The Premium 520 SP-H self propelled 4 in 1 petrol mower offers superb features and specifications at an affordable price. Featuring the largest cutting width in the range at 51cm (20 inch) and a single speed power drive.

Powered by a Honda GCVx170 petrol engine with a taller MaxAirFlow steel cutter deck that gives improved grass collection and helps to prevent blockages in the discharge channel.

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 the user know when it requires emptying. Rear discharge ejects cuttings through the back of the mower where they can be left to wilt back naturally. Side discharge ejects clippings through the side of the machine and leaves them in neat rows as you mow. Mulching is particularly beneficial, especially in hotter, drier conditions. Mulching reduces the cuttings into tiny pieces and blows them back on to the lawn where they virtually disappear. These tiny pieces then provide additional nutrients and moisture to the lawn, promoting healthier regrowth.

7 cutting height positions ranging through 30-802mm can be changed easily with the spring assisted central lever. Start at the highest position and work your way down for the best cut and finish for your lawn.



  • 70 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: 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.
