ATCO Quattro 16S 41cm Self-Propelled Petrol Lawn Mower
The Quattro 16S is ATCO's entry point into the self-propelled range and it's a well-rounded machine for what it is — a compact, manoeuvrable mower for smaller gardens that doesn't make compromises on versatility. The four-wheel design with rear-wheel drive handles uneven ground and gentle slopes more confidently than a two-wheel-drive machine, and at 41cm cutting width it fits comfortably through standard garden gates and into tighter spaces without losing the ability to cover a 400m² lawn in a reasonable time.
The Stiga ST 140 OHV engine with automatic choke keeps starting simple — no priming, no choke adjustment, just pull and go. The overhead valve design improves fuel economy and reduces emissions compared to side-valve engines, and the autochoke system removes the one step that catches people out on cold mornings. Being self-propelled means the operator controls pace rather than pushing the machine, which makes a meaningful difference on slopes and longer sessions.
Four cutting modes in a single machine at this price point is genuinely useful — collecting for a tidy finish, mulching to return nitrogen-rich clippings to the lawn as natural fertiliser, rear discharge for longer grass, and side discharge for overgrown areas. The mulching plug is included in the box. The 60-litre collapsible textile grass box has a full indicator so you know when to empty it without having to check, and the quick-connect washing link makes cleaning the deck straightforward after use.
Two handlebar height settings accommodate different operator heights, and the single-lever cutting height adjustment covers six positions from 22mm to 65mm. A 5-year manufacturer's warranty is included.
