User-Friendly S421 PD 41 cm Self-Propelled Rear Roller Lawn Mower

Ideal for garden sizes up to 20m x 20m, the S421R PD 41 cm self-propelled rear roller lawn mower creates a beautifully striped lawn. 

Features a Mountfield ST 140 Autochoke engine that produces 2.2kW of power at 2900 rpm, driving the 41 cm wide cutting blade with resultant clippings being collected in the 55-litre canvas hard top collection bag.

Includes an indicator to let you know when the bag needs emptying. It is good to note that if you mix with equal amounts of woody material in your compost heap, it helps to make the best garden compost.

This powerful and mighty lawn mower is exceptionally robust and sturdy, allowing you to complete your garden jobs quicker than ever.
