The highest specification lawn mower in the AL-KO Easy range, the 5.1 SP-S boasts excellent build quality and superior German design, backed by an industry-leading five year manufacturer's warranty.

The AL-KO Easy 5.1 SP-S is equipped with a rugged multi-function 51cm (20") steel deck which gives you the flexibility to choose between the four modes of mowing, collecting, mulching and side discharge. The mower has a spacious 60 litre grass collector which cuts down-time by reducing the frequency of emptying. The central seven-stage cutting height adjustment allows you to deal with varying mowing conditions.

The engine is a Tech 165, which is AL-KO's own four-stroke, air-cooled motor employing overhead valve technology for long service life, improved fuel economy and a considerable reduction in noise, vibration and emissions. Effortless self-propulsion and the XXL rear wheels will give smooth and gentle progress with excellent grip, even over rougher grassed areas and gently sloping lawns.

The ergonomically-shaped handlebar maximises user comfort. The folding handlebar and integrated front carry handle combine to enable easy transportation and compact storage.

The AL-KO Easy 5.1 SP-S self-propelled lawn mower is a great value for money choice for lawns up to 1800 square metres.
