Product Information

The Comfort 51.0 SP-A self propelled petrol mower from AL-KO features a 20 inch/51cm cutting width. single speed power drive and is powered by the AL-KO Pro 145 engine. Fitted with the taller MaxAirFlow steel cutting deck that improves grass collection and helps prevent the discharge channel from becoming blocked. 

4 in 1 mowing functions give the user the choice between cut and collect. rear discharge. side discharge and mulching. Cut and collect the clippings into the EasyClick 60 litre box with fill indicator to let you know when it requires emptying. Rear discharge allows the clipping to be ejected from the rear of the mower. leaving them to wilt back naturally. Side discharge ejects the cutting from the side of the mower. leaving them in neat rows whilst you mow. The mulching option is particularly beneficial during the hotter. drier months as the tiny clippings provide additional moisture and nutrients to the lawn. promoting healthier regrowth. 

7 cutting heights ranging through 30-80mm that can be easily adjusted with the spring assisted central lever. Start with the highest setting and work your way down to get the best cut and finish to your lawn. 


  • 60 litre Easy Click rigid grass collector designed for optimum airflow which improves the filling performance. The collector can be re-attached easier with a guide rail. Fill level indicator to alert the user when the collector is full.
  • MAXAIRFLOW Steel Deck: The deeper cutting deck with larger discharge channel increases the airflow so the grass cuttings are thrown higher to the back of the grass box. The box can then be filled to the top and the discharge channel doesn’t get blocked.
  • 4INONE Function: Mow. collect. side discharge and mulch
