Bosch Professional GRT 18V-33 - Cordless Brush Cutter 18V 4Ah

The Bosch Professional GRT 18V-33 is a cordless brush cutter designed to ensure high performance, user comfort, and great freedom of movement in garden care. Thanks to the powerful brushless motor integrated into a robust aluminium housing, this tool offers long operational life, reduced maintenance, and excellent efficiency even in the presence of tall grass or particularly resistant weeds.

The cutting system uses a 2.4 mm line with a Pro-Tap head equipped with EasyWind technology, allowing for quick line rewinding without having to open the spool. The 33 cm cutting diameter is ideal for working in large spaces, while the adjustable speed between 4,500 and 6,400 rpm allows you to adapt the power according to the type of vegetation, maintaining a constant speed thanks to electronic control.

Among the smart functions, the Bosch anti-tangle stands out, preventing the usual jams caused by weed accumulation, improving work continuity. The D-handle is adjustable to suit the user's posture, and the included shoulder strap helps distribute the weight better – only 3.5 kg without battery – during longer sessions.

The equipment is completed with a plant protection guide, useful for working precisely near edges, trees, and other obstacles. The brush cutter is compatible with all 18V batteries from the Bosch Professional platform and the shared AMPShare system, enhancing usage flexibility with other tools in the same range.

The GRT 18V-33 comes with a shoulder strap, complete head, and plant protection. Included are an 18V 4Ah battery and the corresponding charger.

Quiet, practical, and extremely efficient, this model is the perfect choice for demanding users who want a reliable tool for maintaining their garden, even in residential areas where noise must be kept to a minimum.

Battery-powered motor.

At the front, there is the housing for the 18V battery. There is also a compartment for a spare battery.
The 18V lithium-ion battery can be recharged at any time (like modern smartphone batteries, it has no memory effect) to always have it ready for use. It lasts on average 30 times longer than a regular battery. The battery is equipped with a convenient charge indicator.

Advantages of the battery-powered electric motor

• More reliable than a petrol engine, thanks to its electric motor. It has no spark plug, filters, fuel lines, carburettors, etc., which are components prone to problems
• Much lighter
• Zero maintenance, for the same reasons mentioned above
• Lower consumption and drastically reduced operating costs compared to petrol models (you can cut with just a few cents of electricity). Also, you don't always have to procure fuel (which should always be fresh).
• Zero vibrations, again thanks to the electric motor. In contrast, almost all petrol systems, which are not equipped with a steel spring anti-vibration system, have a very high degree of vibration, making the work really uncomfortable
• Zero fumes, zero harm to the environment and especially to the health of the user
• Much quieter and therefore more pleasant to use compared to petrol engines

The brush cutter's drive shaft has a diameter of 26 mm and is made of aluminium. This makes it very durable while keeping the weight low.

The weight of the machine without batteries is 3.5 kg and 4.1 kg with the battery (4.0 Ah).

The adjustable handle both on the shaft length and for inclination makes the brush cutter adaptable to anyone.

The controls are simple and intuitive, as there is only the power button and the operation button.

The Pro-Tap head with EasyWind technology is designed to simplify and speed up line management, ensuring a smooth and uniform line feed during work. Thanks to the easy winding system, it is possible to rewind the line directly from the outside, without opening the spool, reducing downtime and making maintenance easier.

The 2.4 mm diameter line offers greater wear resistance and is ideal for tackling tall grass and tough weeds, while ensuring a clean cut along edges, walls, or obstacles. The round profile helps limit kickbacks and protects surfaces in case of accidental contact.

The head is integrated with the Bosch anti-tangle function, which reduces the risk of jams caused by tangled grass around the motor shaft, improving work continuity and safety.

The 33 cm cutting diameter ensures wide coverage with each pass, making this system perfect for both trimming and more intensive interventions in medium-sized gardens.

Robust, practical, and highly efficient, the Pro-Tap head with EasyWind completes the performance of the Bosch GRT 18V-33, offering the user a precise, fast, and uninterrupted cutting experience.

LONGER LIFE: up to 3 times longer than traditional nickel-cadmium batteries, reducing the need to recharge during long periods of use.
Ideal for medium-large gardens.

FULL CHARGE FOR THE ENTIRE BATTERY LIFE: the charge of lithium-ion batteries does not fade. Unlike nickel-cadmium batteries, whose power gradually decreases, lithium battery cells maintain constant power throughout the entire cycle. You get practically the same charge from start to finish, without reducing the motor's rpm. The battery operates at full power until it is completely depleted.

LONG CHARGE LIFE: Lithium batteries boast 3-4 times more recharge cycles than traditional nickel-cadmium batteries, while also having longer storage times with
less charge loss. With lithium batteries, you can do up to 2,000 charge cycles!

LIGHTER WEIGHT: Lithium batteries offer the best power-to-weight ratio. On average, they weigh 1/3 of nickel-cadmium batteries.

ENVIRONMENTALLY FRIENDLY: Lithium battery tools are recyclable and are produced without heavy metals.

NO MEMORY EFFECT: Lithium batteries can be recharged at any time without negative memory effect, they can indeed offer maximum power even after hundreds of charge cycles.
A few minutes of charging are enough to provide the necessary power to complete the work.

LOW DISCHARGE RATE: Low charge loss rate (up to 5 times lower than nickel-cadmium batteries) so your tool will be ready to use even after months of inactivity.

CHARGER: Lithium battery chargers allow for an average energy consumption reduction of 35%.

INCLUDED IN THE PURCHASE, A LITHIUM BATTERY AND THE CORRESPONDING CHARGER

Battery with quick-release attachment: it detaches and slides out of the machine with a simple gesture, just press the quick-release button.

Voltage: 18V
Amperage: 4 Ah

The practical battery can be recharged at any time, without memory effect (it does not tend to run out after many recharges) to always have excellent power.

Included is a practical charger (connects to the home power supply like a phone charger).

The battery attaches to the charger through the quick-release attachment, in the same way it attaches to the trimmer.

Additional batteries can also be purchased to have a very extended working autonomy.
