The AL-KO Highline 51.7 SP-H is a 51cm / 20 inch self-propelled lawnmower with the 4 in one function, powered by a realiable Honda engine

The 70 litre EasyClick collector box with optimum aerodynamic airflow combines with the new, deeper MaxAirflow cutter deck ensuring maximum collection and box filling performance. The extra tall steel decks and large discharge channel increase the airflow resulting in grass clippings being thrown in a high arc to the back of the collector ensuring the collector is filled to the top and discharge channel does not get blocked.

The 4 in one function allows you to choose from mowing, collecting, mulching and side discharge all from a single machine. The grass clippings are collected to a very large 70 litre grass box. When selecting the mulching function, the grass clippings are cut once, then once again in tiny pieces, these tiny pieces are then disposed back into the lawn, which acts as a natural fertiliser. The cutting height can be easily adjusted with just one spring assisted lever enabling the lawn to be cut between 30-80mm.

The XXL wheels with double ball bearings enables the mower to be pushed smoothly across grass or uneven land. This lawn mower can be stood vertically to help with under deck cleaning and to save space whilst they are stored away thanks to the integrated storage function. 


Complete with a 5 year homeowner warranty.
