Tried and Tested: Webb Lawn Mowers
Reviewed by Tommy CrossGarden TV Presenter andLandscape Business Ownerwww.myhomeground.co.uk

This aluminium decked machine is available in two sizes and both are more than capable of tackling even the most grandiose of gardens – I set both models to work on an area of paddock grass lawn approximately 0.8 of an acre in size. with the lawn, roughly 4 cm in length – and they provided great results – as would be expected from a brand whose heritage is based on mowing machinery excellence!
Both machines look the part too – the iconic Webb logo and the classic “racing green chassis” topped off with a premiumBriggs and Stratton Engine. The 21″/53cm uses the 163cc Briggs and Stratton Engine while the smaller (but not by much!) 19″/48cm has a 150cc engine. The body looks and feels strong as too do the pilot handles – all secured tightly into place using the quick-release levers. The wheels are big, grooved and rugged enough to withstand the verges and gravel paths/areas in the yard and grounds. Ideal for maintaining traction over terrain, but it was in the rough stuff where both mowers really come into their own – I was able to devastate the dandelions, blitz the banks and mow down the meadow grass in the paddock without either unit skipping a beat.
Down at the business end, the clever cutting blade comprises four retractable steel blades – much shorter than a conventional mower blade – these are secured on individual mounting nuts allowing the blade to push back into the main rotary disc – meaning if – as we did – you hit the odd stone/brick/manhole cover you will avoid causing either your mower or the driver any damage! But this is NO gimmick – both units gave crisp consistent cuts on formal and paddock grass – and the generous grass boxes ( a HUGE 70LTRs! on the 53cm unit) filled up evenly without any noticeable “side spray” or jamming.
The 53cm unit comes with a side discharge – which is great on paddock or meadow grass! Webb could have been forgiven for compromising here but the side chute felt strong and attached easily and securely leaving neat lines of fine mulch across the lawn! The single lever height adjustment felt strong and smooth as too did the start of both units. The self-drive is smooth and powerful – finding the sweet spot somewhere between pedestrian and pacey! It was also a real asset on the steep banks around the garden.
“This is a brilliant mower for large areas of lawn and would be ideal for someone wanting to maintain grounds, paddocks or pasture without having to go to the great expense of a commercial-grade mower. The Webb 19 and 21″ Petrol Aluminium Deck Mowers are both built like tanks and you’ll soon be conquering the grounds or garden with them in no time! ”
What I liked
Build quality, Power, Retractable cutting blades, Large strong wheels, and HUGE collection bags. The Webb Petrol Aluminium Deck Mowersare both built like tanks and you’ll soon beconquering the grounds or garden withthem in no time!
