A string trimmer is an invaluable tool for putting the finishing touches on a well-manicured lawn. It excels at tackling areas a lawn mower can’t reach, such as around fences, trees, garden beds, and along walkways. However, achieving a clean, even cut with a string trimmer requires more than just turning it on and swinging it around. With the right technique and a few key tips, you can transform your trimming results from ragged to pristine, ensuring your yard looks its absolute best.
1. Safety First, Always
Before you even think about starting your trimmer, prioritize safety. This is non-negotiable for preventing accidents and injuries.
- Wear Protective Gear: Always wear safety glasses or goggles to protect your eyes from flying debris. Long pants, sturdy closed-toe shoes or boots, and gloves are also highly recommended.
- Clear the Area: Before you begin, walk through the area you intend to trim and remove any rocks, sticks, toys, or other objects that could be thrown by the rotating line.
- Maintain Distance: Keep bystanders, especially children and pets, at a safe distance (at least 50 feet) from your work area.
2. Use the Right Trimmer and Line
The quality of your tools directly impacts the quality of your cut.
- Match Trimmer to Task: For light trimming and edging, a lightweight electric or battery-powered trimmer is often sufficient. For dense weeds or larger areas, a more powerful battery or gas-powered model will be more effective.
- Correct Line Diameter: Use the string line diameter recommended by your trimmer’s manufacturer. Using line that’s too thin will cause it to break frequently, while line that’s too thick can strain the motor.
- Fresh, Conditioned Line: Old, dry line is brittle and breaks easily. Store new line in a cool, dry place. Some pros even recommend soaking new line in water for 24 hours before use to make it more flexible and durable.
- Properly Loaded Line: Ensure the line is wound tightly and evenly on the spool. Overlapping or loose winding can lead to tangles and feeding issues.
3. Master the Cutting Technique
How you hold and move the trimmer is crucial for an even cut.
- Maintain a Consistent Angle: Hold the trimmer head parallel to the ground for general trimming. Avoid tilting it too much, as this can create scalped areas or uneven cuts.
- Use the Tip of the Line: The very tip of the string line does the best cutting. Avoid trying to use the entire length of the line, as this reduces efficiency and can bog down the motor.
- Swing in an Arc: Instead of chopping, swing the trimmer in a smooth, consistent arc from side to side. Overlap each pass slightly to avoid missing spots.
- Feed Slowly and Steadily: Don’t rush. Move the trimmer at a steady pace, allowing the line to do its job. Rushing can lead to uneven cuts and more line breakage.
- “Feathering” for Edging: When edging along a driveway or sidewalk, hold the trimmer head vertically. Use a gentle, “feathering” motion, making light passes to gradually create a clean line, rather than trying to cut deep all at once. An edging wheel (if your trimmer has one) can greatly assist here.
4. Work in Sections and Be Mindful of Obstacles
Approach your trimming tasks systematically.
- Divide and Conquer: For larger areas, work in manageable sections. This helps maintain focus and prevents fatigue.
- Trim Away from Obstacles: When trimming around trees, fences, or other obstacles, approach them carefully. Trim away from the obstacle to avoid damaging the tree bark or property. Consider installing tree rings or landscape edging to create a buffer zone.
- Adjust for Different Heights: If you need to trim different grass heights, adjust your technique. For very tall grass, start by cutting off the top section, then lower the trimmer for a second pass.
5. Regular Maintenance for Optimal Performance
A well-maintained trimmer performs better and lasts longer.
- Clean the Head: After each use, clean grass clippings and debris from the trimmer head and shaft. Built-up debris can affect balance and line feeding.
- Sharpen the Cut-Off Blade: The small blade on the trimmer guard that cuts excess line can become dull. Keep it sharp for proper line management.
- Check for Loose Parts: Periodically inspect the trimmer for any loose screws, bolts, or worn components.
By incorporating these tips into your trimming routine, you’ll not only achieve a cleaner, more even cut but also extend the life of your string trimmer and make your yard work more efficient and enjoyable.
