About this product
With an extra-wide 42cm cutting width, this Spear and Jackson mower has been designed especially for larger gardens. Supplied with two powerful 40V 4.0ah batteries, and a fast one-hour charger, you can use one battery whilst the other charges. And, being cordless, you can keep your lawn neat and tidy without the risk of cutting the cable.
The comb on the side of the mower brushes grass into the blades to ensure you can cut right up to the edge of your lawn, reducing the amount of trimming required.
Easy cut height adjustment means you can quickly change the cutting height to suit your lawn. There are 6 cutting heights on this mower, with a cut height range from 2.2cm to 7.2cm.
A built-in rear roller helps you achieve a precise, professional striped finish on your lawn. The mower has a 40L grass collection bag, and a mulching feature that cuts out the need to empty the grass box, leaving a fine mulch on the lawn.
The soft grip, ergonomic power handle offers improved comfort and grip. For extra peace of mind Spear & Jackson offer a 3-year guarantee on all Garden Power products.

Most excellent machine
Replaced my old mower with this cordless version wondering if the batterie would have enough power. Two batteries were supplied but I found one was enough to mow my back and front lawns, (very satisfied customer) John Tilbery

Excellent piece of kit.
Cuts superbly well, motor speeds up when the going gets tough. Two batteries provided, but one lasts so long I don't generally have to use the second one. Grass box holds a lot of cuttings. Overall, really pleased.

Good Solid Lawnmower
A lawnmower that cuts the grass very competently. It just has the advantage of being cordless. With two batteries it is easy to keep cutting for our whole lawn. In fact one of the batteries was sufficient to cut my entire lawn.

Great mower, pity about the battery charger
Mower was fine, very light and easy to manoeuvre. Unfortunately the battery charger stopped working. As it was still under guarantee, Argos replaced everything, although I would have been happy just to have a new charger. Seems a waste, but at least I have a working lawnmower.

Does the trick
Easy to assemble . Cuts lawn a treat . Batteries come nearly fully charged so can use straight away would highly recommend this product
Katie Perfect, 55 - 64, West Yorkshire
Does the job but very plasticy
This is my second S & J lawnmower. My last one broke so this is the guarantee replacement. The guarantee is for 3 years so that is a great positive. Buying from Argos made it very easy to exchange. However i am not suprised the lower handle snapped. Too much of it is plastic. I also had to have replacement handle levers several times, though they were covered by the standard guarantee. This does actually cut the grass really well, and is easy to use. Very easy to start up, just button! If you prefer a quality machine then this is not for you.

Poor customer service
I bought this in Spring and have already had to replace it

My new Spear and Jackson mower
The mower is perfect as it’s light, easy to use as it’s cordless, the basket holds a lot of grass. Building instructions were poor though.

Hello there,
After checking with our supplier, they have advised for the Spear & Jackson 42cm Cordless Rotary Lawnmower - 40V: This mower is a cordless mower and can only be operated via either of the 2 supplied batteries. It can not be operated by the mains. By having 2 batteries, one battery can be used in the mower whilst the other is charged in the fast charger provided, therefore there shouldn’t be any risk of running out of charge when cutting your lawn.

Hello Rob,
The supplier has advised the following for the Spear & Jackson 42cm Cordless Rotary Lawnmower - 40V:
“ This model is a push mower without power driven wheels. Cordless mowers are considerably lighter than petrol mowers and so the need for power driven wheels is reduced when using cordless lawnmowers. Power driven wheels on a cordless mower will also drain the battery quicker, reducing the cutting time, so is not required. ”
Thanks for using Q&A.
I'm sorry I don't know. The one I have I find is light enough. I do hope you find what you need

Hi Flossy
Having checked the instructions for the they advise:
Do not cut wet grass because it tends to stick to the underbody of the lawn mower, preventing the
proper discharge of grass clippings. Mowing wet grass, can also damage the grass.
Hope this helps.
