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.

Lightweight, cordless mower with strong battery life and two batteries included. Cuts well, easy to maneuver, and offers good value. Some find assembly tricky and build quality plasticky.

Light and easy to use.
I have been wanting a battery mower for ages. This one doesn’t disappoint. It cuts well and stays charged for ages. It is a bit tricky to put together but there is a very helpful YouTube video to help you. I was lucky enough to get the mower in the sale- a great price.

Pleased with cutting and grass box to later mulch.
I was able to cut longish grass and the box received it well which I then put the cut grass around trees and plants as a mulch. Very happy with this purchase, Also pleased to have two batteries so I can continue to mow after the first battery has done its job.

Excellent first cut
Good to have two batteries. One sufficed to do my lawns and grass verge. Cut well up to the edges of the lawns. Found it difficult to set up but then I am not particularly good at such things. The handles caused me most problems.

Title good and easy to use
I have only had my blue machine for a couple of days but have enjoyed one cut of lawn. The lawn likes it and so do I. It is also quite easy to move around and although a little noisy I don’t think it wakes the any snoozers around the area.

Spear and Jackson 40v lawnmower
Fantastic lawnmower cuts really well, love the fact it has 2x40v batteries loads of life for a large garden.

Great cordless mower.
Bought to replace a 15 year old Spear and Jackson petrol mower whose self drive function had broken and could not be repaired. I knew this battery model did not have self drive but is much lighter and more easily pushed up slight slopes. It has worked well. It is easy to assemble ( even the grass bag). It has 3 batteries which charge fairly quickly. It cuts h grass well and the mulching plug works perfectly. I would recommend it highly.

It’s cordless
I am so pleased with my lawn mower. It’s brilliant that it’s cordless. And so easy to change the cutting position.

Battery compartment tight fit.
This product is well designed a little lightweight but generally good value. Easy to assemble and operate battery life as usual disappointing, this area needs more research.

Easy Height adjustment, easy fold down for storage
After a lot of comparing diff brands, battery & size of blade handle folding etc I am so pleased with my purchase. I already had a corded Spear & Jackson (off a on line retailer ) but got so mad having to get the extension real out, making sure I did not get the cable stuck round a bush or run over it I decided to go with a battery operated model after seeing a neighbour using a his (very jealous) I was panicking thinking i will need at least two batteries (this comes with a spare) but i don't think i will need it. Whole lawn done in 40mins tops, Lots left on the battery.I have 'STRIPES' for the 1st time.A great purchase, well made,t he handle position has 3 hts to set, easy collapse with the fold down arms for storage. Purchase was approx £100 less than the other model I was looking at in Argos and others on line. Highly recommended. Comes with a mulching plug and easy to maneuverer

Great Features
Well made mower with two 36/40 volt batteries. Chose this mower based on decent size of cutting width of 42mm plus the added power of batteries. One battery appears to last roughly 1 hour of cutting grass so with the benefit of two fully charged batteries it is sufficient to allow the cutting of our fairly large lawns. The mower is quite easy to push although with a full grass cuttings bag it does add a bit more weight to the pushing. The cuttings bag has an indicator when bag full which is very useful and saves stopping the mower to check grass bag. A well made mower very easy to use and operate. A plug in power key next to battery holder is useful as when removed there is no power to mower and then safe when moving during cleaning or placing in storage.

Hello Chris.
After checking with our supplier, they have advised for Spear & Jackson 42cm Cordless Rotary Lawnmower - 40V.
Yes, this lawnmower does have a brushless motor.
Thank you for using Q & A.
Hello Robs,
The supplier has advised the following for the Spear & Jackson 42cm Cordless Rotary Lawnmower - 40V:
"The mower is suitable for large gardens and can handle a slightly uneven or bumpy lawn. However, deep holes, mole hills, exposed roots, or rocks could be a hazard as the blade may hit them.
If the grass is long, start by using the mower on a higher cutting height, and cut it down in stages for best results."
Thank you for using Q&A.

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
