Webb 40V Self-Propelled Lawnmower (47cm, 2 x 4Ah Batteries)

How much power does this mower actually deliver and where does it come from?

The mower runs on two 20V batteries that combine to give 40V of cutting power. Each battery has a 4Ah capacity so you get two batteries included in the box, not just one. This twin-battery setup is what drives the brushless motor, which handles larger lawns without bogging down. Why brushless? Because it runs more efficiently, stays quieter and lasts longer than a standard brushed motor. No petrol, no extension cords, just battery power doing the work.

What cutting heights can I set and how do I change them?

You get 7 cutting height positions ranging from 30mm up to 75mm. That's a decent spread for everything from a close spring cut to a longer summer trim. Adjustment is done with a single lever, so you're not fiddling with multiple wheel clips one at a time. One lever, one motion, job done. This matters if your lawn has uneven patches or you want to change height between seasons without wasting time.

How big is the grass collection bag and how often will I need to empty it?

The collection bag holds 65 litres, which is fairly generous for a 47cm mower. A bigger bag means fewer stops to empty it, especially useful if you're mowing a medium to large garden in one go. If you'd rather not collect at all, you can switch to mulching or side discharge instead. The bag is just one of three ways this mower handles cuttings.

Can I mulch instead of bagging the grass?

Yes. This is a 3-in-1 mower, meaning it can mulch, side discharge, or collect into the rear bag. Mulching chops clippings finely and drops them back onto the lawn, which returns nutrients to the soil rather than wasting them in a bag. Side discharge is handy when the lawn is longer and you don't want clippings clogging the deck. Three functions in one machine gives you flexibility depending on the condition of your lawn that day.

Is this mower good for slopes or bumpy lawns?

It's self-propelled, so the drive system pulls the mower forward rather than you pushing the full weight yourself. This makes a real difference on slopes or uneven ground where a push mower would tire you out quickly. You still guide it, but the mower does the heavy lifting on the drive. Combined with the 47cm cutting width, you'll cover ground faster with less physical effort.

How do the batteries charge and what's included?

The mower comes with two 4Ah batteries and a USB Type-C charger. USB Type-C is a modern charging standard, so it's a straightforward, familiar connection rather than a proprietary plug. Both batteries are included in the box, so there's no need to buy them separately before first use. Keep in mind exact charging times aren't listed, so check the manual that comes in the box for precise figures.

How do I store it when I'm not using it?

The handles fold down and the mower is designed for vertical storage, so it takes up less floor space in a shed or garage. Assembled dimensions are 151.2cm deep, 67cm wide and 103.3cm tall, but folding the handles shrinks that footprint considerably for storage. If shed space is tight, this is a genuine consideration worth factoring in before buying any mower.

Does it need assembly and does it have lights for low-light mowing?

Yes, assembly is required out of the box, though this mainly involves attaching and unfolding the handles rather than complex mechanical work. It also comes with LED headlights built in, which help with visibility if you're mowing in early morning or evening light when natural daylight is fading. Small addition, but useful if your schedule means mowing outside peak daylight hours.
