The durable AL-KO Highline 42.7 SP petrol lawn mower offers mow, collect, side discharge and mulch functions; a 4-in-1 combination that makes this versatile machine able to tackle a variety of cutting conditions from a well manicured lawn to rougher areas of long grass.

Power is converted to performance by the Briggs & Stratton Series 575 EX engine which delivers a solid 140cc of engine capacity. This engine further enhances the mowing experience thanks to the overhead valve technology for reduced emissions and greater fuel economy, Super Lo-Tone™ muffler for quieter operation, and a Magnetron® electronic ignition for reliable starting every time.

The AL-KO Highline 42.7 SP features a self-propelled transmission to make mowing on slopes less of an effort, and extra large wheels with wide tyres for protection of the lawn and improved comfort and traction when encountering uneven ground.

A 46cm (18") MAX AIRFLOW deep steel deck optimises aerodynamics beneath the deck, which results in equally efficient and effective performance in each of the four cutting modes. The cutting height can be conveniently adjusted through seven stages between 30mm and 80mm via just one spring-assisted lever. The bag full indicator on top of the 70 litre collector will let you know when it requires emptying.

Featuring folding handles, the mower has an integrated storage function whereby the machine can be stood on its end for space-saving storage and easy access to the underside of the deck for cleaning and maintenance.

Complete with the reassurance of German-engineering and Austrian manufacture, backed by a five year warranty, the AL-KO Highline 42.7 SP self-propelled petrol lawn mower is a great choice for areas up to 1400 square metres.

Briggs & Stratton Engine

The 575EX Series provides the best-in-class performance in this category of engines, incorporating the latest engine design technologies ensuring optimal torque and efficiency, resulting in lower emissions.

OHV Technology

OHV technology for more performance, less consumption through optimal valve location and design of chamber.


The mower is equipped with a clutch which, when engaged, propels the mower forward, reducing the amount of effort expended by the operator.

4-IN-ONE Function

A multi-function machine, AL-KO's prized 4-in-1 function features collect and mulch, plus side and rear discharge capabilities.
AL-KO Highline MaxAirflow technology


Extra tall, extra large – that's the basis for MaxAirflow technology. This is because the extra tall steel plate deck and extra large discharge channel increase the airflow by 42 per cent. As a result, the grass clippings are not transported at a low level into the grass catcher as in the case of most standard lawnmowers, but are instead thrown backwards in a high arc and remain at the back. This means the grass catcher is effectively filled from the back, without the discharge channel becoming blocked. Another bonus: The removable service flap for convenient mower maintenance.

Full Catcher, Fewer Interruptions

MaxAirflow technology means that the lawn clippings are thrown to the back of the grass catcher, as a result of which it is filled to the top and does not have to be emptied so often.

No Green Fingers

MaxAirflow technology means that it is even possible to mow long, damp grass without leaving clumps behind on the ground or blocking the discharge channel. This means your hands stay cleaner.
