Webb WER18HW4 Supreme 18" (46cm) Self-Propelled 4 Swing Tip Blade Petrol Lawnmower
The WER18HW4 takes everything in the push WER18HP4 and adds self-propelled drive and a more powerful 140cc Briggs & Stratton 500E engine — making it the better choice for medium to larger lawns, slopes, and anyone who wants to cover ground efficiently without physical effort.
The 140cc 500E Series engine is a step up from the 125cc unit in the push model, offering low-emission performance, superior fuel economy, reduced vibration, and quieter operation. Self-propelled drive at 3.5km/h is slightly faster than the Classic range models, and the large ball-bearing rear wheels provide better manoeuvrability on harder ground compared to standard wheels — a detail that makes a genuine difference in push effort and control on varying surfaces.
The 4 Swing Tip Blade system carries over from the HP4 — blade tips swing back on impact with solid objects rather than transferring force through the deck and crankshaft, significantly reducing the risk of damage on lawns where stones or roots lurk beneath the surface. Four cutting modes — collecting, mulching, rear discharge, and side discharge — with eight heights from 20-80mm cover every situation, and the wash port allows deck cleaning via a garden hose without getting underneath the machine. The 65-litre mesh collection bag fills completely before needing emptying.
Backed by a 3-year warranty with UK-based customer support.
