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.

Your advantages

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.

It's a matter of height
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 percent. 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.
Easy to fit Grass Collector
Thanks to the integrated lip on the collector, it can be easily mounted to the mower.
