As the name suggests, a hedge trimmer is useful for giving hedges and plant fences a more aesthetic shape. Whether electric or gas-powered, corded or battery-operated, this tool can be telescopic or mounted on a pole to facilitate the maintenance of tall hedges.
Hedge trimmers differ in their motorization and power source.
- Corded electric models are appreciated for their affordable price and lightness. They have a power range from 400 W to 700 W.
- Battery-powered electric models appeal for their maneuverability. They can be equipped with an 18 V, 36 V, or 56 V Li-ion battery depending on their power.
- Gas-powered versions are equipped with a 2-stroke or 4-stroke engine. Their power ranges from 0.4 HP to 1.4 HP. These devices are suitable for professional use.
Several parameters should be considered when choosing a hedge trimmer.
- The cutting length depends on the blade length, which ranges between 40 cm and 75 cm. The choice depends on the width of the hedges to be trimmed, the dexterity of the user, and their physical strength, because the length of the blade influences the weight of the tool.
- Blades can be single-action or double-action. Double-edged versions are also available. It should be noted that the spacing between the teeth depends on the diameter of the branches to be cut.
- For tall hedges, the user can opt for a pole or telescopic device.
Some tips are useful for the maintenance of a hedge trimmer:
- regular lubrication of the blades is recommended to optimize its operation;
- the blades are not washable with water but can be cleaned with denatured alcohol in the presence of sap;
- a check of the oil level and the condition of the spark plug is necessary for gas-powered models.
Ultimately, the choice of a hedge trimmer depends on its use (occasional or professional), the height of the hedges, the diameter of the branches to be cut, and the user's physical abilities.
