Do you want perfectly manicured lawn edges, precisely shaped shrubs and boxwood without the need for multiple devices, petrol or annoying cables? The 2-in-1 Cordless Grass Shears and Shrub Trimmer Set (SKU: RTANTK0171) is the perfect solution for easy and precise horticultural creation. With a single tool, you can easily complete two key tasks in your garden without compromising on power or mobility.
Thanks to the powerful 21V system, the device provides exceptional power and constant speed even when cutting dense bushes or tough grass. The set features a 200 mm long brush cutter, which allows you to quickly shape hedges, while the wide grass attachment ensures clean edges along fences, walls and flower beds.

Key benefits of using a 2in1 battery pack

Complete freedom of movement: You can work wherever you want – without having to search for a power outlet or tangled cables. The absence of a cord means greater freedom of movement and easier maneuvering around plants and in hard-to-reach places.
Quick-change click system: The click system allows you to change blades without additional tools and without wasting time. This allows you to quickly switch from mowing grass to trimming bushes in a single movement.
Exceptional ergonomics and flexibility: The head angle adjustment up to 90° allows you to perfectly adapt the tool to your body position. This avoids bending and lower back pain and makes it easier to reach hard-to-reach places.
Continuous work with two batteries: The set includes 2x 2.0Ah batteries with LED charge indicators. When one runs out, simply replace it and continue working.
High cutting performance: With 2300 revolutions per minute, the device ensures smooth and efficient cutting without tearing plants, which helps to work faster and make your garden look more beautiful.

Instructions for using the product:
Blade replacement and assembly (Quick click system)
• Safety first: Always remove the battery from the device before handling the blades.
• Removing the attachment: Press the side buttons on the bottom of the device head (depending on the exact model, press or push the latch) and carefully remove the current blade downwards.
• To install a new attachment: Align the drive pin on the tool with the slot on the selected blade (200 mm brush cutter or wide grass blade). Push the attachment upwards until you hear a distinct click, confirming that the blade is securely engaged.
Starting and adjusting the angle
• Insert the charged 21V 2.0Ah battery into the slot on the back of the handle.
• Angle adjustment (Switch): Press the angle adjustment button on the device's joint and turn the blade head to the desired position (e.g. horizontal for grass, inclined for shaping bushes). Release the button to lock the head.
• Power on: To start, press the side safety button and the main trigger on the handle simultaneously.

Useful tips:
• Clean the blades after each use: Plant juices and grass contain acids that can cause corrosion and dissolve the blades. After work, wipe the blades with a damp cloth and clean them with a dedicated disinfectant or alcohol.
• Regular lubrication for smooth operation: Before each use, apply a few drops of all-purpose machine oil or silicone spray to the sliding surfaces of the blades. This reduces friction, extends battery life, and ensures sharper cuts.
• Avoid hard objects: When cutting grass edges, be careful not to hit the blade against concrete curbs, stones, or wire fences, as this can permanently damage or bend the blade teeth.
• Pruning to the right size: The shrub attachment is designed for green shoots and thinner twigs. For thicker, woody branches (over approx. 8 mm), use a dedicated chainsaw or hand saw.

Warnings:
• Always remove the battery: When changing blades, cleaning grass clippings, or transporting the device, be sure to remove the battery from the battery bay.
• Use of protective equipment: Always wear protective gloves and safety glasses while working, as pieces of twigs or stones can fly towards your face.
• Hand and foot safety zone: Never place your free hand in close proximity to the operating blade to help hold branches.
• Protection against moisture: Do not use the device in the rain or to mow extremely wet grass after a heavy downpour. The housing and battery pack are not waterproof.
• Storage: Store the device with the plastic blade covers in place, in a dry place and strictly out of the reach of children.

Same summary

The 2-in-1 cordless grass shear and trimmer set with 21V voltage and two batteries is especially suitable for gardeners who want to easily switch between precise trimming and rougher plant removal. Thanks to two batteries, it allows for longer continuous work, which is important when arranging larger green areas or for more frequent garden maintenance. The brushless motor is not particularly exposed on the model, so the set is more suitable for regular hobby use and less suitable for intensive daily work or greater demands.

If you primarily need a lightweight and agile tool for various tasks around the house, this set is the right solution; for processing thicker branches or more robust tasks, we recommend choosing stronger or specialized tools.
