Durable and Powerful SP425 Self-Propelled Mower

Mountfield's SP425 has the huge benefit of power driven rear wheels, which make it easy to use on sloped terrain, as well as simply taking the strain off the operator in general use. Just pull up the clutch lever and the machine will move - release the lever and it stops.

Honda-powered supreme cutting performance

The 41 cm / 16 inch cutting width makes it ideal for lawns up to 20m x 20m, with the reliable Honda GCVx145 autochoke engine ensuring it is more than capable over this sort of area.

Customise the cut for a perfect finish

To get the perfect finish for your lawn you have a number of customisable options. You can choose from 5 pre-set cutting heights, from 22mm to 65 mm using a single height adjustment.

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.
