More Power, More Time, More For Your Money

More Power, More Time, More For Your Money - two batteries included for even better time management! 

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. And with this deal you get two batteries, perfect for having one in use and one charging, meaning very little interruptions if you have a lot of work to do! 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.

Product features

  • A Power drive + motor that is quiet to run and powered by a 36v battery that will charge to 80% in only 70 minutes or 100% in 140 minutes.
  • Precision cut in most grass conditions with six heights of cutting settings ranging from 20mm-70mm.
  • A cutting width of 43cm (17”) with built in grass combs and a hardened steel rotary cutter blade ensures a precise cut, in almost any grass conditions.

  • A 50 litre collection box ensures less interuptions through less trips to the compost heap making your job more efficient.

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.

Comes complete with:

  • 50 Litre Grass box
  • AL 3620 (140 mins) charger for lithium-ion batteries
  • 2 x 36 V/4.0 Ah lithium-ion batteries

Great apart from cuttings box assembly - Review by William Shaw
Build Quality
Ease of Use
Value for Money
This mower took care of our medium size lawn using about 2/3 of one battery, so works really well for us. The mower is very easy to use and makes decent stripes. It can choke a bit on longer or wet grass unless you have it on a high setting, but that is the case for many mowers. It's great not having a power cord to trip over or electrocute yourself with. It's also a Which best buy amongst the cordless family.

A couple of irritations - assembly of the cuttings box is a total pain. It's fine when its done and on but is a shoddy design. I'd rather have had a bigger box for the whole product with a complete cuttings box ready to go. That's why I have marked down ease of use. The other irritation is the free strimmer. I have deliberately gone cordless so would rather have had some money off than a corded free strimmer. It's not very good anyway.

This mower is not cheap but does a great job if you can afford it and don't have a fatal strop assembling it. (Posted on 21/09/2016)

My wife and I have both been using this mower for a month now and we're really impressed with it. It's light, easy to use and manoeuvre, gives a great cut and I've been amazed at how long the battery lasts in between recharges. Highly recommended. (Posted on 24/06/2016)
Excellent Lightweight and Quiet Running Bosch Cordless Lawnmower - Review by Kate Tucker

Value for Money
As a lady gardener mowing lawns for clients I find this mower easy to use, easy to lift out of the car boot and beautifully quiet. Having very happily used the corded version for the last 3 years the freedom of cordless and lack of need for extra cabling is excellent. None of those difficult getting the cable caught on a plant and potentially breaking off a piece. So far I'm getting around 1 hour 15 minutes per battery. Over the years I've become a bit of a Bosch fan and their rapid recharging makes their tools very efficient. Ryobi by contrast takes almost twice as long to charge so the faster charging is worth the extra money to me. (Posted on 08/06/2016)

Been using it about three weeks to cut all sorts of grass some very long and unkempt. It has been highly praised by three operators.

I'm very pleased with the Bosch battery powered mower. After having had a shoulder injury and surgery I was torn between buying it and another Honda powered mower. I decided that although I would have to push the Bosch the fact that it would be light weight would make it easier to get in and out of the garage and around plants around the lawn. I was worried that the battery would not last for one complete cut, so I bought the two battery version but need not have! It has not needed a battery change until all of our lawns (over one tennis court size) have been completed. It's so light weight but is really effective leaving stripes as well without a trailing power cable. Very pleased with the mower it's made mowing so much easier and quicker. The service provided was also faultless. (Posted on 30/04/2016)

If you'd asked me whether I'd ever own a battery powered garden lawn mower, I'd have scoffed. How wrong I was. Battery power, using LiOn battery technology has revolutionised battery products from the NiCd days! I had two busted mowers, one electric, one petrol. Prompted by my wife (SWMBO) to consider these battery models after being fed up of me moaning about tripping over mains flexes, I looked into the Bosch Rotak Li range of mowers. After reading other reviewers I decided try buy one. What is not to like. No mains cord, no petrol, no oil, no starting problems, no servicing costs. My new 43Li is a dream. It weighs in at 18kgs so much lighter than a 40kg aluminum decked petrol variant - so easy to man-handle to shed or car. Multi height one lever adjuster, Ergonomic folding handle. Cuts to the edge with metal blade with very smooth plastic cutting area underside - so doesn't clogg. Respectable 50ltr grass box which well engineered for on/off emptying. Battery charges very quickly and lasts an extremely respectable amount of time. the claimed 600m2 is more than accurate. I have done 2 cuts of the rear 30x10m grassed area before migrating to the front 5x5m grassed area and there is still one battery bar left. Have also used on the grassed areas at our allotment with great easy and success - still has plenty of capacity after that too - so, very impressive battery capacity (after charging they maintain charge until next use). The package I secured comes with 2x4Ah batteries and charger. So, impressed with this range of garden tools I also purchased the strimmer (can purchased less batteries) - which uses the same batteries! I don't own any but they also do a hedge trimmer, chain saw & leaf blower. The final plus, built in Britain so keeps people in jobs in Norfolk. Not the cheapest electrical item but similar price to the larger reputable petrol mowers. If you are unsure, haven't made up your mind yet, don't hesitate. Very pleased indeed. (Posted on 07/11/2015)

Pleased with the mower, this was to replace a same make,but electric cable mower. My only wish is that it would cut the lawn as short as the cabled mower I have, but there doesn't seem any way of adjusting it. It's made cutting our lawn much easier although I do occasionally use my old mower to get the grass shorter (Posted on 06/08/2015)
