Webb Review UK 2026
Quick verdict
Score: 7.5/10
Best for: Keeping your lawn tidy to suit its size and terrain
Not for: A lawn much bigger or rougher than this mower is built for
Bottom line: A capable lawn mower (petrol mower, 46cm cutting width, 141cc petrol engine) for a well-kept lawn.
Often, a mower's headline specs determine who it suits best. The Webb WER460SP is built around a petrol 141cc engine with a 46cm cutting width, and this lawn mower review UK frames it as a conventional petrol lawn mower for regular yard mowing. The 46cm cut covers ground efficiently, while self-propelled rotary action reduces pushing effort, but it is less suited to very small, tight-area trimming because the 55L grass bag can require frequent stops.

Mower Type and Power
The Webb is a self-propelled rotary petrol lawn mower, powered by a 141cc petrol engine that drives the cutting action across a 46cm swath each pass. This mower type is designed for situations where the machine can be guided rather than fully pushed, which can help on uneven or longer grass, while maintaining a consistent rotary cut through typical growth when the fuel supply is managed. The 141cc power level positions it as a mid-range option for average garden lawns, though dense weed patches may still require extra passes. Maintenance is based on standard petrol upkeep, rather than battery charging.
Cutting Width and Deck
Cutting width is a key practical factor on the lawn mower, because it is rated for a 46cm swath each pass. This width influences how quickly an area can be covered, since a wider deck typically means fewer overlapping passes. The mower uses a rotary cutting system with a deck sized to match that 18-inch/46cm figure, and it offers 7 cutting heights so grass can be adjusted for different lawn conditions. During mowing, the operator should follow steady lines and overlap slightly at edges to maintain consistent coverage. Deck performance on uneven ground depends on the terrain and the mowing-height choice.
Lawn Size and Collection
Lawn-size suitability is closely tied to the Webb's 46cm cutting width, because this width determines how much area is covered with each pass. For larger lawns, it can reduce the number of passes compared with smaller-deck models, although the pace also depends on mowing pattern and grass thickness. A 55L bag can help during longer sessions, and once full it must be emptied. Cutting heights are available at seven settings, which makes uneven lawns easier to manage.
Ease of Use and Storage
Using the lawn mower is fairly straightforward because it is a self-propelled rotary petrol mower with a 46 cm cutting width, and it can cover turf efficiently without requiring constant pushing. For convenience, it uses seven cutting height settings, so the user can adjust for different grass conditions before mowing, then lock the chosen height in place. For storage, the 46 cm deck and grass box mean it needs a garage, shed, or corner with enough space for the mower and the 55 L bag.
Who Is This Lawn Mower For?
For many UK gardens, the Webb WER460SP suits people who want a petrol-powered, self-propelled lawn mower that can cut grass regularly without constant pushing. The 141cc petrol engine and 46cm cutting width make it practical for medium-sized lawns, where a wider pass reduces overlap. The mower includes grass box collection, which suits users who prefer bagging. Seven cutting heights allow adjustments for different lawn conditions, from shorter growth to longer grass. It may be less suitable for very small spaces, where storage and manoeuvring can feel tight.

Frequently Asked Questions
Is the lawn mower worth it?
For keeping a lawn tidy with the least hassle, this lawn mower (a petrol mower) does the job with a 46cm 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 Webb?
The Webb WER460SP is a petrol 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 46cm 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.
How powerful is the Webb?
The lawn mower runs on a 141cc petrol engine. Petrol engines give strong, sustained cutting power for long grass and large lawns.
Is the Webb self-propelled?
Yes - the lawn mower is self-propelled, so it drives itself forward and you simply steer. That's a real help on larger lawns or any slope, saving you pushing the full weight of the mower. On small flat lawns a push mower is fine and lighter.
Does the Webb WER460SP 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 Webb 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.
