The Mountfield SP42 is a reliable, self‑propelled petrol lawnmower designed to make everyday mowing simple and stress‑free. Powered by the dependable STIGA ST120 Autochoke engine and built around a strong steel chassis, it delivers consistent performance across small to medium‑sized gardens.
With a 41cm cutting width and a centralised height adjustment lever, you can choose from six cutting heights to suit changing grass conditions. Clippings are collected in a generous 60‑litre canvas grass bag, complete with a handy full‑bag indicator so you know exactly when to empty it.
For added versatility, the SP42 also includes a mulching plug. Fit it in seconds to finely cut and recirculate clippings back onto the lawn, helping to return nutrients and reduce waste.
Lightweight at just 25kg and easy to manoeuvre, the SP42 also features fold‑down handlebars for compact storage. Backed by a 5‑year extended warranty (T&Cs apply), it’s a great choice for anyone wanting a dependable mower at a great price.
