Product Information:

The AL-KO Comfort 51.0 SP-A self-propelled lawn mower has a 20 inch / 51cm cutting width, single speed power drive and is powered by the AL-KO Pro 145 engine. The taller MaxAirFlow steel cutting decks fitted to these Comfort 51.0 models will improve grass collection and help to prevent the discharge channel from becoming blocked. The Comfort 51.0SP-A 4 wheel lawnmower has a 4-in-1 mowing function which gives the user the choice between collect, rear discharge, side discharge and mulch. The grass is collected into an EasyClick 60L box which has a fill-level indicator to let you know when it requires emptying. Changing the cutting height couldn’t be easier with the spring assisted central lever. The lever can be set through 7 adjustments from 30 – 80mm. Start with the highest setting, then work down gradually to achieve the best cut and finish for your lawn. If you don’t want to just cut & collect the grass you can choose between discharging it to the rear of the mower, discharging it to the side in a neat line or mulching it into fine pieces. The rear or side discharge functions are especially good when mowing informal or long grass areas where the cuttings can be left to wilt back naturally. Mulching is an excellent way to feed the lawn as the tiny grass pieces are rich in nutrients and as they wilt will release these back into the soil. Mulching is recommended in drier conditions and when the grass is shorter. The pieces are so small they virtually disappear into lawn whilst you’re mowing. Features

  • Which Best Buy Lawnmower 2021
  • 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
  • Wide XXL rear wheels (280mm) with double ball bearings ensure easy manoeuvrability
  • Integrated front carry handle so the mower can be easily moved and transported
