The Ultimate Buying Guide for Your Dewalt Battery String Trimmer
Choosing the right Dewalt battery string trimmer makes yard work much easier. These tools offer freedom from gas fumes and tangled cords. This guide helps you pick the best one for your needs.
Key Features to Look For
When shopping for a Dewalt trimmer, check these important features first. They tell you how well the trimmer will work.
1. Battery Platform Compatibility
Dewalt uses a powerful battery system. Make sure the trimmer works with the batteries you already own (like the 20V MAX or FLEXVOLT systems). If you buy a “bare tool,” you need to already have a compatible battery and charger. This saves money.
2. Cutting Width (Line Diameter)
The cutting width matters for speed. Wider heads cut more grass in one pass. Most home-use models offer 13 to 16 inches. A 15-inch cut is often a good balance for speed and maneuverability.
3. Speed Settings (Variable Speed Trigger)
Good trimmers let you control the speed. Low speed is great for edging or trimming delicate areas. High speed gives you maximum power for thick weeds. Always look for a variable speed trigger.
4. Feed Mechanism
How the trimmer releases new cutting line is crucial. Bump feed requires you to tap the head on the ground. Auto-feed systems release line automatically. Manual feed requires you to stop and adjust the line. Auto-feed usually offers the best user experience.
Important Materials and Build Quality
The materials used affect how long your trimmer lasts and how heavy it feels.
- Shaft Material: Look for aluminum or fiberglass shafts. These materials are strong but lightweight. Plastic shafts break easily.
- Housing: The motor housing should be durable plastic, often reinforced. Good sealing protects the motor from dirt and moisture.
- Cutting Head: The head should be tough plastic or metal where the line comes out. This area takes the most impact.
Factors That Improve or Reduce Quality
These details separate a basic trimmer from a professional-grade tool.
Quality Boosters:
High-quality Dewalt trimmers include features like brushless motors. Brushless motors use less battery power and last much longer than brushed motors. Also, look for built-in line cutters on the guard; this small feature saves time.
Quality Reducers:
Cheap plastic gears inside the head wear out quickly. If the tool feels very light, it might mean too much plastic was used. Trimmers without proper weather sealing fail faster when used in damp grass.
User Experience and Use Cases
Think about where you will use your trimmer most often.
For Small Yards:
A lighter, shorter trimmer with a 13-inch cut path works well. Battery life is less of a concern if you only trim for 15 minutes.
For Large Properties:
You need high power and long battery run time. Choose a model with a 16-inch cut width and a high-capacity FLEXVOLT battery. These models handle thick brush better.
Ergonomics:
Test how the weight feels. Can you easily adjust the handle position? A well-balanced tool reduces arm fatigue significantly during long trimming sessions.
10 Frequently Asked Questions (FAQ) About Dewalt Battery String Trimmers
Q: What is the main benefit of a Dewalt battery trimmer?
A: The main benefit is freedom. You do not need gas, oil, or extension cords. They start instantly with the press of a button.
Q: Are Dewalt trimmers powerful enough for thick weeds?
A: Yes, especially the models using the FLEXVOLT battery system. They provide power close to gas models when needed.
Q: How long does the battery usually last?
A: Battery life depends on the Amp-hour (Ah) rating and the speed you use. A standard 5.0Ah 20V MAX battery lasts about 30 to 50 minutes of continuous trimming.
Q: Can I use any Dewalt battery with any Dewalt trimmer?
A: Most 20V MAX tools accept all 20V MAX batteries. Always check the manual, especially if you are looking at the heavier-duty FLEXVOLT tools, as they sometimes require specific batteries.
Q: What is a ‘bare tool’ purchase?
A: A bare tool purchase means you only get the trimmer itself. You do not get the battery or the battery charger.
Q: How do I keep the cutting line from breaking too much?
A: Use the correct line diameter specified by Dewalt. Also, reduce your speed when trimming near hard objects like concrete fences.
Q: What is the difference between a straight shaft and a curved shaft?
A: Straight shafts offer better reach under bushes and are generally more durable. Curved shafts are lighter and sometimes easier to handle for very small jobs.
Q: Do these trimmers require maintenance?
A: Yes. You must keep the battery terminals clean. You should also occasionally clean debris from the motor vents.
Q: Can I use this trimmer to edge my lawn?
A: Many Dewalt models feature an adjustable head that lets you pivot the trimmer 90 degrees. This allows you to easily switch from trimming to edging along sidewalks.
Q: Are replacement parts easy to find?
A: Because Dewalt is a major brand, replacement parts like cutting heads, guards, and spools are generally easy to find online and at hardware stores.
