Mower Type and Power
Mower Type and Power for this lawn mower (model 11765-20) is a cordless, manual push cylinder mower. There is no engine, battery runtime, or cable management, because cylinder action is driven by the user's pushing force, turning the grass blades as it moves. For small-to-medium gardens, this can be a practical approach, though it requires more physical effort than powered options on larger or tougher patches.
Cutting Width and Deck
With a 40 cm cutting width, the Gardena is designed to cut a wider strip of grass with each pass, which can help reduce the total mowing time for lawns up to 250 m². The deck size aligns with this wider sweep, so straight overlapping strokes are less necessary than on narrower mowers. When mowing, push in straight lines and make a slightly offset second pass to help pick up any edges. On uneven ground or thicker patches, keeping a consistent pushing speed helps support a more even cut, as manual push force affects how uniformly the grass is processed.
Lawn Size and Collection
For lawns up to 250 m², the lawn mower is sized for typical home gardens, where repeated passes can be made without needing to manage a power cable or battery charging routine, since it is cordless. With a 40 cm cutting width, it covers each strip steadily, then advances row by row until the full area is handled. Collection is managed by a grass box, allowing clippings to be collected during mowing rather than being left loose. For lawns larger than 250 m², mowing time requirements and collection emptying frequency are not stated.
Ease of Use and Storage
Ease of use and storage for the Gardena is shaped by its manual, cordless design and its grass box. With a 40 cm cutting width and a grass box collection, the operator pushes the mower steadily and stops to empty the box when it fills. Because it is cordless, there is no need to manage cables or batteries during use, which keeps setup simple. For storage, the compact manual format generally requires less clearance than powered mowers, although the mower still takes up space on the floor due to its cutting width. The grass box can be awkward to clean if clippings stick, so regular emptying helps keep it ready for the next mow.
Who Is This Lawn Mower For?
This manual push lawnmower is aimed at people who want a simple, cordless way to cut relatively small lawn areas. It is positioned for lawns up to 250 m², where repeated pushing stays practical and the workload remains manageable. The 40 cm cutting width suits homeowners who prefer steady, straight passes rather than frequent overlap. It also fits users who want grass box collection, since clippings are gathered during mowing instead of being left to spread. For larger gardens or for anyone needing to cover turf quickly, it may be slower, as the specifications do not indicate high-capacity performance.
Where to Buy in the UK
The lawn mower (11765-20) is aimed at UK buyers with smaller lawns, and it is typically available through common home-and-garden retail channels as well as online listings. Shoppers can check major garden centres and hardware stores, then compare what is in stock with the mower's 40 cm cutting width and suitability for lawns up to 250 m². Online, it is often listed by garden equipment retailers and marketplace sellers, so buyers should confirm the model code 11765-20 and that a grass box is included. If any detail is missing, they should request clarification before purchase.
Frequently Asked Questions
Is the Gardena Manual Push Lawnmower worth it?
For keeping a lawn tidy with the least hassle, the Gardena (a cordless mower) does the job with a 40cm 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 lawn mower?
The Gardena 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 the lawn mower?
This lawn mower has a 40cm 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 Gardena cover?
The Gardena Manual Push Lawnmower is rated for up to 250m² 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.
Does the lawn mower collect or mulch the grass?
This lawn mower 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 Gardena 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 lawn mower 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.
