Buying second-hand

Used-market tip

£200–340 used. Confirm 36V battery is genuine Ryobi MAX (counterfeits are common). 5Ah battery healthy runtime is 35–45 minutes. Self-propel drive belt is the wear part — listen for slip under load.

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.
