The Metabo RTD 18 LTX BL 30 cordless string trimmer is a modern garden tool designed for efficient and easy grass cutting in small to medium-sized gardens. It is intended for users who are looking for mobility without the constraints of a cable, and for those who want to comfortably and quickly trim lawns or lawn edges even in hard-to-reach places. The main advantage of the product is its easy use without emissions, quietness and performance without the direct need for an electrical connection.

The mower solves the problem of time-consuming manual pruning and allows users to easily mow around trees, fences or flower beds, where a classic wheeled mower is often not convenient enough. Powered by an 18V battery system (CAS) means complete flexibility when working in different parts of the garden, while the cordless design reduces the risk of tripping over cables or limited reach.

Evaluation of key product features

⚖️ Compare features with other products of your choice

The brushless motor provides high energy efficiency, as it has less friction and requires less maintenance than traditional brushed motors. This means a longer life of the device, quieter operation and constant stable power during operation. In practice, this allows the user to focus on the work without frequent interruptions for maintenance.

The cutting diameter between 26 and 30 cm allows you to quickly cover a larger area in a short time, which is convenient for both regular lawn maintenance and edge trimming. The compact line head makes it suitable for mowing around obstacles, under bushes and in hard-to-reach parts of the garden. The ergonomic handle and balanced weight make it easy to work for longer periods without tiring your hands.

Using the CAS battery system brings additional convenience, as it is compatible with multiple devices on the same platform. This means that users who already have the appropriate Metabo battery and charger can easily exchange batteries between different devices. Although the battery and charger are not included, the system allows for easy adaptation for existing Metabo tool users.

The lawnmower is designed for everyday or occasional use in the home garden, as well as for larger households that want a more flexible alternative to conventional petrol or electric corded lawnmowers. With its quiet battery-powered design, it is particularly suitable for working in urban environments or at times when you want to be kind to your neighbours.

It is important to know

This cordless string trimmer is primarily intended for users who already have a compatible battery and charger from the Metabo system or want to purchase them separately. Before purchasing, it is crucial to consider whether the cutting diameter is appropriate for the size and complexity of the garden and how important portability without an electric cable is.

• The model does not include a battery and charger - if you do not already have a CAS system, purchasing it will be an additional investment.
• The cutting diameter is up to 30 cm, which means a good balance between working speed on medium surfaces and still solid accuracy when processing edges.
• Lower weight combined with ergonomics makes it easier to handle, but longer continuous work is conditional on the availability of a spare battery.
• A brushless motor means less maintenance and a longer tool life, but for more demanding jobs on larger surfaces, check that the voltage and capacity are sufficient for your needs.

Answers to frequently asked questions

Is a battery really required for operation?

Yes, you need an 18V battery from the Metabo CAS system to operate, which is not included.

Is this model suitable for very large lawns?

For larger areas (over 400 m²), we recommend a larger cutting diameter and a larger battery supply due to limited capacity with a single power supply.

Do I need a special charger for this mower?

You must use a charger that is compatible with the CAS system (Metabo or partner brands with the same standard).

Does a brushless motor mean a longer lifespan?

Yes, brushless motors generally provide less wear and tear and require less maintenance compared to brushed versions.

What if one battery runs out while working?

It is recommended to have at least one spare battery available if you want to work without long interruptions due to charging.
