Allett makes cassette-based cylinder mowers out of Warwickshire, England, and they’re the mower a lot of greenkeepers end up buying for their own lawns once they’ve used one professionally. That reputation shows up in the price. A battery Allett is not a casual purchase, and it’s worth knowing exactly what you’re paying for before you commit.
What battery Allett mowers actually cost
Allett’s battery range sits under the Liberty name, built around their 43cm and 53cm cutting widths. Street prices in the UK typically run from around £900 for a basic Liberty 43 with a single cassette, up past £1,600 once you add a second cassette (like a scarifier or verticutter head) and a second battery. The 53cm Liberty models, aimed at bigger lawns, land higher again, often £1,400 to £1,900 depending on battery count and which cassettes are bundled.
That’s before you’ve bought anything extra. A spare battery alone can run £200-£300, and additional cassette heads (slitter, scarifier, brush) are typically £150-£250 each. People who buy into the Allett system properly, with two or three cassettes and a spare battery, often end up spending close to double the base mower price over their first year of ownership.
For comparison, a petrol cylinder mower from Allett’s own range (the Classic or Kensington lines) can be cheaper to buy outright but costs more to run over time in fuel, servicing, and oil changes. The battery premium buys you quiet operation and zero exhaust fumes, which matters if you’re mowing a small lawn near the house or doing it on a Sunday morning without annoying neighbours.
Why Allett costs what it costs
The cassette system is the actual innovation here, not just marketing. Instead of buying a whole new mower to scarify or verticut your lawn, you swap the cutting cylinder for a different cassette on the same power base. That’s genuinely useful if you take lawn care seriously, because a decent scarifier bought separately costs £300-£500 on its own. Spread across three or four cassettes, the base unit cost starts to look more reasonable.
The cylinders themselves are also better made than what you get on budget cylinder mowers. Allett uses hardened steel blades set to a tighter tolerance against the bottom blade, which is what gives cylinder mowers their clean, striped finish in the first place. Cheap cylinder mowers lose this edge within a season or two; Allett’s hold it longer and are designed to be re-ground rather than replaced.
Build quality aside, you’re also paying for a brand with 100+ years of history supplying sports turf equipment, and a dealer network that actually stocks spare parts and blades. That matters more than it sounds. Cheap cylinder mowers from unknown brands often become unrepairable within a few years because nobody stocks the parts.
How it compares to other cylinder mowers
| Mower type | Typical price | Best for | Main trade-off |
|---|---|---|---|
| Budget electric cylinder mower | £150-£300 | Small, flat lawns under 150m² | Blades dull fast, no cassette system, short motor life |
| Mid-range petrol cylinder mower | £400-£700 | Lawns wanting stripes without battery cost | Noise, fuel, servicing, no quick-swap heads |
| Allett Liberty (battery) | £900-£1,900 | Lawn enthusiasts wanting stripes plus scarifying/verticutting | High upfront cost, extra cassettes add up fast |
| Rotary mower (battery) | £200-£600 | Uneven lawns, general tidiness over stripes | No true cylinder stripe finish, less precise cut height |
If stripes aren’t the point and you just want the lawn cut, a battery rotary does the job for a fraction of the price and copes better with longer grass and bumpy ground, where cylinder mowers struggle. Browse battery rotary mowers if that’s closer to what you actually need.
Who should actually buy one
The Allett battery range makes sense for a specific person: someone with a lawn in the 100-400m² range who already cares about stripe quality and wants to scarify or verticut without buying separate machines. If your lawn is bumpy, has tree roots, or runs to moss and weeds rather than fine grass, a cylinder mower of any brand will struggle and you’re better off with a rotary.
If you’re mowing a lawn under 100m² and just want it neat, spending £900+ is hard to justify. A decent electric cylinder mower in the £150-£300 range will give you a passable stripe for a couple of seasons, and by the time the blades dull you’ll know whether you actually want to upgrade into the Allett system or whether rotary mowing suits you fine.
For bigger gardens, battery runtime is the real constraint to check before buying. Allett’s battery decks typically run 30-45 minutes per charge depending on grass length and cassette fitted, which covers a few hundred square metres comfortably but means a second battery isn’t optional on larger plots, it’s part of the real cost of ownership.
What to check before buying
Ask any dealer whether the price quoted includes one cassette or more, and whether a second battery is bundled, since listings vary a lot on this. Check blade count on the cylinder (more blades per cassette gives a finer stripe but costs more to re-grind) and confirm local servicing is available, since Allett cylinders need re-sharpening every one to two seasons depending on use. If you’re buying secondhand, inspect the cylinder for nicks and check the bottom blade adjustment, since a worn one needs replacing before the mower cuts cleanly again, and that’s not a cheap fix on a machine this specialised.
