The German company AL-KO manufactures two 51cm petrol lawnmowers that have been named ‘Best Buy‘ by Which? magazine according to the badges displayed on the images on their web site.
The AL-KO Petrol Lawnmower Highline 523 VS was awarded a Which? Best Buy in a March 2014 review.
The AL-KO 523 VS is fitted with a 190cc Briggs and Stratton 675EX Series petrol motor. I has a single lever height adjuster with seven steps ranging from 30mm to 80mm. As well as catching the mown grass in a 70 litre collector you have the options to mulch or side discharge.
The Al-Ko 523-VS Highline 4-in-1 Petrol Lawnmower is available on-line from MowDirect.
The other AL-KO 51cm (20″) Which? Best Buy was given that title back in October 2011 but is still available. It is the AL-KO Silver 520 BR Premium petrol lawnmower.
The Al-Ko 520BR Premium 4-in-1 Petrol Power Driven Lawnmower has a fairly similar specification to the Al-Ko 523-VS Highline and is also available from MowDirect.
