A great mower that's also economical to run.

The SP425 Mountfield lawn mower has the same features as the HP425, with the addition of being power driven. Power driven machines are controlled by a clutch lever that you simply pull in order for the machine to move. To make the machine stop you just release the clutch lever and it will stop moving forward.

Supreme cutting performance

You can choose from 6 different cutting heights, ranging from 25mm-65mm. This is adjustable quickly and easily by using a single lever. Because the cutting deck on this machine is 41 cm / 16 inches, it makes it nimble and small enough to fit between flower beds and around obstacles. In fact, it is perfect for small to medium sized gardens up to 20m x 20m.

An extremely versatile machine

Featuring Mountfield's 4 in 1 cutting system, you can choose the perfect finish for your lawn. You can opt to collect your clippings into the large 60 litre grass bag (an indicator will activate when the bag is full); you can also mulch the clippings to recycle them back into the lawn (saving you time and effort, as well as providing a natural fertiliser); while you may also use the rear discharge feature, which has the grass cuttings discharged at the rear of the machine. Additionally has the added benefit of being able to use the side discharge when working.


This machine comes with a 5 year warranty.
