Our verdict
The bottom line
For people who care about their lawn the way bowling-green groundsmen do. The Allett Liberty is what the Suffolk Punch wishes it were — modern, cordless, and with interchangeable cassettes that turn it into a scarifier. A specialist tool for a specialist lawn. If that's you, nothing else competes.

Buying second-hand
Used-market tip
£600–1000 used. Cylinder sharpness is non-negotiable — test cut paper. Allett re-grind service exists at their factory; £80 turnaround. Confirm cassette set is complete (cylinder is mandatory; scarifier and brush are optional but valuable). Reset Allett account if app-connected.
Where to look: Facebook Marketplace and Gumtree are usually 20–30% cheaper than eBay UK for petrol mowers because most sellers want local pickup. eBay tends to win on cordless and electric (lighter, easier to ship). Always insist on a starting demonstration before paying.
