Lawn Mowers


The Mountfield SP42 lawn mower is not only our cheapest self propelled lawnmower with mulching facility, but is also a fantastic option that is ideal for small to medium sized lawns up to 20m x 20m. It has a 41cm width of cut and a powerful Mountfeld 123 cc engine.

The lawn mower has a single lever height of cut with six positions. These range from 22 – 65 mm. The grass bag is a large 60 litres and it has a bag indicator located on top of the box. Another great advantage of the SP42 is that it comes with a mulching plug, so you can cut the grass without collecting it. This means the grass will decompose and act as a natural fertiliser.

2 year warranty included with the Mountfield SP42.

What else will I need to buy with my SP42 lawn mower?

  • Lawn mower oil
  • Petrol / Aspen Fuel
  • OR, Masseys will assemble and check your lawn mower, add the correct amount of engine oil and add some fuel all for just £10.00, so it is ready to cut grass!


As said, the Mountfield SP42 lawn mower represents excellent value for money. It is powered by a Mountfield ST120 123cc 4 stroke engine and the Mountfield SP42 is self proplled making it ideal for small to medium sized lawns. The engine is very easy to start, with a standard recoil rope system and will give many years of trouble-free mowing. Reliability can be increase by using Aspen fuel which will not deteriorate for up to 5 years.

If you would prefer not to collect the grass cuttings you could choose to mulch using the mulching included; recycling grass clippings back into your lawn can save you time, money and effort.

This great little mower is a light and easy to use and extremely economical to run and with fold down handles making it easier to store. The tough hammered steel deck is not only stylish but hard wearing and will give you many years of service.

If you didn’t want self-propelled, you might want to consider the Mountfield HP42 model or view our full range of Mountfield lawn mowers.
