With a sloped yard or brush along the fence line, switching between a mower for the open grass and a trimmer for the tough spots can mean extra trips to the garage. This combo handles both with a 20-inch push mower on 7-inch wheels for stability on uneven ground and a 22-inch walk-behind string trimmer with 14-inch rubber wheels that roll over roots and rocks. After a couple mows, you’ll notice how the adjustable heights—three on the mower from 1.35 to 3.15 inches, five on the trimmer from 1.57 to 3 inches—make tackling varied terrain straightforward without constant tweaking. Just keep in mind it arrives in two packages, sometimes a day apart.

Homeowners with yards over a quarter acre, especially those in suburban or rural spots around the Midwest or South, often reach for this combo when their property mixes open grass with tricky edges. Think sloped backyards, fence lines choked with weeds, or rough patches where a regular mower bogs down or tips. It’s common for folks in their mid-30s to mid-50s, handling their own yard work to skip hiring services that run $100 a pop. They deal with post-winter overgrowth or mid-season failures of weaker tools, switching between mowing flat areas and clearing brush without wanting multiple machines cluttering the garage.
Key Features & Benefits
20-Inch Mower with 144cc 4-Cycle Engine
The mower cuts a 20-inch swath with side discharge and a 144cc engine that runs on straight gas, no oil mixing needed. On open lawns, it powers through thicker grass without stalling, letting you cover ground steadily during weekly mows. The three height settings—1.35, 2.3, and 3.15 inches—match varying grass lengths, so you adjust once per session rather than fighting uneven cuts.
22-Inch Walk-Behind String Trimmer with 160cc Engine
This trimmer uses 0.155-inch line across a 22-inch width, driven by a 160cc 4-cycle engine for tackling dense weeds. It shines along fence lines or overgrown brush where blades can’t reach, with five height adjustments from 1.57 to 3 inches to skim close without scalping soil. Over time, users notice it handles repeated passes on tough spots better than handheld versions that tire you out.
Wheels for Uneven Ground
Front and rear 7-inch wheels on the mower keep it stable on slopes, while the trimmer’s 14-inch rubber wheels roll over rocks and roots. In yards with hills or rugged edges, this setup prevents tipping or getting stuck, making sessions shorter and less frustrating, especially after rain when ground softens.
Two-Piece Combo Setup
One package holds the mower, the other the trimmer, which might arrive a day apart. This covers both lawn and brush needs without separate shopping trips, fitting routines where you mow the main area one day and edge the wild parts the next.
What to Consider When Buying
Gas tools like this mean dealing with fuel storage and pull-starts, so factor in garage space and your comfort with that routine. The push mower works for lots up to half an acre but may feel heavy on long sessions over very hilly ground.
- Check your yard layout—open grass suits the mower, but measure rough areas to confirm the trimmer’s 22-inch cut fits tight spots.
- Expect some assembly; wheels and handles take 30-45 minutes total, easier with basic tools.
- Durability holds on weekly use, but avoid cheap gas stabilizers to prevent engine gumming.
- Common mistakes: Underestimating split shipments, leading to impatience; skipping height tests first mow, causing uneven results; ignoring terrain wheel limits on steep slopes over 15 degrees.
How to Choose the Right One
Start by walking your yard: note flat lawn size versus brushy or sloped sections. If over 70% is mowable grass with some rough edges, this combo matches without excess power. Use this checklist—engine sizes (144cc mower, 160cc trimmer) for your grass density; wheel specs for your terrain type; height ranges covering your typical cuts. Compare to single-tool options only if your yard lacks variety. Test pull-start ease in-store if possible, and confirm shipping patience for two boxes.
Why This Is a Smart Choice
Over a season, it streamlines yard work by handling diverse areas in one set, cutting time lost swapping tools or calling pros. The 4-cycle engines run reliably on repeated use, with wheels proving steady across real slopes and roots—not flawless, but consistent for mixed properties. A minor trade-off is the staggered delivery, yet it avoids buying mismatched pieces later. Users settle into a rhythm where the mower clears bulk grass first, trimmer finishes edges, building efficiency by the third outing.
Care & Maintenance Tips
After each use, clear clippings from under the decks to avoid clogs next time. Run the engines dry if storing over winter.
- Change oil after 5-10 hours; fresh gas with stabilizer lasts 30 days without issues.
- Sharpen trimmer line by swapping spools when frayed—keeps cuts clean longer.
- Store upright in a dry spot; wheels last seasons with occasional cleaning of rubber treads.
- Small insight: Prime the carburetor gently on cool mornings for easier starts after sitting a week.
FAQs
Q: How does this combo handle a yard with both flat grass and overgrown fence lines?
A: The 20-inch mower works well for open lawns with its side discharge and 144cc engine, while the 22-inch string trimmer tackles brushy edges and rough spots using its 160cc engine and 0.155-inch line. On a typical half-acre lot, you switch from mowing the center to clearing fence lines without needing extra tools. The trimmer’s 14-inch rubber wheels help it roll over roots and rocks that would stop a regular mower.
Q: What cutting heights can I set on the mower and trimmer for different grass types?
A: The mower has three positions from 1.35 to 3.15 inches, letting you adjust for short lawn grass or taller patches. The trimmer offers five settings between 1.57 and 3 inches, useful for weeds or uneven ground. In practice, starting at the higher setting prevents bogging down in thick growth, then lowering as you go.
Q: Will these tools manage slopes or bumpy terrain without tipping?
A: Both have larger wheels for stability—the mower’s 7-inch front and rear wheels grip on inclines, and the trimmer’s 14-inch rubber wheels glide over uneven spots like roots or gravel. Users on sloped suburban yards find they navigate better than smaller-wheeled push mowers. Expect a bit more push effort uphill compared to self-propelled models, but it stays steady.
Q: How do I maintain the engines and line after regular use?
A: These 4-cycle engines run on straight gas, no oil mix needed, so check oil levels before each mow and refill as usual. For the trimmer, advance the 0.155-inch line when it wears down, which happens gradually over a few fence-line passes. Wipe down the wheels and deck after sessions in damp grass to avoid buildup, keeping things running smooth through the season.
Q: What’s the assembly like when the two packages arrive?
A: They ship separately and might arrive a day apart, but each comes with straightforward setup for the handlebars, wheels, and basic attachments. The mower takes about 20-30 minutes to put together, similar for the trimmer. One common step is securing the height adjustments firmly to avoid slippage during first use.
Q: How does the string trimmer compare to a basic mower for thick weeds?
A: Unlike a mower blade that stalls in heavy brush, the trimmer’s line and high wheels cut through tall weeds along fences or rough edges without clogging. It covers a 22-inch swath efficiently where the mower’s 20-inch deck can’t reach. Over time, the line thins out, so having spare on hand avoids mid-job stops.
Q: Can I expect even cuts on uneven ground with the height adjustments?
A: The multiple settings on both tools let you match the terrain, like raising for tall grass on bumps or lowering for a clean finish on flats. In real yards with dips and rises, it gives consistent results better than fixed-height options. A quick tweak between areas keeps the deck level without much hassle.
