The modern design makes it an eye-catcher in all gardens. The lawn mowers in the "Comfort" series make lawn mowing a pleasure.


Technical Details of The Comfort 51.0 SP-A Petrol Mower

With a wide cutting width of 51 cm, the Comfort 51.0 SP-A self-propelled petrol lawn mower ensures great efficiency in medium and large sized gardens (up to 1800 m²). The cutting height is adjusted centrally in up to 7 stages ranging from 30 mm to 80 mm. The power is provided by an easy starting AL-KO PRO 145 QSS engine which enables you to mow effectively in even the most demanding of conditions. The wheel drive function is particularly useful in gardens with slopes whilst the XXL ball bearing wheels ensure smooth rolling across the lawn. The 4IN1function offers great versatility providing mowing, collection, mulching and side discharge options making this suitable for use in a wide range of mowing conditions. The ergonomically shaped handlebar with strong rubber grip ensures increased comfort when working. Thanks to the extra deep sheet steel mower deck with MaxAirflow technology, the grass clippings are blown to the back of the 70 litre plastic grass collection box which means that it is filled effectively and therefore has to be emptied less often. The integrated fill level indicator grass shows the user when the box is full to capacity and requires emptying therefore eliminating the need to stop mowing to check.
