Does Dewalt Make a Weed Eater? Overview
Dewalt’s entry into the outdoor power equipment market began with the 20V Max platform, which shares batteries with the company’s extensive cordless drill and impact driver lineup. The 20V Max string trimmers are aimed at homeowners with small to medium yards, offering a lightweight design, variable speed trigger, and a bump‑feed head that advances line with a simple tap on the ground. In 2020 Dewalt expanded the portfolio with the 60V FlexVolt system, a higher‑voltage platform that can also run on 20V Max batteries thanks to its dual‑voltage architecture. The 60V FlexVolt trimmers target larger properties and professional crews who need longer run time, higher torque, and the ability to swap batteries across a broader range of tools such as chainsaws, blowers, and hedge trimmers.
Both families use brushless motors, which provide longer motor life, higher efficiency, and cooler operation compared to brushed designs. The cutting heads accept standard 0.080‑inch or 0.095‑inch line, and most models ship with a 13‑inch cutting swath that can be widened to 15 inches with an optional guard. Because the batteries are interchangeable within each voltage family, you can build a kit that matches your existing Dewalt investment, reducing the total cost of ownership.
Dewalt 20V Max String Trimmer
The flagship 20V Max model is the DCST920P1, a 13‑inch straight‑shaft trimmer that weighs just 7.5 pounds with a 5.0 Ah battery installed. It features a variable‑speed trigger that lets you feather the power for delicate edging or ramp up to full throttle for thick brush. The bump‑feed head is tool‑free; a quick tap on the pavement advances fresh line without stopping the motor. Runtime on a 5.0 Ah pack averages 45 minutes of continuous cutting, which is sufficient for most residential lawns up to a quarter acre.
Ergonomics are a strong point: the front handle rotates 180 degrees, allowing left‑ or right‑handed users to find a comfortable grip. The shaft is telescopic, extending from 57 inches to 63 inches, so you can adjust the length to your height and reduce back strain. The motor is rated at 4,500 RPM no‑load speed, delivering a clean cut through grass, weeds, and light saplings. Because the 20V Max platform includes over 200 tools, you can share batteries with drills, circular saws, and even the Dewalt 20V Max leaf blower for a complete yard‑care kit.
Dewalt 60V FlexVolt String Trimmer
The 60V FlexVolt lineup currently centers on the DCST970X1, a 15‑inch straight‑shaft trimmer that pushes the performance envelope for battery‑operated outdoor tools. With a 9.0 Ah FlexVolt battery the unit weighs about 10.2 pounds, still well under the weight of comparable gas trimmers. The brushless motor spins up to 6,200 RPM no‑load, delivering roughly 30 percent more torque than the 20V Max counterpart. This extra power translates into faster line speed, deeper cuts in heavy brush, and the ability to run a 0.095‑inch line at full throttle without bogging.
Runtime is a major selling point: a single 9.0 Ah pack can provide up to 70 minutes of continuous operation, and the dual‑voltage design means you can also run the trimmer on two 20V Max 5.0 Ah batteries in series if you already own them. The FlexVolt battery features a built‑in fuel gauge and a rapid‑charge capability that brings a depleted pack to 80 percent in about 45 minutes on the DCB118 fast charger. The trimmer also includes a variable‑speed trigger with a lock‑on button for extended runs, a rotating front handle, and a telescoping shaft that extends to 65 inches.
Key Differences Between 20V Max and 60V FlexVolt
Choosing between the two voltage families comes down to yard size, existing battery ecosystem, and budget. The table below summarizes the most important specifications side by side.
| Feature | 20V Max (DCST920P1) | 60V FlexVolt (DCST970X1) |
|---|---|---|
| Voltage | 20 V (single‑cell) | 60 V (dual‑voltage, runs on 20 V packs) |
| Motor Type | Brushless | Brushless |
| No‑Load RPM | 4,500 | 6,200 |
| Cutting Swath | 13 in (optional 15 in) | 15 in (standard) |
| Weight (with battery) | 7.5 lb (5.0 Ah) | 10.2 lb (9.0 Ah) |
| Runtime (typical) | 45 min (5.0 Ah) | 70 min (9.0 Ah) |
| Battery Compatibility | All 20V Max packs | FlexVolt 60V packs + two 20V Max packs in series |
| Price Range (tool only) | $179‑$199 | $279‑$299 |
| Target User | Homeowner, small‑to‑medium yard | Large property, professional crew |
As the table shows, the 60V FlexVolt model offers a wider cutting swath, higher RPM, and longer runtime, but it comes at a higher upfront cost and a modest weight increase. If you already own a collection of 20V Max batteries, the 20V Max trimmer lets you leverage that investment immediately. Conversely, if you plan to add other FlexVolt tools — such as a 60V chainsaw or a 60V blower — the 60V trimmer becomes the hub of a high‑performance cordless ecosystem.

How to Choose the Right Dewalt Trimmer for Your Yard
Follow these steps to match a Dewalt trimmer to your specific needs.
- Measure your lawn area. Walk the perimeter and note the square footage. Yards under 5,000 sq ft usually fit the 20V Max runtime; larger areas benefit from the 60V FlexVolt endurance.
- Assess vegetation density. Light grass and weeds are fine for 20V Max. Thick brush, woody stems, or overgrown fields demand the extra torque of the 60V model.
- Inventory existing batteries. Count how many 20V Max packs you own and their amp‑hour ratings. If you have multiple 5.0 Ah or higher packs, the 20V Max trimmer may be the most cost‑effective choice.
- Consider future tool purchases. If you anticipate buying a cordless chainsaw, hedge trimmer, or blower, the FlexVolt platform lets you share high‑capacity batteries across all tools.
- Set a budget. Factor in the cost of the tool, at least one battery, and a charger. A 20V Max kit (tool + 5.0 Ah battery + charger) typically runs $250‑$280. A 60V FlexVolt kit (tool + 9.0 Ah battery + fast charger) runs $420‑$460.
- Test ergonomics if possible. Visit a local dealer, hold each model, extend the shaft, and operate the trigger. Comfort over a 30‑minute session can outweigh raw specs.
- Read warranty and service terms. Both lines carry a 3‑year limited warranty on the tool and a 2‑year warranty on batteries. Verify local service center availability.
- Make the purchase. Buy from an authorized retailer to ensure genuine Dewalt batteries and full warranty coverage.
Setting Up Your Dewalt Trimmer
Proper initial setup ensures safe operation and maximum performance. The steps below apply to both voltage families; minor differences are noted.
- Charge the battery fully. Insert the pack into the compatible charger (DCB115 for 20V Max, DCB118 for FlexVolt) and wait for the green indicator. A full charge maximizes first‑run runtime.
- Attach the cutting head. Align the head’s drive shaft with the motor output, push until the locking tab clicks. For the bump‑feed head, ensure the line spool is seated correctly and the line exits the eyelet.
- Install the line. Use 0.080‑inch line for general grass; switch to 0.095‑inch for heavier brush. Wind the line onto the spool following the arrow direction printed on the head. Leave about 6 inches of line protruding on each side.
- Adjust the shaft length. Loosen the telescoping collar, extend or retract the shaft to a comfortable height (typically elbow height when standing upright), then tighten the collar securely.
- Set the front handle. Rotate the handle to the preferred side (left or right) and lock it in place. The handle should allow a natural wrist angle.
- Insert the battery. Slide the pack into the tool’s battery bay until the latch clicks. Verify the battery fuel gauge shows a solid charge.
- Perform a safety check. Ensure the guard is attached, the line is not tangled, and the trigger moves freely. Wear eye protection, hearing protection, long pants, and closed‑toe shoes.
- Test run. Squeeze the trigger gently, let the motor spin up, and tap the head on pavement to advance line. Confirm smooth operation before tackling the yard.
Maintenance Tips for Longevity
Regular upkeep keeps your Dewalt trimmer running like new for years. Incorporate these habits into your routine.
- Clean after each use. Remove grass clippings, dirt, and debris from the guard, motor vents, and cutting head with a soft brush or compressed air. Moisture left on metal parts can cause corrosion.
- Inspect the line regularly. Replace worn or frayed line before it breaks mid‑cut. Keep a spare spool in your tool bag.
- Lubricate the shaft. Apply a light coat of silicone spray to the telescoping shaft threads every 20 hours of operation to prevent binding.
- Check battery health. Store batteries at 40‑60 % charge in a cool, dry place. Avoid leaving them on the charger for weeks at a time.
- Tighten fasteners. Periodically verify that the guard bolts, handle lock, and head locking tab are snug. Vibration can loosen them over time.
- Sharpen or replace the blade (if using a blade attachment). A dull blade increases motor load and reduces battery life.
- Update firmware (if applicable). Some newer FlexVolt tools support Bluetooth connectivity via the Dewalt Tool Connect app; check for firmware updates that can improve motor management.
- Seasonal deep clean. At the end of the mowing season, disassemble the cutting head, soak the spool in warm soapy water, dry thoroughly, and re‑grease the drive shaft with a marine‑grade grease.
Common Issues and Troubleshooting
Even reliable tools can hiccup. Here are the most frequent problems and quick fixes.
- Trimmer won’t start. Verify the battery is fully seated and charged. Check the trigger safety lock; some models require the lock‑off button to be pressed before the trigger engages.
- Line does not advance. Ensure the bump‑feed head is not clogged with debris. Tap the head firmly on a hard surface; if line still won’t feed, open the head and re‑wind the spool correctly.
- Motor overheats and shuts down. This usually indicates excessive load — thick brush or a dull line. Reduce cutting width, switch to a heavier line, or let the motor cool for a few minutes.
- Reduced runtime. Battery capacity degrades with age. If runtime drops below 50 % of spec, consider a new pack. Also confirm you’re not using a low‑amp‑hour battery on a high‑draw tool.
- Excessive vibration. Loose guard or handle bolts are the usual culprits. Tighten all fasteners to the torque values in the manual (typically 5‑7 Nm).
- Battery indicator shows error code. Consult the Dewalt Tool Connect app or the manual for the specific code. Common codes relate to temperature extremes or cell imbalance.
Accessories and Attachments
Expanding the versatility of your Dewalt trimmer is easy with the following add‑ons.
- Edger attachment. Converts the trimmer into a dedicated lawn edger with a vertical blade for crisp sidewalk lines.
- Brush cutter blade. A metal 3‑tooth blade for tackling saplings, thick brush, and small trees up to 2 inches in diameter.
- Extended reach shaft. Adds 12 inches of length for high hedges or hard‑to‑reach areas without a ladder.
- Shoulder strap. Distributes weight across the torso, reducing fatigue during long sessions.
- Battery holster. Mounts on the shaft to keep a spare pack within arm’s reach.
- Protective guard kit. Includes a wider debris shield and a line‑cutting knife for clean line trimming.
All accessories use the same quick‑connect interface, so swapping takes seconds and requires no tools.
