Webb WER21HW4 Supreme 53cm (21″) Self-Propelled Petrol Lawn Mower with 4-in-1 Function
The Webb WER21HW4 Supreme is the largest lawnmower in Webb’s Supreme range, designed to deliver outstanding performance and durability for large gardens. Powered by a robust Briggs & Stratton 725EXi 163cc engine with ReadyStart® technology, it offers easy, reliable starting and smooth operation without the need for priming or choking.
With its wide 53cm (21″) cutting width, this mower covers more ground in fewer passes, making light work of large lawns. The self-propelled drive ensures effortless mowing across rough or uneven terrain, while the durable steel cutter deck provides long-lasting strength.
New for 2024, the mower features Webb’s innovative 4-swing tip blade system, designed to improve cutting efficiency and protect against damage. If the blades hit a solid object, the tips pivot back, reducing impact and maintaining smooth operation.
The 4-in-1 functionality gives you the flexibility to collect, mulch, rear discharge, or side discharge clippings, while eight cutting heights (20–80mm) adjusted via a single lever provide complete control over your lawn finish. A large 65-litre mesh grass collector maximises airflow for more efficient bag filling, reducing emptying stops.
For added convenience, the WER21HW4 Supreme also includes large ball-bearing rear wheels for improved manoeuvrability and a wash port for quick and easy deck cleaning.
Backed by Webb’s trusted reputation for quality and supported by UK-based aftercare, this mower offers a powerful, versatile, and reliable solution for large lawns.
