  • 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.

  • Ergonomic handles with the controls at your fingertips.
  • Integrated front handle so the mower is easy to lift over obstacles.

The Premium 521 VS-H variable speed 4 in 1 mower is a top of the range model from AL-KO, with superior features and a high technical specification.

With a 51cm (20 inch) cutting width and powered by a reliable Honda GCVx170 engine with variable speed control. The deep MaxAirFlow steel cutter deck improves grass collection and helps prevent the discharge channel from getting blocked.

4 in 1 mowing function allows the user to choose between collection, rear discharge, side discharge and mulching. Collect the grass clippings in the EasyClick 70 litre collector with fill level indicator that lets you know when it requires emptying. Rear discharge ejects the clippings from the back of the mower where they can be left to wilt back naturally. Side discharge ejects the cuttings to the side of the machine, leaving them in neat rows as you mow. Mulching is particularly beneficial, especially in hotter, drier conditions. Mulching reduces the cuttings in to tiny pieces and then blows them back on to the lawn where they virtually disappear. These tine pieces then provide grass roots with additional nutrients and moisture, promoting healthier regrowth.

7 cutting height positions ranging through 30-80mm can be adjusted with the spring assisted central lever. Start from the highest position and work your way down for the best cut and finish to your lawn.
