The SP425 has the same great features as the HP425 with the addition of power driven rear wheels. This takes away the effort of pushing the mower; simply pull the clutch lever and away you go. Release the lever and the wheels stop - it couldn't be easier!

The Mountfield SP425 is a general purpose self propelled lawnmower, with a 41cm cutting width and powered by a Honda GCVx145 OHV engine, with a standard recoil rope starter system. The single lever height adjustment offers 6 pre-set cutting positions, from 22mm to 65mm, so adjusting the height of cut is quick and simple.

This versatile mower is referred to as a 4-in-1, meaning that you have the option to collect, mulch, rear or side discharge the grass clippings. If you choose to collect, the cut grass will be blown into the easy to remove 60 litre collector that also features a bag full indicator.  If you choose to mulch, you simply insert the mulching plug into the rear discharge chute; mulching is a great option as it can save you time, effort and money as well as providing a natural fertiliser for your lawn.

This great little mower is a joy to use and extremely economical to run. With a robust steel chassis, powder coated in silver, it will give you many years of service.

The smaller 41cm deck, makes it very nimble between the flower beds on small to medium sized gardens, of around 20m x 20m.
