Along with the usual mowing and collecting functionalities, the added benefits of mulching, side and rear discharge options make this Honda-powered petrol lawn mower as versatile and durable as a mower can be for use in various types of mowing conditions.

The AL-KO Highline 46.7 SP-H, which is suitable for medium to large sized lawns up to 1,400 square metres, draws its power from a legendary 160cc Honda GCV 160 four-stroke engine. The machine is easy to fire up thanks to the automatic mechanical decompression system which opens up the exhaust valve on ignition, resulting in reduced resistance in the recoil starter mechanism. Once on the move, the self-propelled capability means little to no pushing effort on your behalf, so the machine is well suited to lawns on an incline and those with rougher, uneven terrain. The XXL drive wheels further maximise manoeuvrability in long grass by providing better traction.

Equipped with a 46cm (18") steel cutting deck, AL-KO's MAX AIRFLOW deep-dome design increases its efficacy in all four mowing modes by 42%, and fills the large 70 litre grass collector to maximum capacity without blocking the large discharge channel. When the grass collection box does need emptying, the integrated bag full indicator will let you know.

The central height adjustment on the AL-KO 46.7 SP-H allows you to adjust the cutting height easily with just one spring-assisted lever, to give a range between 30mm and 80mm through seven pre-set stages.

As with all lawn mowers in the Highline range, the storage, cleaning and maintenance of the mower's cutter deck are all facilitated by AL-KO's clever vertical storage position.

Honda GCV160 engine

Honda Engine

The GCV 160 engine is a world-renowned power unit, which is incredibly reliable and fuel efficient, while also being very quiet running and easy to start.

AL-KO overhead camshaft 

Overhead Camshaft (OHC) Engine

Overhead Camshaft engines (OHC) are similar to OHV engines, but they also have their camshafts positioned in the cylinder head above the combustion chamber. This means they offer all the benefits of an OHV design and more.

The OHC layout reduces the number of valve train components, which allows them to be lighter and stronger.  This makes the engine more compact and lightweight overall.

Honda’s OHC design offers additional advantages:

  • By combining unique rocker arms and a single camshaft, the cam pulley is located on the side of the cylinder head.  This allows overall engine height to be reduced in comparison to a conventional OHC engine.
  • The efficient Honda OHC mechanism uses a timing belt in oil configuration combined with governor and connecting rod slinger paddles.  This unique DuaLube™ System efficiently and effectively delivers oil throughout the engine.


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

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.

AL-KO mower efficient controls

Efficient Controls

The Highline lawn mower range features efficient controls including a sculpted drive lever to avoid trapping fingers.
