Bosch Rotak 43 LI Ergoflex Cordless Lawn Mower (1 battery)

New for 2016!

More Power, More Time, More For Your Money

Imagine a world where you could cut your lawn, free of those annoying cables or toxic fumes! Take a giant step towards the future of mowing with the Bosch Rotak 43 LI Ergoflex lawn mower. While your neighbours labour away with their noisy, cumbersome petrol mowers, you can quickly get to grips with your mowing with the more powerful, lighter, quieter, cleaner Rotak 43 Li Ergoflex. Ideal for those larger domestic gardens - cutting rounds trees and shrubs, whatever the terrain will be a breeze with the Rotak 43 Li.

The biggest headache for any gardener using electric power is the worry of cutting through the electric cable. Even the most diligent person is at risk of doing this. Well say goodbye to those worries and get yourself a cordless lawn mower! Once you start using your Rotak 43 Li you will wonder how you ever coped with petrol or electric in the past. You might not exactly think of yourself as an eco-warrior, but that's how others will see you when they know you have abandoned your petrol or electric lawn mower and opted for zero emissions cordless power. Just think no more trips to the petrol station, no more fumes and leaks to concern yourself with. The Rotak 43 Li offers you a greener alternative to gardening, an absolute must for the forward thinking gardener of the 21st century!

Those clever designers at Bosch bring you a cordless lawn mower that is more powerful, yet quieter, lighter and easier to manage than its petrol or electric counterpart. The battery favoured by Bosch is the all powerful hi-tech 36V/4.0Ah lithium-ion. The best feature of this battery has to be the ability to store it fully or partly charged and not lose any power. Special protective electronics ensure that lithium-ion garden tools from Bosch achieve a maximum service life. The energy reserves are quickly replenished thanks to the fast battery chargers. This ensures that you immediately have access to the full battery power again.

The technology inside the Rotak 43 Li may be exceedingly practical, but the outside looks the business as well. Turn heads as you glide around obstacles in your garden knowing you are safe to roam wherever you please, no longer choking on fumes or restricted by power cables. 

Bosch have really pushed the boat out with the Rotak 43Li. Its absolutely packed with user friendly features, the fact that the handles collapse to make for easier storage isn't even the beginning. Enjoy outstanding cutting performance thanks to the hardened steel blade and innovative airflow technology. With a 43cm (17”) working width and built in grass-combs you can mow right up to the edge of your lawn, and you will most probably find your lawn trimmer is redundant now!  

The bane of any gardener's life must be achieving that perfect lawn only for it to be covered in leaves and garden debris. But with the Rotak 43Li never fear! Unbelievably it offers yet another user friendly feature in the shape of a leaf collection system.

Comfort and ease of use is at the forefront of Bosch's design. Its smooth running rubber coated wheels are not the only thing you will notice the first (and every) time you use this Rotak 43li. The handles have been ergonomically designed with maximum comfort for the user in mind. The handle bar offers you a firm grip, while the mower itself gives you easy to reach controls and fold away handles, making storing and transporting a walk in the park.

Ergo Flex System

Bosch is adding a decisive product feature to its Rotak lawnmower models: the “Ergo-Flex” system. As a result of this, the Rotak mowers are now even easier to handle and also relieve the strain on the user’s arms and back. The multi-position handle and an adjustable work height make it possible to mow in various comfortable postures. Gardening enthusiasts can therefore work in an upright and relaxed position, and their muscles, tendons and joints are relieved of strain and supported. Mowing requires much less effort.

Excellent mower - Review by Ron Hill
Build Quality
Ease of Use
Value for Money
I have the cable version of this mower which I was very pleased with except for the cable which is to me a complete nuisance so I was well aware of the mowers capabilities and this battery version is just as good, the battery last for more than both front and back gardens and recharges in quick time the finish is superb due to the rear roller, It's light weight makes mowing a pleasure, I've not used it on long grass as I tend to keep mine short but I should imagine it would be fine. It collects all the grass no problem. All in all an excellent mower thoroughly recommended (Posted on 23/08/2017)
Does the job very well - Review by Anthony Standing

Ease of Use
Value for Money
Purchased this to replace Bosch Rotack 40 corded which had burnt out after good service.

The only fault I can find so far is that two of the clips that hold the halves of the grass box together were broken off when received. It is lighter and easier to use without the lead and cuts the grass very well, it is a sham that the two clips that are missing are at the top of the box and allow the grass to blow out at the user.

Excellent Mower with one minor niggle - Review by Tony

Having had two Bosh Rotak corded mowers before over the last twenty years, I decided to invest in the same model only cordless. It does the job very well. A neighbour who has the same model and a similar size garden purchased a two battery model but advised me that one would be sufficient and it is, so that was a saving. It is a dream not having to get the long extension lead out and not having to watch out where the lead is all the time. It has cut my mowing time for two lawns by at least twenty minutes and is a lot less effort.
Now to the little niggle when I put the grass box together two of the clips to hold the two halves together were broken consequently it is a bit loose. (Posted on 28/06/2017)

I'm so pleased with my mower. I have quite a lot of grass, not really lawn, and wondered how this mower would cope with long wet grass. It is brilliant. After using an old pull cord motor mower for years this is so much easier. I also feel pleased that the mower is 'greener' as I
no longer pollute the air with petrol fumes and noise. The bonus of the free blade was great. I found the grass box a little tricky to assemble on my own but persevered and managed it. I have recommended this mower to my friends.. (Posted on 04/06/2017)
Brilliant! - Review by Maureen Thomas

I chose this wider machine as replacement for my beloved mains electric mower. Like another reviewer I found the grass box difficult to fit together. I was fortunate that it was a warm day so I was able to flex and persuade its parts. The Rotak 43 mows extremely well, 8" (20cm) high tough grass even responded well when mowing on high cut. I wasn't particularly wanting a rear roller but it does make a flat lawn look marvellous! I have found the battery to last a good hour and the amount of time saved with not having to check oil, fill up or pull start a petrol mower meant I reached a coffee break earlier and unstressed. So glad I discovered this mower - and Just Lawnmowers, too. (Posted on 18/06/2016)
Fantastic lawnmower! - Review by Jenny
Build Quality

This is an excellent lawnmower in every respect, worth the price. It is light and manoeuvrable, and cuts the grass really well. It cuts right up to the edges. It is great at collecting cuttings leaving nothing on the lawn. It does not clog up at all and only starts dropping grass when the grass box is very full, but still goes on mowing. The battery still had 2 bars lit after 15 mins mowing through unevenly cut grass with a patch of very long tufts where my old mower gave up.

I have seen this marked down on reviews because the grass box is fiddly to assemble, and yes it is a bit, but it only took me, a very petite pensioner, about 15 minutes, and once it's done that's it, it is sturdy. It is definitely not a problem. The mower otherwise is very easy to assemble, I had it up and running very quickly. I can lift it with one hand so it's easy to put away. If I have one tiny niggle it is that grass gathers in all the nooks and crannies, including the corners of the grass box, but as the machine is so easy to clean this does not really cause a problem. Maybe once my grass is cut more regularly there won't be as much loose cuttings. The height adjustment is straightforward, and there is a good range of cut heights.

I have only a medium sized flat lawn but my old petrol machine struggled and finally gave up - thank goodness as I was sick of having to call my husband to start it for me and then spend ages cleaning it as it was heavy and could not be turned over. I am so glad I have this, my lawn will be mowed much more often this summer.

Great service and quick delivery too!
