The WER21HW4 is the largest lawnmower in the WebbSupremerange. Featuring self propulsion, 4-in-1 capability, a high quality steel cutter deck and a premium Briggs & Stratton 725EXI engine, the WER21HW4 also benefits from a Ready Start system which means there is no need to prime or choke before starting up the engine - just pull the cord and you're away. The 65 litre grass collector has been designed so that air can flow through it, meaning that it will fill up completely before it needs emptying. After you have finished mowing, an integrated wash port in the deck enables the machine to be thoroughly cleaned and washed down with a garden hose.
