suits you comes down to your lawn size, terrain and how much effort you want to put in. Check the current Amazon UK price, as mowers are often discounted in season.
What type of mower is the Greenworks?
The lawn mower is a cordless mower. Petrol mowers are powerful and cordless for big or rough lawns; cordless battery mowers are quiet and low-maintenance for most gardens; corded electric are light and cheap for small lawns; hover mowers glide for edges and slopes; manual push mowers are eco and silent for tiny lawns. Choose the type for your lawn size and terrain.
What is the cutting width of this lawn mower?
The Greenworks has a 35cm cutting width. A wider deck cuts more grass per pass so you finish faster - better for bigger lawns; a narrower deck is lighter and more manoeuvrable around borders and obstacles. Match the width to your lawn size and how tight the spaces are.
What lawn size does the Greenworks G40LM35K2X cover?
The lawn mower is rated for up to 400m² working area. With robotic mowers it's important the working area comfortably exceeds your actual lawn, allowing for shape and slope. If your garden is close to the limit, size up to a model rated for a larger area.
How powerful is this lawn mower?
The Greenworks runs on a 40V battery. Higher battery voltage generally means more cutting power and run time; check the battery is included, as some are sold as bare tools.
Does the lawn mower collect or mulch the grass?
The Greenworks collects clippings into a grass box as you mow, so you get a clean finish and simply empty it when full. Check the grass box capacity against your lawn size to avoid frequent stops.
Is the lawn mower easy to store?
Storage depends on the design - many electric and cordless mowers fold or stand upright to save space, while petrol and ride-on mowers need more room. The Greenworks G40LM35K2X is a typical example for its type; if space is tight, look for a compact-fold or upright-storage model like Flymo's EasiStore range.
