Webb WER21ALSP 53cm (21″) Aluminium Deck Self-Propelled Petrol Lawn Mower
The Webb WER21ALSP is a premium self-propelled petrol mower, designed for tackling large gardens with ease. Powered by a reliable Briggs & Stratton 750EXi 161cc engine, it combines robust performance with low-effort operation.
Built around a lightweight yet durable aluminium cutter deck, this mower offers long-lasting strength without compromising manoeuvrability. Its 4-in-1 functionality allows you to choose between collection, rear or side discharge, and mulching – giving you complete flexibility to suit your lawn care needs.
The 8-stage single lever height adjustment makes it simple to achieve the perfect finish, with cutting heights ranging from 25mm to 90mm. A generous 70-litre mesh collection bag reduces emptying stops by optimising airflow, while the innovative 4-swing tip blade system delivers a clean, consistent cut and helps protect the mower from damage.
With a self-propelled drive system, mowing is virtually effortless, even across uneven terrain. And for complete confidence, the WER21ALSP comes backed by a 3-year warranty and a UK-based customer service team, ensuring reliable aftercare and peace of mind.
