Free 1 Litre of WGM 10W40 Oil with this machine


To produce a classic stripy look to your lawn you need a rear roller. To effortlessly nip around a small lawn and to easily cut various lengths of grass, with the power of a solidly built petrol engine, you need the S421R PD.

Self-propelled, the STIGA ST140 Autochoke engine, producing 2.kW of power at 2900 rpm, drives the 41cm wide cutting blade with resultant clippings being collected in the 55-litre canvas hard top collection bag. And when the bag is full there is an indicator to tell you to empty it (mix with equal amounts of woody material in your compost heap to help produce the best garden compost ever.)

This is a powerful and efficient mower that is dependable, sturdy (the steel chassis sees to that) and backed by a five-year extended warranty. It’s a beauty if you want that stripy lawn.
