Bosch Rotak 43 LI Ergoflex Cordless Lawn Mower (Bare Tool, no Rear Roller)

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.

Please note: No roller. Bare tool only. You will need to purchase battery + charger if you do not already own them

Syneon Chip

Optimum power.
More performance. Longer lifetime.

The Syneon Chip is an intelligent electronic control system for Bosch cordless tools. It controls the performance ratio of current and voltage which is output to the motor according to what the application demands. Your advantage: Thanks to its Syneon Chip, the Bosch cordless tool always provides optimum power even in demanding jobs such as work with thick screws or dense wood. At the same time, it automatically ensures compliance with the current and voltage limits. The Syneon Chip therefore prevents overheating – and increases the lifetime of your Bosch tool.

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
