Mowing the lawn with the AL-KO 42.7 SP-A Highline petrol lawn mower is no sweat thanks to the single speed wheel drive which enables the mower to propel itself along rather than requiring the effort of pushing. Providing the power to the machine is a 123cc AL-KO 125 Pro four-stroke, air-cooled engine with OHV technology for reduced fuel costs and carbon emissions, as well as low noise and vibration.

Equipped with a robust 42cm (16") ULTRAMOW steel deck, this four-wheel rotary lawn mower is suitable for lawns up to 1,000 square metres in size. AL-KO's 3-in-one function offers collection, rear discharge and mulching capabilities, all in one flexible machine. The comfortable three lever cutting height adjustment enables the mower to cut at seven different heights from 25mm to 75mm.

In the increasingly popular mulching mode and fitted with the mulch plug provided, the grass clippings are prevented from being discarded through the discharge channel so they are retained in the deck and chopped extremely finely. These tiny cuttings are then dispersed evenly on the ground to provide natural fertiliser which, when done regularly, can enhance the health of your lawn.

The spacious 65 litre grass collector features a bag full indicator which makes the user aware when the collector is filled to maximum capacity and requires emptying, preventing the discharge channel from becoming blocked.

The AL-KO Highline 42.7 SP-A has large 220mm rear wheels that help manoeuvrability and make it easier working in long grass. All four wheels are mounted on ball bearings for a smooth drive, even on rougher ground.

When not in use, AL-KO's ingenious storage position allows the mower to be stood vertically for space-saving storage and easy access to the cutter deck for cleaning and maintenance.

Designed in Germany and built in Austria, the AL-KO Highline 42.7 SP-A is a well equipped petrol rotary lawn mower backed by a conditional five year manufacturer's warranty.
