Webb WER18HP4 Supreme 18" (46cm) 4 Swing Tip Blade Petrol Rotary Lawnmower

The WER18HP4 sits in Webb's Supreme range and the standout feature is the 4 Swing Tip Blade system — a design that makes a real practical difference on lawns where hidden stones, tree roots, or other solid objects lurk beneath the grass. When a blade tip strikes something solid it swings back on impact rather than transferring the full force through the blade and deck, significantly reducing the risk of damage. It then returns to position automatically — no stopping, no manual resetting.

The 125cc Briggs & Stratton 450E Series engine is a reliable, proven unit that starts cleanly and delivers consistent cutting performance across the 18" (46cm) width. Eight cutting heights from 25-80mm is a broader range than most mowers at this price point — the upper end of 80mm is useful for tackling longer or overgrown grass before moving to a finer setting. The 65-litre collection bag is generous for a hand-propelled mower and reduces emptying stops, and mulching is available as an alternative to collecting.

Backed by a 3-year warranty.
