Yardworks Grass Trimmer

You know the feeling. You pulled the cord on your gas trimmer six times, it coughed once, and now your arm hurts. Or you wrestled with an extension cord across the whole driveway, then spent ten minutes untangling it from the rose bushes. A cordless trimmer solves both problems, but picking the right one takes a bit of homework.

A great cordless grass trimmer needs real cutting power, a line feed system that doesn’t make you stop every 30 seconds, and enough battery life to finish the job. Add in comfort features like adjustable handles and pivoting heads for edging, and you have a tool you’ll actually reach for. Skip those things and you’ll hate every minute of trimming.

We compared five cordless trimmers that compete directly with the Yardworks grass trimmer lineup you see at Menards. They range from a lightweight 10-inch model for small townhouse yards to a full trimmer-and-blower combo for bigger properties. One picks the best overall, but all five earn their spot depending on your lawn size and budget.

Here’s a quick look at the specs that separate these five trimmers.

KOMASTY 20V Cordless Trimmer

The KOMASTY 20V cordless string trimmer is a folding, space-saving tool built for small yards and townhouse patios. It’s the pick for anyone who keeps their trimmer in a closet or apartment storage room, because the shaft folds in three ways for vertical storage.

What stands out here is the 9,500 RPM motor. That’s the highest RPM in this entire lineup, and it makes a noticeable difference when you’re cutting through thick meadow grass or overgrown weeds near the fence line. The 12-inch cutting swath clears ground fast, and the auto-feed line system means you won’t bump the head on the ground to advance the string. The head pivots 90 degrees and the handle rotates 180 degrees, so reaching under benches or along sloping flower beds isn’t a workout. You also get two 2.0Ah batteries, which together deliver about 30 minutes of run time.

The trade-offs are real, though. Thirty minutes of total run time is enough for a small yard, but if you’re pushing through heavy grass, you’ll likely use both batteries in one session. KOMASTY also warns against cutting excessively thick or dense grass, and you need to keep the head parallel to the ground so the line doesn’t snap. The batteries should cool down a few minutes before recharging, which slows down the turnaround.

• 9,500 RPM motor with 12-inch cutting swath
• 180-degree folding shaft for compact vertical storage
• 90-degree adjustable head and 180-degree rotatable handle
• Auto-feed line system requires no bumping
• Comes with two 2.0Ah batteries and a charger

Best for: Apartment dwellers and small-yard owners who need a trimmer that disappears into a closet when the job is done.

CRAFTSMAN 20V MAX Weedwacker

The CRAFTSMAN 20V MAX WEEDWACKER combo kit bundles a string trimmer and a leaf blower in one box, so it’s the choice for anyone who wants to finish lawn day with two tools instead of one. This is a practical kit for suburban yards where the driveway, walkway, and patio all need a final cleanup pass.

The trimmer side gives you a 13-inch cutting swath, the widest of any pick here, and it edges well thanks to a telescoping pole that extends to match your height. The auto line advance feeds 0.065-inch line without bumping, and the blower kicks out up to 340 CFM at 90 MPH through a dual-speed motor. That blower power easily pushes grass clippings off a driveway and moves light leaves across a patio. Having both tools share the same battery platform means you buy one charger, one spare battery, and you’re covered for the whole yard.

The catch is the brushed motor on the trimmer. Brushed motors are older technology; they work fine for routine trimming but they don’t deliver the outright torque of a brushless design, and they can wear faster over years of heavy use. This kit is also listed as having scarce stock, so if you see it available, it may not stay in stock long.

• Trimmer plus leaf blower in one kit with battery and charger
• 13-inch cutting swath, the widest in this roundup
• Telescoping pole makes edging and trimming more comfortable
• Blower reaches 340 CFM and 90 MPH with dual-speed control
• Auto line advance feeds 0.065-inch line

Best for: Homeowners who want one battery platform to run both their trimmer and their blower.

BLACK+DECKER 20V MAX Trimmer

The BLACK+DECKER LST300 is a 2-in-1 trimmer and edger with a 12-inch steel deck, and it’s the most proven, no-fuss design in this group. This is the trimmer for someone who wants to flip a switch, convert from trimming to edging, and finish without fiddling with parts.

Its POWERDRIVE transmission delivers 6,200 RPM from the motor straight to the cutting string, which sounds modest next to the KOMASTY’s 9,500 RPM, but in practice it handles regular weekly grass without bogging down. The automatic feed spool advances line when needed, so you won’t bump the head. BLACK+DECKER built this with reduced vibration, and it shows: the handle stays comfortable even after 20 minutes of trimming along a curb. It is noticeably quieter than a gas trimmer, and there’s no fuel mixing, no priming, and no pull cord to yank.

The honest limitation is that the 6,200 RPM motor isn’t built for chest-high weeds. If you’ve neglected the yard for a month, this trimmer will struggle in the thickest patches. The line feed system is generally reliable, but some users find the auto spool can occasionally overfeed, which wastes line. It also uses a single standard battery, so runtime depends on your trimming pace more than on total capacity.

• 12-inch cutting swath with steel deck for durability
• 6,200 RPM POWERDRIVE transmission
• 2-in-1 converts from trimmer to edger in seconds
• Reduced vibration design with adjustable handle and height
• Quieter operation than gas trimmers

Best for: Homeowners who want a reliable, low-maintenance trimmer that does double duty along driveways and garden edges.

WORX 20V 2-in-1 Trimmer

The WORX WG154 is the lightest trimmer in this roundup at just 4.2 pounds, and it’s the one we’d hand to anyone who dreads heavy yard tools. This 2-in-1 trimmer and edger is made for small to medium yards where maneuverability matters more than raw cutting muscle.

The head rotates 180 degrees, so switching between trimming and in-line edging takes seconds and doesn’t require any tools. The auto feed line system advances the string without bumping, and that’s a relief when you’re working along a sidewalk and don’t want to whack the pavement. The flower guard is the standout feature here: an adjustable spacer stays between the line and your plants, so you can trim right next to petunias without shredding them. That alone makes this worth a look for people with flower beds and landscape ornaments.

The main trade-off is the 10-inch cutting width. It’s narrower than every other pick here, which means more passes to clear the same yard. The single battery is also the standard 20V pack, so if your yard is on the larger side of “medium,” you may want a second battery before you start.

• Weighs just 4.2 pounds
• 10-inch cutting swath, narrower but nimble
• Head rotates 180 degrees for trimming or edging
• Flower guard protects plants while trimming
• Auto feed line with adjustable cutting width

Best for: Gardeners with flower beds who need a light trimmer that won’t destroy their plants.

WORX 20V Trimmer + Blower

The WORX WG928 bundle is the complete yard cleanup package: a 12-inch cordless trimmer, a 360 CFM leaf blower, two batteries, and a quick charger. This is the pick for homeowners who want to handle trimming, edging, and blowing with one tool investment.

The trimmer converts to an edger with a pivot of the head, which matches the WG154’s flexibility, and it steps up to a 12-inch cutting width so you cover more ground in fewer passes. The push-button command feed system is actually the most controllable line feed in this roundup: when you need fresh string, you press a button. That means no guesswork and no waiting for an auto-feed mechanism to catch up. The blower uses turbine tech modeled after a jet engine design, and it moves 360 CFM at 75 MPH. You won’t blow heavy wet leaves across a football field, but for a typical driveway, patio, and lawn edges, it’s plenty.

The trade-off is weight and value math. The trimmer is 5.3 pounds and the blower is 4.4 pounds with batteries attached, so the whole kit feels heavier than the other picks. It’s still balanced, but the KOMASTY and the WORX WG154 are lighter. The blower’s 75 MPH speed is lower than the CRAFTSMAN’s 90 MPH; you’re trading raw air speed for a wider, steadier stream.

• 12-inch trimmer plus 360 CFM turbine blower
• Push-button line feed for on-demand string
• Trimmer converts to edger with a head pivot
• Includes two batteries and a quick charger
• Trimmer weighs 5.3 pounds, blower 4.4 pounds

Best for: Homeowners who want trimmer and blower power from one brand with one battery system.

How We Chose These Products

We started with the Yardworks grass trimmer question that so many buyers search for, then looked at what actually matters for outdoor power equipment: motor RPM, cutting width, line feed reliability, weight, battery capacity, and whether the tool does more than just trim. These five models represent the most common buying patterns we see, from apartment-friendly foldable designs to trimmer-and-blower combos.

Every product here had to meet three criteria. It needed enough power to handle routine lawn maintenance without the hassle of gas. It needed a line feed system that won’t force you to stop constantly and fiddle with the spool. And it needed to be available on Amazon right now, with real-world usability that matches its spec sheet. We left out anything with obvious first-gen flaws or a reputation for snapping string every few minutes.

Buying Guide: What Really Matters

Match the trimmer to your yard size. A narrow 10-inch head covers less ground, but it also stays out of tight spaces and among flower beds, which is why the WORX WG154 works great for small gardens. Wide 12- and 13-inch swaths clear bigger areas faster, but they are bulkier against fences and between shrubs. Consider your dominant task: if you own a suburban yard with lots of concrete edges and pathways, a 2-in-1 trimmer that flips to an edger saves you from buying a separate tool.

Line replacement and maintenance are easy to get right if you buy the correct diameter line. Lighter trimmers like the WORX and BLACK+DECKER use 0.065-inch line, which works well for normal grass and snaps less when you hit a fence. If your yard grows thick weeds, step up to a heavier line and watch the RPM rating, since higher RPM motors like the KOMASTY’s 9,500 turn on a wider range of line thicknesses. Never let the line run down below two inches before you advance it, since short line cuts poorly and puts strain on the motor. And when you wind a fresh spool, keep the line tight and even; loose winding causes tangle jams no matter which auto feed system you use.

Battery care extends trimmer life more than any other habit. Most of these trimmers include a 20V lithium-ion pack, and the ones that ship with two batteries let you keep working while one charges. Heat kills lithium batteries, so let a hot pack cool down before you plug it in. Clean the air vents on the motor housing every few weeks with a dry brush, and check the screws holding the guard and handle after the first few uses. A quick monthly check beats spending an afternoon replacing a cracked guard mid-season.
