Bosch Cordless Garden Tools

Why Bosch battery?
The first Bosch series of cordless
garden tools that meets
the needs of professionals.

Setting new standards in performance and run time.

Petrol performance:
The unique Bosch battery gives you equivalent performance to petrol-driven tools.

The new Bosch GRA 53 Professional lawnmower cuts the same area of grass (1,500 m2/h – ca. 6 times the size of a tennis court) in the same time as an equivalent 53 cm petrol lawnmower.

Petrol performance: Comparison based on a GRA 53 and leading petrol competitor (Cutting conditions: dry grass, height 6-4cm).

1,500 m2/h

A high capacity battery for superior performance.

The new Bosch professional battery features innovative ‘cool pack’ temperature management via the aluminium cooling fins. Heat is transported from inside the battery to the outside to protect the cells. In contrast to typical batteries, the cooling of the battery allows for constant higher energy transmission to the motor, as the battery does not easily overheat.

Battery / charger
Sales and service
Can I use the lawnmower with one battery?
Yes, it can be powered with a single battery with no loss of performance, but with a corresponding drop in run time.
What is the reach of the lawnmower?
In normal usage with fully charged batteries it would be around 1500 m2, dependant on mowing conditions.
What is cast aluminium alloy?
Aluminium is light in weight but by itself is quite soft and brittle, so it is mixed with other materials to increase robustness and strength.
Is there any difference in performance whilst mulching?
The split edge design of the mulching blade cuts the grass twice using extra capacity. This offsets carrying the weight of the grass box whilst using the normal blade therefore causing performance to remain the same.
What can I do if I run out of energy?
To avoid running out of energy, we would recommend buying a spare set of batteries as the recharge time is 42 minutes so users can recharge faster than the time it takes to drain a battery. Usage of products is then not limited.
What is the reach of the brushcutter?
In normal usage with a fully charged battery, it would be around 250 m2, dependant on cutting conditions and the type of accessory being used. We have a range of different diameter lines and both metal and polymer blades in our accessories range available from your dealer.
Can I use the new PRO battery with Bosch Blue tools?
Yes it is compatible, however the power, weight and waterproof capacity of the battery are in excess of normal power tool requirements. The new PRO charger will charge any Bosch Blue 36V battery.
Do you have to change the guards?
Yes, there are three guards in the range and it is important they should be changed according to the type of accessory used.
How easily interchangeable are the accessories?
Very easy. For the blades you have to use 2 tools provided, a locking pin pushed into the hole on the motor housing to lock the rotor and a spanner to loose the nut. For the bump line head and poly blade head only the locking pin is required.
How should I recycle batteries?
The batteries can be placed in battery recycle bins.
What innovative features have lead the product to be waterproof?
The battery packs are weatherproof and the electronics are in sealed modules.
What does CoolPack technology mean?
This technology manages heating in the battery and motor to increase the life of the product.
What are the shut-off temperatures of the battery and charger (highest and lowest)?
The maximum operating temperature of the battery is 65C with a limited performance below -10C. The battery will only charge between 0 – 45C so it is recommended in hot weather to re-charge the batteries out of the direct sunlight.
Who handles PRO repairs? How does the system work?
Please refer to your dealer. Any warranty work and more complicated repairs will be done by Power Tools central service.
What is the warranty on the products?
We offer standard warranty which is the same as is available on Bosch Blue products. This is 3 years on the products and 2 years on the battery following online registration.
After extended warranty am I still supported by Bosch in any way?
Both the dealer network and Bosch central service will continue to support you in ensuring your products work to maximum efficiency.
How can you quantify equivalent petrol performance?
Our testing data has shown that our products can cut an equivalent area in the same time as petrol products.
What is the significance of half the noise?
This means users can start work earlier and carry on working later. This is also very relevant for use in noise sensitive areas such as schools, hospitals and libraries. The new PRO Brushcutters in particular are significantly quieter than their petrol equivalents.
What are the CO2 emissions of the product?
These Professional garden tools are electric driven products and therefore do not have any direct CO2 emissions.
Can the products be used all day?
Yes, products with vibration levels below 2.5m/s2allow all day work. See local regulations for clarification.
