Best Lawn Mower With Weed Eater Attachment Kits
As an Amazon Associate we earn from qualifying purchases.
A lawn mower with weed eater attachment is usually a single power head that takes a detachable mower deck on one end and a string trimmer head on the other. You mow with the deck fitted, then remove it or switch the head to trim along fences, edge walks and reach the grass a push mower leaves behind. The combo format suits small and medium yards, tight corners and owners who want one motor and one battery platform instead of two machines. This guide compares four combo units from the product group, using only the facts each listing states, and explains how to decide between corded and cordless versions.
Quick answer
- For a corded setup with a 12-inch deck, the BLACK+DECKER electric 3-in-1 combo lists a 6.5 amp motor and an automatic feed spool.
- For a cordless setup with a 12-inch deck, the BLACK+DECKER 20V MAX combo lists two lithium-ion batteries and a charger in the kit.
- For a cordless 18.9-inch model with two 4.0Ah batteries, the Gisam YL-30 lists three interchangeable trimmer blades and a 12-inch cutting width.
- For the lightest option, the SmartGiant 4-in-1 unit lists about 7 pounds and a telescoping shaft from 34.6 to 51.2 inches.
What a combo unit can and cannot do
The main trade-off is capacity. A combo unit’s deck is smaller than a dedicated walk-behind mower, and the trimmer head works on the same drive as the mower. The listings in this group describe 12-inch cutting widths for the BLACK+DECKER and Gisam units, and the SmartGiant listing describes a 6-inch cutting width for its trimmer and mini mower function. A combo is a good fit for a small lawn, a narrow side yard or a patch the big mower cannot reach. It is less suited to a large open lawn, where a full-size mower will finish the job in fewer passes.
The other point is that an attachment setup changes the handling. A combo with a wheeled deck is heavier at the front and balances differently than a trimmer alone. The listings describe wheels, a pivoting handle and adjustable height as ways to manage that weight. Plan for a short session at first, and check the balance before you commit to a long mowing job.
How to choose between corded and cordless
Corded units
The BLACK+DECKER BESTA512CM is a corded electric unit. Its listing gives a 6.5 amp motor with POWERDRIVE transmission, a 12-inch cutting width and a listed speed of up to 8000 RPM. A cord gives steady power and removes battery charging from the routine. The tradeoff is the cord itself: you need an outlet within reach of the work area and a plan for managing the line. The listing includes a cord retention system that the listing says helps prevent accidental disconnects.
Cordless units
The BLACK+DECKER MTC220 is a battery-powered 3-in-1 unit. The listing includes two LBXR2020 20V MAX lithium-ion batteries, a charger, a detachable mower deck, a trimmer and edger, a guard, an auxiliary handle and an AF-100 spool. The Gisam YL-30 uses two 4.0Ah batteries and a 12-inch cutting width, and the SmartGiant unit uses a single lithium-ion battery in its listing with a shorter runtime per charge. Cordless units remove the cord problem, but runtime is the limit, so check the battery count in each listing before you choose.

The four options, one by one
1. BLACK+DECKER Electric Lawn Mower, Weed Eater and Edger 3-in-1 Combo (BESTA512CM)
This corded unit is the one in the group with a clear electric power spec. The listing describes a 6.5 amp motor with POWERDRIVE transmission for thick grass and weeds, an automatic feed spool that the listing says allows uninterrupted trimming, and a 12-inch cutting width. The kit includes the BESTA512 string trimmer, an MTD100 detachable mower deck, an AF-100 spool, an auxiliary handle and a guard. The trimmer head rotates to convert the unit into a wheeled edger. The listing states a 2 year limited warranty and a weight of 9.9 pounds. Its cutting height is listed at 1.6 inches. This is the choice for a corded yard with an outlet close by.
2. BLACK+DECKER Weed Eater, Lawn Edger and Cordless Lawn Mower 3 in 1 Combo (MTC220)
The MTC220 is the cordless version of the BLACK+DECKER line. Its listing includes two LBXR2020 20V MAX lithium-ion batteries, a charger, the MTD100 detachable mower deck, the AF-100 spool, an auxiliary handle, a guard and the MTC220 trimmer and edger. The listing says the removable wheeled deck turns the unit into a small lawn mower, and that the pivoting handle and adjustable deck height help with control. It describes PowerDrive transmission that is meant to prevent bogging in dense grass. The listing states a 12-inch cutting width, a weight of 9.9 pounds and a 2 year limited warranty. It is a practical option for a homeowner who wants a battery platform with spare capacity from two batteries.
3. Gisam 18.9-inch Cordless Lawn Mower, String Trimmer and Wheeled Edger 3-in-1 Combo (YL-30)
The YL-30 is the largest cutting width in this group at 12 inches on the mower, and the listing describes a brushless motor and two 4.0Ah batteries included in the box. It has three interchangeable blades: a string head for regular lawns, metal blades for heavier weeds, and an alloy saw blade for shrubs. The listing gives three cutting height levels and a 20 to 80 degree angle adjustment on the telescopic shaft. It also says the built-in safety lock helps avoid accidental startup. One point to note: the listing says the circular saw blade is not compatible with the lawn mower base, and that the base must be fully removed before using the saw blade. The listing does not state a warranty term. The YL-30 suits an owner who wants a cordless unit with more than one trimmer blade type.
4. SmartGiant 4-in-1 Cordless Weed Wacker with Wheels and Mini Lawn Mower (XC-009)
This unit is the lightest option in the group. The listing gives a weight of 7 pounds, a telescoping shaft from 34.6 to 51.2 inches, and a head that rotates from 0 to 90 degrees for edging driveways and reaching under fences. It describes four uses: string trimming, brush cutting up to about 1 inch of saplings, a mini lawn mower function for patches, and edging. The kit listing includes two batteries, a charger, a circular saw blade, hex blades, plastic blades, nylon line, two removable wheels, goggles, gloves and a grass deflector. The listing says the battery delivers 120 to 180 minutes of trimming. It also states a 12-month warranty and a dual safety lock on the trigger. The listing describes a 700W motor and 20000 RPM speed. It is best for a homeowner who wants a light tool for seniors or smaller hands, and who does not need a full-width mower deck.
Review: the BLACK+DECKER MTC220 in more depth
The MTC220 is the most complete cordless combo in this set, so it deserves a closer read. Its listing gives you the full set of parts: the trimmer and edger, the detachable mower deck, two lithium-ion batteries, a charger, an auxiliary handle, a guard and the AF-100 spool. The listing describes the unit as a 3-in-1 tool because you can switch between a push mower, a trimmer and an edger with one motor.
In practice, the deck is the part to check. The listing describes the removable wheeled deck as a way to build a small mower for slopes, tight spaces and areas a walk-behind mower cannot easily reach. The 12-inch cutting width is a clear limit for a larger lawn, so the MTC220 is most useful as a second tool or for a small yard. The adjustable deck height and the pivoting handle are listed as the main control features.
The listing’s PowerDrive transmission is described as a way to avoid bogging down in dense grass and weeds. We cannot confirm how that feels in a particular lawn, so read it as the manufacturer’s stated design rather than a measured result. The AFS automatic feed spool is listed as keeping the trimmer running without stopping for line adjustments. That matters for edging work, where constant stops slow the job.
The listing’s warranty is a 2 year limited term, and its weight is 9.9 pounds. Those two facts, plus the two included batteries, are the strongest reasons to choose this unit over a bare trimmer. If you already own a compatible 20V MAX battery platform, the listing does not say whether its batteries work with other tools, so check that before you assume the battery is interchangeable.
Close alternatives in this group
If the MTC220 is too small, the Gisam YL-30 gives the same 12-inch width with a different blade set and an 18.9-inch footprint in the title. If the MTC220 is too heavy or too corded for your yard, the SmartGiant unit is lighter and has a different battery setup. The BESTA512CM is the choice when you want a corded motor and do not want to manage batteries at all.
Sizing and fit: what the listings say
Most decisions in this group come down to three numbers: the cutting width, the weight and the trimmer reach. The BLACK+DECKER units and the Gisam unit share a 12-inch cutting width. The SmartGiant unit is the narrowest, with a 6-inch cutting width for its trimmer and mini mower function, and it is the lightest at about 7 pounds. The telescoping shaft on the SmartGiant unit adjusts from 34.6 to 51.2 inches, which the listing says fits users from about 5 feet to 6 feet 4 inches.
The weight of the BLACK+DECKER units is 9.9 pounds in their listings. The Gisam listing does not state a weight in the bullets, so compare the product dimensions and a physical test in a store if the weight matters to you. For shorter reach or a tight corner, the SmartGiant shaft and rotating head are useful. For a longer job, the 12-inch deck is the more practical width.
Mistakes to avoid
- Choosing by the trimmer alone. A combo is a mower, a trimmer and an edger, and the deck width matters for any mowing job.
- Ignoring the battery count. The BLACK+DECKER MTC220 includes two batteries, the Gisam YL-30 includes two 4.0Ah batteries, and the SmartGiant listing describes a single battery in its specs, so the runtime you get depends on what is in the box.
- Using the circular saw blade with the base attached. The Gisam listing says the base must be fully removed before using the saw blade.
- Skipping the guard and goggles. Each listing includes a guard, and the SmartGiant set also lists goggles and gloves.
- Expecting a full-size mower result. The 12-inch and 6-inch widths are small compared with a walk-behind mower deck.
Who each option suits
A homeowner with a corded outlet near a small or medium lawn should look at the BESTA512CM first, because its listing gives a motor spec and the kit includes the deck. A cordless buyer who wants the most complete kit should choose the MTC220, which includes two batteries, a charger and the deck. A buyer who wants more trimmer blade options and a larger battery set should look at the YL-30. A reader who wants the lightest tool, or who has limited strength or reach, should consider the SmartGiant 4-in-1 unit.
FAQ
What is a lawn mower with weed eater attachment?
It is a single power head with a detachable mower deck and a string trimmer head. Several listings in this group describe a swap between mowing, trimming and edging. The listings do not describe a separate weed eater attachment that fits a gas mower, so check the listing before assuming compatibility with another machine.
Can a combo unit replace a full-size mower?
For a small or medium lawn, a combo can cover the mowing, but the decks in this group are 12 inches wide. The listings describe them as suited to small yards, slopes and tight areas. A larger lawn will take more passes than a full-size deck.
Is a corded or cordless combo better?
Corded units give steady power without a battery to charge, and the BESTA512CM lists a 6.5 amp motor. Cordless units remove the cord, and the MTC220 and YL-30 include two batteries each in their listings. Pick corded if an outlet is close, and cordless if the yard is large or the cord would get in the way.
What warranty do these combo units list?
The BLACK+DECKER BESTA512CM and MTC220 both list a 2 year limited warranty. The SmartGiant listing states a 12-month warranty in its bullets. The Gisam YL-30 listing does not state a warranty term.
Can I use the trimmer head for edging?
Yes, the listings describe edging as one of the uses. The BESTA512CM rotates its trimmer head to convert to a wheeled edger, and the MTC220 lists a trimmer and edger in its kit. The SmartGiant unit lists a 0 to 90 degree head for edging along driveways and walks.
How should I store a combo unit?
The listings do not give a full storage routine. Keep the battery and charger in a dry place, and follow the manual for your specific unit. For general winter care of a mower and battery, read the linked guides below.
Bottom line
Choose the corded BLACK+DECKER BESTA512CM for a yard near an outlet, and the cordless BLACK+DECKER MTC220 for a complete battery kit with a deck and two batteries. The Gisam YL-30 suits owners who want multiple trimmer blade types on a 12-inch deck. The SmartGiant 4-in-1 unit is the lightest option when reach and weight matter most. Check the cutting width, the battery count and the warranty term in each listing before you decide.
