Grass and Hedge Trimmer Dedra DED8670 3.6V cordless battery-powered garden tool

Dedra DED8670 is a 3.6V cordless battery-powered grass and hedge trimmer intended for light garden maintenance tasks. The compact tool combines a grass-trimmer blade for edging and turf tidying with a hedge-cutting blade for small shrubs and border shaping. Its cordless design makes it suitable for spot trimming, quick border work and maintenance in areas without mains power access.

Advantages

The tool offers a lightweight, compact construction that makes handling and manoeuvring along borders and around plants easier. Battery power removes the constraint of a cable and allows use in remote parts of a garden. Interchangeable cutting heads provide basic versatility between grass edging and trimmed shaping of hedges and small shrubs. The simple control layout and low vibration level support short maintenance jobs without complex setup.

Suitable for

• Edging and tidying small lawns and garden borders
• Trimming low hedges and shaping small shrubs
• Quick spot maintenance and seasonal touch-ups
• Use in allotments, balconies or yards where mains power is not available

When it may not be suitable

Because this is a 3.6V compact cordless unit designed for light duty, it is not suitable for heavy-duty hedge work, thick branches or large-scale property maintenance. Extended continuous use may be limited by battery capacity and motor power compared with higher-voltage or petrol-powered models.

Key specifications

• Power type: rechargeable battery (cordless)
• Rated voltage: 3.6 V
• Functions: grass trimming (edging) and hedge cutting
• Blade types: dedicated grass-trimmer blade and hedge-cutting blade
• Intended use: light garden maintenance and spot trimming
• Weight and dimensions: compact and lightweight design for easier handling

How to use

Fully charge the battery before the first use following the manufacturer’s charging instructions. Select and attach the appropriate cutting head for the task: the grass-trimmer blade for edging and turf tidying, or the hedge blade for trimming small shrubs. Hold the tool with a firm, comfortable grip and work with smooth, controlled passes; for edging, move along the border with the tip angled slightly into the grass, and for hedges use steady horizontal or vertical strokes depending on the shape. Keep the blades clean and free of debris, and switch off and remove the battery before performing any maintenance or blade changes.

What to consider before purchase

• Intended workload: suitable for light, occasional trimming rather than heavy or continuous use
• Battery life and charging: check expected runtime and charging time for your maintenance needs
• Cutting capacity: designed for small shrubs and soft growth, not for thick branches
• Ergonomics: compact size and weight may be preferable for tight spaces but offers less reach than telescopic models

Usage recommendations

For best results, perform short, regular maintenance sessions rather than infrequent heavy cuts. Use the grass-trimmer blade for clean edging after mowing, and the hedge blade for light shaping. Store the tool and battery in a dry place and ensure blades are sharpened or replaced as needed to maintain cutting efficiency.
