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 51.0 SP-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.


Self Propelled Wheel Drive

The wheel drive function enables the mower to be operated easily even on slopes

Wide XXL wheels.

The XXL wheels with double ball bearings enables the mower to be pushed smoothly across grass or uneven land



The 4INONE function allows the user to mow, collect, mulch and side discharge all from a single machine for maximum durability.
