Built to Mountfield’s consistently high standards and offering numerous quality features and high-performance cutting, the powerful Mountfield SP51H Petrol Lawnmower is one of the best-value machines in its class!That power is supplied by a Honda GCVx145 engine; a pro-grade air-cooled four-stroke unit with an OHV formation for emission compliance, vibration- and noise-reduction, and improved fuel-economy.Honda’s intelligent Auto Choke Comfort System (ACS) ensures ultra-reliable ignition under all conditions; while their high-specification Combustion Technology works to optimise power output, with the engine producing a substantial 4.2hp from a displacement of just 145cc.The Mountfield SP51H Petrol Lawnmower has been equipped with self-propulsion, so will prove a real boon if your lawn’s on a slope, or has sections of rough, bumpy grass.Centralised height-of-cut adjustment makes what can be a troublesome process with lesser machines an easy one; larger-diameter drive-wheels provide superior manoeuvrability, especially when working on long grass.Supplied with mulch plug, a large 60-litre-capacity collector and a discharge chute, the Mountfield SP51H is capable of either bagging, recycling or rear-discharging your grass cuttings (the catcher has a dust- and pollen-retaining hard plastic top, and is made from canvas to save storage space).The chassis on the Mountfield SP51H 3-in-1 Self-Propelled Petrol Lawnmower benefits from a powder-coated paint finish that’s both corrosion- and scratch-resistant.Designed to perform quickly and efficiently across substantial areas, this model has an expansive 51cm working-width.
