The shoulder-mounted brush cutter RURIS RR3845e is a gardening tool powered by a 40V 5 Ah Li-Ion battery. This tool has the advantage of being quieter and easier to handle than internal combustion engine brush cutters, as it doesn't require fuel and doesn't emit exhaust gases. In addition to these advantages, battery-powered brush cutters also offer greater freedom of movement as they are not dependent on an electric cable.
Ruris Alfa UP Innovation
Users can be confident that the battery will be ready for use even after a long period of storage. The RURIS ALFA UP innovation, through its function that allows the battery to be restarted after storage between 6-12 months, brings numerous benefits to Li-Ion battery-powered gardening equipment, protecting the battery from damage.
Interchangeability and Versatility By purchasing a RURIS product, your garden can now benefit from all RURIS equipment at a reduced cost, as Li-ion batteries are interchangeable.
Performance
The brush cutter's brushless electric motor is an advantage as it requires no maintenance and has a longer lifespan than brushed motors. The total power of 200 Wh indicates the amount of energy stored in the battery, and this value indicates that the brush cutter can be used for several hours depending on the intensity of use. Additionally, the 40V 5 Ah Li-Ion battery provides sufficient power for cutting grass.
The cutting diameter with a trimmer line of 380 mm and the cutting diameter with a blade of 255 mm allow the user to choose between multiple cutting options, depending on the working area and your needs. The 26 mm tube diameter and the rigid and modular drive shaft ensure increased stability during use, resulting in more precise and efficient cutting.
Comfort
The ergonomic two-segment handles ensure a comfortable grip and easy handling of the brush cutter, while the low vibration level reduces fatigue during use. Additionally, the weight of 3.8 kg makes the brush cutter easy to maneuver and transport.
Ecological
Another important advantage of the shoulder-mounted brush cutter RURIS RR3845e is that it doesn't emit exhaust gases, making it a more environmentally friendly option than gasoline-powered models. Additionally, the electric motor requires easier and cheaper maintenance than a gasoline engine, as it doesn't require oil changes and other related maintenance.
Portability
Due to the absence of a power cable and the presence of a powerful and lightweight battery, users can cut grass anywhere without being limited by the presence of a power source or a limited cable length.
Reduced Noise
The shoulder-mounted brush cutter RURIS RR3845e is also quieter than gasoline variants, making it suitable for use in residential areas or near homes without disturbing neighbors. Additionally, due to the fact that there is no need to fill a fuel tank or handle flammable liquids, using this type of brush cutter is safer and easier.
