A lawn trimmer edger combo lets you handle string trimming and edging with one power head or one battery platform, which can cut down on storage space and battery swaps. The question most buyers face is whether a combo kit really edges as cleanly as a dedicated edger, and which model fits a yard of a given size. This guide compares five combo options from the Greenworks and BLACK+DECKER lines, based on listing specifications, brand reputation and common owner feedback. We have not tested these machines ourselves, so treat the notes below as a research summary rather than hands-on results.

Best for: Homeowners who want one platform for trimming edges and clearing clippings.

Pros
- Auto feed line reduces stopping to re-extend string

- Two batteries and charger included
- Hard-surface leaf blower function

The wider 13-inch trimmer path and the 40V platform point toward owners with bigger lawns and more edge length to cover. Extra spools included in the kit help when the string runs out mid-job.
Key specs

Buying Guide
Check whether the kit includes batteries and a charger
Some combo kits ship with batteries and charger, while others sell the power head alone. Read the bundle contents before you compare prices, because a missing battery can add a significant cost to the purchase. Confirm the battery voltage and platform too, since the same brand may use different systems across product lines.

Cutting path width
Trimmer heads are often listed in inches of cutting path. A 10-inch path works well in tight spaces, while 12 to 13 inches covers more ground per pass. Wider paths can be harder to control along curved beds, so match the width to the shape of your edges.

Battery platform and voltage
Higher-voltage platforms generally offer more power and can support heavier work, though runtime depends on amp-hour rating as well. Check whether you already own batteries from the same brand, because sharing a platform can save money over time. Look at the amp-hour figure in the listing, since a larger battery usually means longer sessions.

Blower airflow for cleanup
If you plan to use the blower for clearing clippings and debris, airflow measured in CFM matters. Higher CFM figures generally move more debris, but they also affect how far leaves and dust are pushed. Use the blower on hard surfaces away from windows and neighbors.

Auto feed and string handling
Auto feed heads release more string when you tap the head on the ground, which reduces stops for manual re-extension. Manual heads are simpler and lighter but need more attention during edging. Keep spare spools on hand, especially for larger properties.

Weight and handling
Edging involves holding the tool at an angle for long periods, so balance and weight affect comfort and accuracy. Lighter kits suit smaller yards and users with limited strength, while heavier kits may feel more stable on thick grass. Hold the tool before buying if you can.

Adjustability
Adjustable height or trimmer length helps you match the tool to the depth of the edge and the height of the grass. Settings that lock firmly are easier to use consistently. Check that adjustments are easy to reach and do not require tools for everyday changes.

FAQ
What is a lawn trimmer edger combo?
It is a single kit that pairs a string trimmer with an edging function, and often a blower or other attachment, using a shared motor or battery platform. Edging works by angling the trimmer head so the string cuts along the border of a lawn, bed or walkway.
Can a combo kit edge as cleanly as a dedicated edger?
Many owners find a string trimmer works well for light edging, though a dedicated wheeled edger with a blade typically produces a crisper vertical cut. Results depend on technique, grass type and how often you maintain the edge. For a deeper look, Difference Between Lawn Edger and Trimmer (2026): Which Should You Choose? covers this in detail.
Do these kits include batteries?
Some do and some do not. Check the bundle contents in each listing, since bundles differ in whether they include batteries, chargers or spare spools.
Which kit suits a small yard?
Compact kits with a 10- to 12-inch cutting path are usually easier to handle in small spaces. The BLACK+DECKER 20V MAX combo and the 3-in-1 kit are common choices for smaller lawns.
How often should I replace the trimmer string?
String wears faster on hard edges and when cutting thick weeds. Replace it when it becomes short or frayed, and keep spare spools on hand. Always follow the manufacturer’s instructions for the specific head.
Is it safe to use a string trimmer along edges?
Wear eye protection and closed shoes, keep bystanders and pets clear, and avoid hitting stones or metal edging, which can throw debris. For safety guidance on outdoor power equipment, consult the manufacturer’s manual and a qualified professional if you are unsure.
Conclusion
For most typical yards, the Greenworks 40V 12 in String Trimmer & 390 CFM Blower Combo offers a balanced mix of trimming, edging and cleanup. Buyers with compact spaces may prefer the BLACK+DECKER 20V MAX combo, which includes two batteries. Budget-minded shoppers who want three functions can look at the BLACK+DECKER 3-in-1 kit, while patio- and driveway-focused owners may favor the Greenworks 24V model with its higher airflow. Larger lawns with longer work sessions suit the Greenworks 40V 13 in combo. Match the kit to your cutting-path needs, battery platform and whether you plan to use the blower regularly.
