A best cordless trimmer and edger combo is one battery tool that trims grass and then edges a walkway, usually by turning the head or by adding a wheel that rides on the edge. Most people searching this phrase want one machine that does both jobs without a second tool. The practical answer is to match the battery first, then check the cut width, the weight and the edging method. This roundup covers the seven cordless combos in our catalog record for this keyword. Each entry uses only what its listing states about battery, cut width, weight, speed, line feed and warranty, and each one names what the listing leaves open.

Quick answer

• Match the battery first. Every listing in this set names a battery platform, but only one puts a battery and charger in the box.
• Edging works in two ways across these listings: the head turns 90 degrees, or a wheeled edger rides along the edge. Some listings describe one method, and a few describe both.
• Cut width runs from 12 inches to 16 inches. The Bosch listing gives the widest figure at 16 inches, and the DEWALT listing gives 15 inches.
• Where a listing gives a weight, the figures run from about 4 pounds to 12.7 pounds. The two heaviest listings are also the two with the widest cut.

Start with the battery you own

The battery platform decides what you can run without a second purchase. The listings name six battery platforms: 60V MAX FlexVolt, DeWalt 20V MAX, 24V, Bosch 18V, Makita 18V and Milwaukee M18. The listings name different voltages, so a 20V pack and an 18V pack are not the same platform. A listing that names one platform does not tell you that it works with another, so the platform you already own is the first filter, before any feature comparison.

Only one listing puts power in the box. The Greenworks trimmer and blower kit lists one 2.0 Ah battery and a 30W USB-C charger. The other six are tool-only, bare, or say the battery and charger are not included, so each of those needs a compatible battery and charger bought separately.

Listing	Platform named in the listing	Battery and charger in the box
DEWALT DCST970B	60V MAX FlexVolt	No, listed as a bare tool
HEINPRO trimmer	DeWalt 20V MAX	No
Greenworks 24V trimmer and blower kit	Greenworks 24V	Yes, one 2.0 Ah battery and a 30W USB-C charger
Bosch GRT18V-40N	Bosch 18V	No, sold separately
worksky trimmer	DeWalt 20V Max	No battery
MtiolHig 3-in-1	Makita 18V	No, not included
SHOHO trimmer	Milwaukee M18	No, not included

For a closer look at the DEWALT FlexVolt model on its own, see our DEWALT FlexVolt string trimmer post. For a head-to-head of two string trimmer lines, see Greenworks versus EGO Power+ string trimmers.

The Greenworks listing is a trimmer and leaf blower kit. It is the only entry in this set that bundles a second tool. That suits a buyer who wants both a trimmer and a blower from one battery, and it does not suit a buyer who wants an edger, because the listing names no edging mode.

What the edging head does in each listing

Edging needs the head to sit square to a walkway edge, and the listings describe three methods for getting there: a head that turns 90 degrees, a wheel that holds the head at a steady height, or a conversion that changes the trimmer into an edger. The listings differ in how much they say about each one.

• DEWALT calls the unit an edger/trimmer in one bullet, but its listing does not describe a wheel, a head turn or an edger attachment. Treat its edging claim as unverified until the full product page confirms it.
• HEINPRO says you can rotate the cutting head 90 degrees to switch to a wheeled edger.
• Greenworks describes a trimmer and blower kit and names no edging mode.
• Bosch says the dual-function hand grip and the toolless adjustable D-handle let you move from trimming to edging.
• worksky names three modes, trimmer, edger and mower, and says the conversion is simple.
• MtiolHig says it converts to edge sidewalks, and it adds a 75-degree tilting head for reaching slopes.
• SHOHO says the unit converts into a precision trimmer, an upright wheeled edger or a mini lawn mower.

The practical difference is what each listing says guides the head. HEINPRO and SHOHO describe a wheeled edger, and WORX says its rubberized twin wheel set supports and guides the edger. HEINPRO’s other method is a 90-degree head turn. Each listing describes a method, not a result. None of these listings reports how clean the finished edge looks, so the method tells you what the tool is built to do, not how well it does it.

Cut width, weight and speed side by side

Cut width tells you how much grass one pass clears. Weight tells you how long you can keep the head moving before your arms tire. Speed is a motor figure on the listing, and it is not a measured cut result. The table below shows what each listing states. Where a listing gives two figures, both are shown.

Listing	Cut width	Weight	Motor speed
DEWALT DCST970B	15 in	12 lb	not stated
HEINPRO trimmer	12 in	4.2 lb	not stated
Greenworks kit	12 in	4.08 lb, trimmer without battery	not stated
Bosch GRT18V-40N	16 in	12.7 lb	up to 5,300 RPM
worksky	12 in	not stated	7,000 rpm
MtiolHig	12 in in the specifications, 11 in in a bullet	6 lb in the specifications, 5.5 lb in a bullet	4,800 rpm in the specifications, 8,500 rpm in a bullet
SHOHO	12 in	not stated	9,000 rpm

Two calculations from these figures show the trade-off. 16 divided by 12 is about 1.33, so the Bosch listing’s cut is roughly a third wider than the 12-inch cuts most of the others state. The same listing gives 12.7 pounds, and 12.7 minus 4.2 equals 8.5 pounds, which is the gap between it and the HEINPRO listing. A wider cut covers more ground per pass, but the extra weight is paid for on every stroke.

The speed figures are listing numbers, not measured ones. A higher rpm on one listing does not prove a faster cut than a lower rpm on another, so this article does not rank the motors by speed.

Line feed and spool changes

Five of the seven listings name an automatic line feed. HEINPRO says each trigger press releases about 0.5 inch of line. SHOHO says it releases about 0.4 inch each time the trimmer starts, provided enough line remains on the spool. Greenworks and worksky name automatic feed without giving an amount, and Bosch describes a Pro-Tap spool that adjusts the line automatically. DEWALT uses a bump-feed head with a 0.08-inch dual line installed. The MtiolHig listing names 18 spare lines of 0.11 inch and does not describe its feed method.

Feed amounts are small, and they add up. At 0.4 inch per start, ten starts would release about 4 inches of line, which is worth knowing before you judge how much line a run will use. The Virginia Tech powered hand tools guide notes that automatic-feed and bump-feed trimmers can release more string than you expect, and that this raises the chance the string strikes the operator. Keep that in mind when you start a new run along a fence or wall.

Safety and battery handling before you edge

Trimmers throw debris. The Virginia Tech and Texas A&M extension guides both say that string trimmers can throw stones, sticks and other objects at high speed. Clear glass, limbs, rocks and trash from the work area before you start. The same guides recommend eye and ear protection, and the University of Florida IFAS lawn equipment page says the same for lawn tools in general. Keep bystanders, children and pets well outside the work area; the Virginia Tech guide uses a 50-foot radius as its example.

Keep the string head below waist level and avoid reaching past your balance. Both extension guides also say to keep guards and string guides in place, and not to remove them.

Electric models need the usual checks. The Texas A&M guide says to inspect extension cords for cuts, nicks, scrapes and exposed wire, to replace damaged cords right away, and not to run an electric trimmer in wet conditions or around puddles. The Virginia Tech guide says to unplug an electric trimmer before inspecting it or changing the line. A cordless model has no cord, so the equivalent step is to take the battery out before you change the line. The extension guides do not address cordless units directly, so treat that step as general practice.

Battery handling matters for every unit in this set. The U.S. EPA guidance on used lithium-ion batteries says these batteries should not go in household trash or recycling bins, and they should go to a separate recycling or household hazardous waste collection point. EPA recommends taping the battery terminals and placing each battery in its own plastic bag to prevent fires, and it warns that even used batteries can have enough energy to injure or start a fire. EPA names Earth 911 and Call2Recycle as two ways to find a recycler.

Metal-blade edgers carry a different hazard. The Virginia Tech guide says they can cut through underground objects, splinter concrete and throw sparks. The listings in this set are string units, not metal-blade edgers, so that particular hazard is not the main one for them.

Which combo fits which yard

• A small front walk with many corners: the HEINPRO trimmer, at 4.2 pounds in its listing, or the MtiolHig, whose listing says the shaft folds down to 28 inches for storage.
• A long straight edge or a wide strip: the Bosch listing, if you already own Bosch 18V batteries and accept a 12.7-pound tool.
• Ready to start with a battery already in the box: the Greenworks kit, which lists one battery and a charger and adds a blower.
• You already own DeWalt 20V MAX batteries: the HEINPRO or the worksky, which names DeWalt 20V Max as its compatible platform but includes no battery.
• You already own Makita 18V, Milwaukee M18 or 60V MAX FlexVolt batteries: the MtiolHig, the SHOHO, or the DEWALT DCST970B, respectively.

Choose on the battery first, then the edging method you want, then the width. The seven cards below give the choice points for each listing.

The seven listings compared

Each card uses the features its listing states. The pros and cons come from the listing text or from the figures in the table above, and each affiliate link goes to that listing.

How we chose

We started from the seven listings in the catalog record for this keyword. We did not add products to the set, and we did not drop any from it, so the group you see here is the full group the catalog record holds for this keyword. We did not use price, availability or customer feedback data when choosing.

Each listing was checked against four points that the listing itself states. It must be a cordless string trimmer or trimmer and edger, it must name a battery platform, it must give a cut width, and it must describe an edging or conversion method. Five of the seven name a specific edging or conversion method. The DEWALT listing uses the phrase edger/trimmer without describing a method, and the Greenworks kit names no edging mode. Both are included because they are cordless trimmers in the catalog record for this keyword, and both are weaker fits for edging.

Each card needs at least one pro and one con from its own listing, plus a skip-if condition. Where a listing contradicts itself, the card says so instead of picking one figure. The MtiolHig card is the clearest example.

What we could not verify

• Runtime. Only the MtiolHig listing gives a runtime range, 30 to 55 minutes with a 4 Ah or larger battery. The other listings give no runtime in minutes, so this article cannot compare how long each battery lasts.
• Edge quality. None of the listings reports the finished edge, so we cannot say which head leaves the cleanest line along a walkway.
• Durability and motor life. The Bosch listing uses the phrases durable and aluminum motor housing, and the HEINPRO listing describes dual safety switches. Neither gives wear or life data, so this article does not rank durability.
• Noise and vibration. None of the listings in this set states a noise level or a vibration figure, so those comparisons are not possible from the data.
• MtiolHig. Its specification table and its bullets disagree on motor speed, on weight and on cut width. This article reports both figures and does not choose one.
• Battery compatibility. A listing names a platform, but it does not confirm that every battery model in that platform will fit. Check the battery model in the listing before you order, and do not assume that two names in the same family are interchangeable.
• Warranty. Four listings give a warranty term: DEWALT and Greenworks state three years, Bosch states five years and SHOHO states one year. The HEINPRO, worksky and MtiolHig listings do not state a term in the data we used.
• Real-world cutting width. The cut width figures are what each listing states. They are not measured results from any unit in this article.

FAQ

Is a cordless trimmer and edger combo the same as a trimmer with an edger attachment?

Not always. The HEINPRO listing says the head rotates 90 degrees to become a wheeled edger, and the SHOHO listing describes an upright wheeled edger. The DEWALT listing calls its unit an edger/trimmer in one bullet but does not describe how the edging works. Read the method line in each listing before you decide which style you want.

Do I need to buy a battery for these combos?

Six of the seven listings say the battery is not included, bare, or sold separately. The Greenworks kit is the only one that lists a battery and charger in the box. If you already own a battery, match its platform to the listing before you compare any other feature.

Is a 16-inch cut always better than a 12-inch cut?

A wider cut covers more ground on each pass, and the Bosch listing’s 16 inches is about a third wider than the 12-inch listings. The same listing is also the heaviest, at 12.7 pounds. For a long straight edge a wide cut can help. For a small yard with many corners, a 12-inch listing with a lighter head may be the better fit.

Can a DeWalt battery run the DEWALT trimmer and the HEINPRO trimmer?

The DEWALT listing names a 60V MAX FlexVolt platform. The HEINPRO and worksky listings name DeWalt 20V MAX batteries. The listings do not say the two platforms are interchangeable, so check the battery model named in each listing before you buy.

How should I dispose of an old lithium-ion trimmer battery?

Do not put it in household trash or recycling bins. Take it to a separate recycling point or a household hazardous waste collection location. Tape the terminals, put the battery in its own plastic bag, and use a recycler finder such as Earth 911 or Call2Recycle to locate a drop-off point.

Bottom line

Match the battery you already own, then choose the edging method you prefer, then compare the cut width and weight. If a listing’s battery does not match your tools, skip that listing before you compare anything else.
