Product Information:

AL-KO Premium petrol lawn mowers are top of the range machines with superior features and a high technical . These models are available with a Briggs & Stratton or Honda variable speed drive.The ALKO Premium 521 VS-H power drive lawn mower has a 51cm (20") cutting width, variable speed control and Honda GCVx170 engine. A deep MaxAirFlow steel cutter deck improves grass collection and helps to reduce any blockages in the discharge channel.The Premium 521 VSH four wheel lawnmower uses a 4-in-1 mowing function which gives the user the choice between collect, rear discharge, side discharge and mulch. Grass clippings are collected into an EasyClick 70L box which has a fill-level indicator to let you know when it needs emptying. Adjusting cutting heights is simple with the spring assisted central lever. The lever can be set through 7 positions from 30 – 80mm. Start with the top setting then work down gradually to achieve the best cut and finest finish on the lawn.If you don’t want to just cut and collect the grass you can change 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 designed for mowing informal and long grass areas where any 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 for drier conditions and when the grass is shorter. The pieces are so small they virtually disappear into lawn whilst you’re mowing.Features

  • 70 litre Easy Click rigid grass collector designed for optimum airflow improving 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: A deeper cutter deck with larger discharge channel increases the airflow so the grass clippings can be thrown higher, right to the back of the grass box. The box can then be filled to the top more effectively and the discharge channel doesn’t get blocked.
  • Variable speed control: Adapt the travelling speed of the mower for the most comfortable working pace.
  • Ergonomic handles with the controls at your fingertips.
  • Integrated front handle so the mower is easy to lift over obstacles.
  • 4INONE Function: Mow, collect, side discharge and mulch
  • Wide XXL rear wheels (280mm) with double ball bearings ensure easy manoeuvrability
