You need a mower and a trimmer that work together so your lawn looks finished, not just cut. But finding a pair with matching batteries, enough power, and runtime that lasts the whole yard is where most people get stuck. You end up with a mower that bogs down in thick grass or a trimmer that dies before you finish the edges. This guide matches each combo to the yard size and terrain it handles best.
I’m Rikta, the writer behind Lawn Gear Lab. This guide compares published specs and real customer review patterns, so you get honest strengths and trade-offs—not marketing claims.
You will find six mower-and-trimmer sets, from a compact 9.9-lb 3-in-1 for a small patch to a 22-inch gas self-propelled deck for a large slope. Each fits a specific yard size and terrain. Whether your lawn is a tight 25×10 ft plot or a half-acre, there is a mower trimmer combo here that finishes the job without a dead battery.

How To Choose The Best Mower Trimmer Combo
A good combo balances three things: your lawn size, grass thickness, and how much maintenance you want. Here is what the specs actually mean for your yard.
Match the cutting width to your lawn size
A 12-inch mower (like the BLACK+DECKER or ZEGJAW) fits a small patch under 2,000 sq ft and stores in a closet. A 20-inch or 22-inch deck (like the Greenworks 40V or SENIX) cuts a 5,000+ sq ft lawn in far fewer passes. Each extra inch of width saves you time on every row.
Check the battery amp-hours (Ah) for real runtime
Battery voltage (20V vs 40V vs 48V) determines power. The amp-hour (Ah) rating determines how long it lasts. A 2.0Ah pack gives roughly 15-20 minutes of mowing. A 4.0Ah or 5.0Ah pack can stretch to 30-45 minutes. Combo kits with two batteries let you run one while the other charges, but check if both batteries are the same capacity—a mismatched set (5Ah + 2Ah) means one dies much faster.
Gas vs battery: which suits your setup
Battery-powered combos are quieter, lighter, and start with a button—no gas, no oil, no pull cord. They suit most small to medium yards. Gas-powered sets (like the SENIX 170cc) deliver maximum torque for tall wet grass and slopes but add weight (72.8 lbs for the mower alone) and need fuel mixing or storage. A battery kit around 40V-48V handles a standard 1/4-acre lawn. A gas setup handles a half-acre or more without worrying about runtime.

In‑Depth Reviews
1. Greenworks 40V 20″ Cordless Lawn Mower + Axial Blower + 12″ String Trimmer Combo
You get a full-size 20-inch cut, a 3-in-1 mower deck, and a blower that moves 500 CFM (cubic feet per minute)—enough to clear a driveway in seconds.
This kit works when your lawn needs a real mower. The 20-inch steel deck cuts a wide path, and the 7-position height adjustment (35mm to 95mm) lets you drop low for Bermuda grass or raise it for tall fescue. The included axial blower pushes 500 cubic feet of air per minute at up to 120 MPH, so you clear the driveway after mowing fast. Buyers report it “mows 45 min twice/week using both batteries fully.” The setup uses a 5Ah battery for the main run and a 2Ah spare for touch-ups and the trimmer. At 71.3 lbs, it feels solid on uneven ground but is a push mower for flat terrain.
The 12-inch string trimmer shares the same 40V battery platform—Greenworks says it works with over 75 of their tools. The mower offers three disposal options: rear bag, side discharge, or mulch. You can drop clippings as fertilizer without buying extra parts. Unlike the 20V entry-level combos, this kit does not make you swap tiny batteries every 15 minutes. The 5Ah pack gives enough runtime to finish a typical 1/4-acre lot in one go. The catch is weight: the steel deck adds heft. If you have a hilly yard or lift it into a truck bed often, the lighter 48V Greenworks below may handle better.
The strength of the setup
- 20-inch cutting width gives you a wider pass than the 12-inch BLACK+DECKER, so you make fewer rows
- 7-position height adjustment gives you fine control across grass types and seasons
- 500 CFM blower (120 MPH) saves a separate leaf-clearing tool
Where it asks a trade-off
- At 71.3 lbs versus the 9.9-lb BLACK+DECKER, this is no one-hand carry job
- Battery drains faster in thick or wet grass; buyers advise a spare larger battery for longer sessions
Your best bet if: your lawn is 1/4 acre or larger and you want a single battery platform that also runs a powerful blower—no gas, no pull cord.
Look elsewhere for: the lightest possible setup; at 71.3 lbs and with a steel deck, this is not a carry-upstairs machine.
2. Greenworks 48V (24V x 2) 20″ Brushless Cordless Lawn Mower + 12″ String Trimmer + 320 CFM Blower Combo
A 48-volt system with two 4.0Ah batteries and a brushless motor gives you extended runtime without any gas.
Unlike the 40V Greenworks above with a single 5Ah battery, this kit uses a 48V (24V x 2) system with two matching 4.0Ah packs and a dual-port fast charger—both batteries recharge at the same time. The brushless mower motor wastes less energy as heat than a brushed design, so you get more cutting time per charge. The 20-inch steel deck offers the same 3-in-1 flexibility (mulch, bag, side discharge) and 7-position height adjustment as the 40V version. Owners mention the push-button start is ideal for a “husband with sciatica” and that “1/3 acre yard done in 2 steps,” which matches the 4-hour average battery life claim for the set.
The trimmer has an automatic feed spool (AFS) so you never bump the head to release line mid-edge. The blower hits 320 CFM at 90 MPH, which is less power than the 500 CFM blower in the 40V kit but enough for patios and sidewalks. A few customers note a blinking red light on the charger that needs an unplug-and-replug reset. At 71 lbs, this is nearly identical in weight to the 40V Greenworks. The dual-battery system spreads the load and gives a runtime safety net: if one battery dies, the other finishes the job.
The advantage of the 48V system
- Two identical 4.0Ah batteries give balanced runtime—no mismatched packs where one dies early
- Brushless motor extends battery life and tool durability versus brushed alternatives
- 3-year limited warranty covers all three tools
The trade-off
- Blower output (320 CFM at 90 MPH) is lower than the 40V kit’s 500 CFM blower—slower on heavy leaf piles
- Some buyers had charger glitches needing a manual restart
Reach for this if: you want a modern battery platform with matched packs and fast dual charging—best for a 1/3-acre lawn you finish in one session.
Better to pass if: your priority is the most blower power; the 40V Greenworks kit blows harder for the same money.
3. SENIX 22″ Self-Propelled Gas Lawn Mower (170cc) + 17-Inch Gas Weed Wacker + 26.5cc Gas Leaf Blower Yard Tool Kit
The only gas-powered set here brings a 22-inch self-propelled deck and a 17-inch weed wacker that handles thick brush without stalling.
When your lawn is wet, thick, or overgrown, battery power can run out before the job does. This SENIX kit solves that with a 170cc 4-cycle engine on the mower and two separate 26.5cc two-stroke tools for trimming and blowing. The 22-inch stamped steel deck is the widest in this roundup. The self-propelled drive means you only steer—the mower pulls itself forward, even on a slope. The brand says the patented deck design creates a vacuum that lifts wet grass before cutting it, so you do not have to unclog every few feet. Reviewers point out it “handles wet, tall grass (6-8 inches) well with slower pace” and starts “first pull” after a 10-minute assembly.
The string trimmer has a 17-inch cutting width with dual 0.095-inch bump-feed lines—thicker than the 0.080-inch line common on battery trimmers—so it slices through tough weeds without snapping. The leaf blower hits 7000 RPM and pushes 410 CFM at 125 MPH, clearing a driveway faster than any battery blower here. The catch is maintenance: you mix two-stroke oil for the trimmer and blower (the mower takes straight gas from a separate tank), store fuel, and winterize the carburetor at season’s end. Buyers mention a 2-hour assembly for a novice and say the instructions could be clearer about gas and oil ports. At 72.8 lbs for the mower alone, it is the heaviest set here—but self-propulsion helps on flat ground.
What gas gives you
- 22-inch self-propelled mower with 6 cutting heights (1.25″ to 4″)—widest range and widest deck in this guide
- No battery anxiety—refuel and keep cutting as long as you have gas
- 17-inch trimmer with thick 0.095-inch line handles overgrown areas that stall 20V trimmers
The gas trade-offs
- Maximum weight and maintenance—fuel mixing, oil changes, carburetor care
- Noise level higher than any battery set here
Choose this when: your yard is over 1/2 acre, has slopes or dense wet grass, and you are comfortable with basic engine maintenance.
Avoid it if: you want push-button quiet operation and zero fuel storage—stick with a battery kit.
4. STEELITE 40V (2x20V) 17-inch Electric Lawn Mower + 12-Inch String Trimmer + 500 CFM Leaf Blower Combo
A 17-inch mower runs on two 20V batteries, and the blower has a boost button—all for a price that undercuts most single-tool setups.
This kit packs three tools—a 17-inch mower, a 12-inch trimmer, and a 500 CFM leaf blower—with three 4.0Ah batteries and two chargers. The mower uses two 20V packs together to create a 40V system, with a brushless motor spinning at 3400 RPM. The 6-position height adjustment goes from a 0.98-inch scalp to a 2.95-inch tall cut with a single lever. The 40L collection bag (about 10.5 gallons) holds enough clippings for a small yard. The included mulch plug lets you return nutrients to the soil. Buyers call it “well-built” and “quiet” and say the blower “replaces sweeping” thanks to its boost button.
The trimmer converts to an edger with an auxiliary wheel for sidewalk borders, so you do not need a separate tool. The blower matches the Greenworks 40V kit at 500 CFM and 120 MPH, which is high for a value-priced combo. The trade-off shows in the battery system: the mower needs two batteries to run, so you have three batteries total but only one spare set for all three tools. Some buyers reported a defective battery that failed after 5 seconds of use, though the company eventually replaced it. At 30 lbs, this is the lightest mower in the mid-range section—easy to carry upstairs or load into an SUV.
The value equation
- Three tools with three 4.0Ah batteries and two chargers—enough runtime for a small yard (up to 25 min per charge on the mower)
- 500 CFM blower with boost button rivals much pricier separate blowers
- 30-lb mower is easy to lift, store, and maneuver on uneven ground
Where corners show
- The mower needs both batteries to run—if one dies, the whole mower stops until both charge
- A small number of units arrived with defective batteries; the replacement process was not smooth for everyone
Grab this if: your budget is tight but you still want a blower that clears leaves as fast as a premium kit—best value for the bundle count.
Think twice if: you need uninterrupted runtime across a medium lawn; the two-battery requirement means you cannot swap one pack independently.
5. ZEGJAW 20v 13-inch Lawn Mower and 12-inch String Trimmer Combo with 2x 4.0Ah Batteries and Charger
A 20-volt starting point with a 13-inch mower and a trimmer that converts to a wheeled edger—built for first-time lawn owners.
If you are starting from scratch with a small rental yard or grass under 2,000 sq ft, this ZEGJAW combo gives you a mower with 5-position height adjustment (0.98 to 2.95 inches) and a trimmer that switches from string trimming to wheeled edging without tools. The single-lever height changer drops or raises the deck in seconds. The trimmer has a 90-degree adjustable cutting head and a 180-degree adjustable handle, so you can reach under shrubs or along a fence line. Shoppers say it is “lightweight, portable, easy to switch between trimming/edging” and “ideal for elderly users.”
The 8 extra spools are a nice touch—replacement line is already included. The two 4.0Ah batteries claim 30 to 40 minutes each, though buyers report them at “~20 min” each and note the automatic line feed “never works” in some units. At 33 lbs versus the 9.9-lb BLACK+DECKER, it is still manageable for a flat yard. The main frustration from owners is the auto-feed system: some trimmers feed line perfectly every time, and others need manual intervention every few feet. At this price, you trade consistency for affordability. If the automatic feed works on your unit, the combo delivers reliable lawn care for small jobs.
The beginner advantage
- Two 4.0Ah batteries give solid runtime for a 20V system compared with a typical 2.0Ah starter pack
- Trimmer head adjusts 90° and handle adjusts 180° for tight corners and fence lines
- 8 extra spools of line mean you do not need to buy replacements immediately
The inconsistency
- Automatic line feed is hit-or-miss—some units work perfectly, others need frequent manual feeding
- Battery runtime falls short of the 30-40 minute claim in real use (~20 min)
Choose it for: a budget-friendly entry into a 2-tool set that covers mowing and edging without a separate edger purchase.
Better alternatives if: you are confident your yard exceeds 2,000 sq ft—this 13-inch deck will take too many passes.
6. BLACK+DECKER Weed Eater, Lawn Edger and Cordless Lawn Mower 3 in 1 Combo (MTC220)
At 9.9 lbs, this 3-in-1 converts between mower, trimmer, and edger—smaller than most vacuum cleaners.
This is the lightest mower-trimmer combo you will find anywhere. The detachable wheeled deck clips onto the trimmer body to turn the string trimmer into a tiny push mower. A second lever converts it from trimming to edging. The 12-inch cutting width is narrow, but for a 25×10 ft patch of lawn or an apartment courtyard, the trade-off works—you carry the whole thing in one hand. The AFS (automatic feed spool, meaning the line advances without your bumping the head) keeps the line feeding. Buyers confirm it “mowed entire yard on two batteries (~30 min each)” and call it “great ‘baby mower’ for apartment life.”
The PowerDrive system is designed to reduce bogging in dense grass. The telescoping handle adjusts for different heights. But the mower deck is plastic, not steel—durable enough for regular grass but not for rocks or brush. Owners mention it “struggles with grass flattened by wheels; requires vacuum-like pushing” and that the trolley function “takes longer than a mower.” The two included LBXR2020 20V MAX batteries deliver about 15-20 minutes each depending on grass thickness, enough for a small lawn but not for a standard suburban lot. The auto-feed system may jam occasionally, and converting between modes takes a few seconds of lever-pulling.
The tiny-yard solution
- At 9.9 lbs versus the 71.3-lb Greenworks 40V combo, this is the lightest option here, so storage and transport are easy
- Three tools in one (mower, trimmer, edger) without buying separate attachments
- Second battery means you can mow and then trim without waiting for a recharge
The reality check
- Not a replacement for a standard mower on a yard larger than 1,500 sq ft—slow going on wet or tall grass
- The edger function is basically the trimmer held at an edge angle, not a dedicated bladed edger
Perfect for: anyone in an apartment, condo, or townhouse with a tiny lawn who needs one tool that does everything and stores in a closet.
Not for: a half-acre or uneven terrain—the plastic deck and narrow 12-inch cut make large lawns a chore.
Understanding the Specs
Cutting Width
This number determines how fast you finish mowing. A 12-inch deck needs more passes than a 20-inch deck to cover the same area. For a small patch under 1,500 sq ft, a 12- or 13-inch mower is fine. For anything larger than a 2,500 sq ft lawn, a 17-inch or larger deck saves you time and walking.
Battery Voltage & Amp-hours (Ah)
Voltage (20V, 40V, 48V) determines the power the motor delivers—higher voltage cuts thick grass better. The amp-hour (Ah) rating determines how long the battery lasts. A 2.0Ah battery gives roughly 15-20 minutes of mowing. A 4.0Ah or 5.0Ah pack can last 30-45 minutes. Two matching batteries let you swap and keep working while one charges.
Number of Height Positions
More positions (5, 6, or 7) give you finer control over how short or long you cut the grass. A 5-position system lets you choose between, say, 0.98 inches (a short, manicured look) and 2.95 inches (taller, better for summer heat). A 7-position system offers more intermediate steps between those extremes.
Weight & Portability
A 10-lb combo like the BLACK+DECKER is easy to carry up stairs. A 71-lb steel-deck mower is not something you lift often—it stays on the ground. Self-propelled models (like the SENIX gas mower) reduce the effort of pushing, even at 72.8 lbs, by driving the wheels forward automatically.

Final Thoughts: The Verdict
For most buyers, the best mower trimmer combo is the Greenworks 40V 20″ because its wide 20-inch steel deck, 7-position height adjustment, and powerful 500 CFM blower cover a 1/4-acre yard in one battery cycle with zero maintenance. If you want a gas option that handles thick wet grass and slopes without battery anxiety, grab the SENIX 22″ Gas set. And for a tiny courtyard or apartment balcony, the lightweight BLACK+DECKER 3-in-1 at 9.9 lbs is the most compact solution you will find.
