You steer, the mower does the pushing: a self-propelled drive system pulls the machine forward, so your arms and back stay relaxed. The real choice is gas versus battery, and how big your yard is. For most homes, a 21-inch or 22-inch deck cuts the grass in fewer passes, and a single-lever height adjustment from about 1.25 to 4 inches handles both spring scalping and summer growth without tools.

I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.

Whether you are replacing a tired gas mower or leaving pull-cords behind, this breakdown of the best self-propelled push mower options focuses on engine torque, battery runtime, and drive systems that actually perform on real grass.

How To Choose The Best Self-Propelled Push Mower

A self-propelled mower is a big purchase, so getting the drive type and power source right matters more than the color of the deck. Start with your lawn’s shape: a flat, open rectangle needs far less from a drive system than a sloped, irregular yard with flower beds to navigate.

Gas vs. Battery: What Fits Your Routine

Gas mowers win on raw, endless power and are ideal if you have a large yard or let the grass get tall between cuts. Battery mowers trade that for instant starts, no fuel storage, quieter operation, and zero emissions, but you are tied to runtime limits measured in minutes. Think about whether you would rather pull a cord or charge a pack.

Front-Wheel vs. Rear-Wheel Drive

Rear-wheel drive pulls the mower from the back, which gives you better traction on hills and uneven ground because the weight of the engine sits over those wheels. Front-wheel drive is lighter and turns more easily on flat ground, but it can lose grip going uphill. If your yard has any slope, rear-wheel drive is the safer bet.

Cutting Height and Deck Size

You will finish faster with a wider deck, but a 21-inch or 22-inch cut is the practical balance for most homes. Cutting height range matters just as much: a single-lever adjustment from about 1.25 inches up to 4 inches lets you handle both a scalped spring lawn and a taller summer cut without tools.

In‑Depth Reviews

★ Best Overall

1. EGO LM2135SP Plus Extra Battery

Our pick — over 4.5★ from 650+ verified ratings; the strongest balance of quality and price.

56V BatteryTouch Drive

The 56V battery bundle delivers 7.0 ft-lbs of torque, exceeding gas mowers in cutting power.

What wins people over here is outright performance: EGO’s brushless motor puts out 7.0 ft-lbs of cutting torque, which is why owners describe it as exceeding gas mowers rather than merely matching them. The package includes the mower with a 56V 7.5Ah battery, a rapid charger, and an extra 5.0Ah battery that ships separately — so you have a spare ready when the first pack depletes.

Runtime lands at up to 60 minutes on the main battery, and the Touch Drive system lets you engage self-propulsion with a palm press, then scroll a dial at your fingertips to change speed. The Select Cut system ships with three interchangeable lower blades — mulching, high-lift bagging, and extended runtime — plus an upper blade, so you can swap for the job. Cutting height spans from 1 inch up to 4 inches across 8 positions, which is a wider and finer adjustment than rivals offer.

The honest catch is battery math on bigger properties: owners on a half-acre report needing both batteries, and wet or tall grass drains the pack faster. One owner noted the self-propelled drive slows as the battery depletes, so the extra 5.0Ah battery is not a luxury — it is the difference between finishing and stopping. The mower carries a 4.7-star average across 600+ ratings, making it the crowd favorite for good reason.

Why It Leads

  • 7.0 ft-lbs of torque genuinely rivals gas cutting power
  • Spare 5.0Ah battery means you can finish larger yards
  • 8 cutting heights from 1 to 4 inches for fine control

What to Know

  • Half-acre owners will drain both batteries on one mow
  • Self-propel can slow noticeably as the pack depletes

Grab it if: you want gas-level cutting power without the fuel, and your yard is large enough to justify a second battery.

Think twice if: your lawn is small — the extra battery bundle is more capability than a postage-stamp yard needs.

Budget Champion

2. AMERISUN 21″ Self-Propelled Gas Mower

170cc Gas3-in-1

The 170cc gas engine offers reliable self-propulsion at the lowest price in this lineup.

The defining trait of this AMERISUN is its price-to-value read: it is the cheapest self-propelled option in this lineup, yet the 170cc OHV 4-stroke engine with auto choke delivers steady, reliable starts. A 21-inch steel deck carries a 3-in-1 design, so you can mulch, side discharge, or bag into the included 1.4-bushel rear grass catcher, and the foldable handle tucks it away for compact storage.

Cutting height adjusts across 6 positions from 1.5 inches up to 3.9 inches — a smaller range than the top EGO pick, which drops to 1 inch at its lowest. The self-propelled drive reduces effort and adapts to terrain, and buyers report the engine handles thick grass without complaint. The review pages even feature an 84-year-old owner who bought it to stop paying for lawn service, saying “I CANT WAIT to do it again,” which sums up the enthusiasm.

The trade-off is refinement: some owners find the self-propelled speed slow but acceptable, and the rear-wheel drive needs adjustment from the start. It carries a 3.8-star average across almost 500 ratings, so it is a value play rather than a premium finish. If you want gas muscle on a strict budget and do not mind a little setup tinkering, this is the one.

A value verdict: The lowest entry price into self-propelled gas ownership, with a 170cc engine that punches above its cost bracket. The slower self-propel speed and careful initial setup are the compromises you accept for the savings.

Easy Start Pick

3. PowerSmart 21″ Self-Propelled Gas Mower

170cc GasRear-Wheel Drive

The 170cc rear-wheel-drive gas mower starts on the first pull and cuts a consistent 21-inch path.

The PowerSmart earns its spot with a 170cc OHV engine (overhead valve, a design that starts easily and runs steadily) that owners confirm: 71-year-olds are mowing their own yards with it and calling it wonderful. The 21-inch cutting width uses a sturdy steel deck that covers a wide path to trim mowing time on medium to large yards. With a 20.98-inch cut, it is a hair narrower than the 21-inch AMERISUN above — a rounding difference you will never feel.

It runs the same 6-position height range from 1.5 to 3.9 inches as the AMERISUN, adjusted with a single lever. The rear-wheel drive with 10-inch rear wheels provides real traction on slopes and uneven terrain, which is the configuration you want for any yard with a hill. The 3-in-1 function lets you bag into the 1.4-bushel catcher, mulch to feed the lawn, or rear-discharge for speed.

The recurring gripe is the self-propelled drive: some owners mention it failing after a couple of months of light use, leaving the mower hard to push manually — as one put it, “manual push is hard.” Quality control appears inconsistent, with early units arriving with bent deck brackets before Amazon replaced them. At a 3.6-star average, it is the riskiest pick here, so weigh the even cut and easy start against the drive reliability concerns.

The honest read: Excellent cutting performance and easy assembly when the unit is right, but the self-propel drive has a documented failure pattern that makes this a gamble. Best for buyers who accept that risk for the lower price.

Traction Specialist

4. YARDMAX 22″ Select PACE CVT Mower

201cc Gas6-Speed CVT

The 22-inch gas mower’s 6-speed CVT lets you match walking pace to terrain.

YARDMAX stands out with its exclusive CVT (continuously variable transmission), which offers superior speed variability through a 6-speed shift lever, so you match the mower’s pace to your walk instead of fighting it. Exclusive rubber tires with an aggressive spiked tread add traction and maneuverability, making this a strong candidate for hills and uneven ground. The 201cc engine starts easily with an automatic choke — no priming or choking needed.

The 22-inch cutting width is the widest in this lineup, sharing that spec with the bigger SENIX, and it covers ground quickly. A single-lever deck adjustment sets mow height across all four wheels at once, and a deck cleanout port lets you wash the underside without flipping the machine. At 84.9 pounds, this is a heavy unit, and owners note the weight is part of the traction story.

The catch is the front-wheel drive: customers note the speed lever can slip, making the 6 speeds less effective, and wet grass causes traction loss. It carries a 4.1-star average across 340+ ratings, and the praise centers on power, value, and easy starting. If your yard is flat and you want the widest cut with the most speed options, this delivers — just know that FWD is not the hill climber that rear-wheel drive is.

Where It Shines

  • 22-inch deck is the widest cut in this list
  • 6-speed CVT adjusts pace on the fly
  • Spiked rubber tires boost grip

Watch For

  • Front-wheel drive loses traction on wet grass
  • At 84.9 lbs, it is heavy to maneuver around tight corners

Choose this if: you want the widest cut and variable speed control on mostly flat ground.

Look elsewhere if: your yard is sloped — the FWD system is not built for steep climbs.

Lightweight Gas

5. SENIX 21″ Self-Propelled Gas Mower

170cc GasRear-Wheel Drive

At 61.7 pounds, this 170cc gas mower delivers 3.8 HP with a lightweight steel deck.

At 61.7 pounds, this SENIX is the lightest gas mower in the lineup, and owners describe it as “lightweight and a lot of power.” The 170cc 4-stroke engine delivers 3.8 HP and 6.5 ft-lb of torque, with a high-strength steel deck and a 21-inch cutting width. It targets yards around 1/3 acre, which is the balance for this power level.

The drive system uses rear-wheel drive with 8-inch front and 11-inch rear wheels, giving it solid capability on rough terrain and sloped lawns. Cutting height adjusts through 6 positions from 1.25 inches up to 3.75 inches, and a unique vortex tunnel design reduces grass buildup under the deck. The 3-in-1 steel deck supports mulching, side discharge, and rear bagging with the included 16-gallon bag.

The trade-offs are small but real: owners note the handles feel thin and flimsy, and one reviewer noted a blower attachment breaking off after the second use, leaving only mulch mode. It carries a 4.2-star average from a smaller review pool of about 40 ratings, with a couple of owners reporting units that stopped working early. For a light, quiet gas mower that is ready to go with included oil, this is a solid mid-range pick.

The takeaway: A genuinely light gas mower with strong torque for its size, held back by thin handle construction and occasional early failures. The 2-year warranty backs it, but treat the plastic attachments gently.

Compact Battery Pick

6. SKIL PWR CORE 40 Self-Propelled Mower

40V BatteryPush-Button Start

The 40V battery mower’s 20-inch deck and 50-minute runtime make small-yard mowing quick and quiet.

The SKIL’s digital brushless motor provides efficient, high-performance power without the hassle of gas, and reviewers point out mowing a lawn in about 10 minutes versus over an hour with a gas mower. Runtime reaches up to 50 minutes on a single charge with the included 40V 6.0Ah battery, and shoppers say the pack often lasts for multiple mows on smaller properties. The push-button start and variable-speed self-propel make it easy to begin and easy to match your pace.

A single-lever deck adjustment offers 7 settings from 1.5 to 4 inches — a wider range than the gas SENIX above, which tops out at 3.75 inches. The 3-in-1 functionality lets you bag, mulch, or rear-discharge, and the telescoping handle folds for vertical storage in tight spaces. The 20-inch cutting width is the narrowest here, but it suits confined areas and small yards where maneuverability beats raw coverage.

The battery life here is the thing everyone raves about, with a 4.4-star average and strong owner sentiment on runtime and effectiveness. Some owners note the self-propel drive is louder than the motor itself, and wet or thick grass can strain it. There was a battery recall in December 2024 for earlier units, so check your serial number — but the current kit is a proven, lightweight cordless option.

Why Owners Love It

  • Up to 50 minutes of runtime on the 6.0Ah pack
  • Light enough to push manually without self-propel
  • 7 height positions from 1.5 to 4 inches

The Small Print

  • 20-inch deck is the narrowest cut in this list
  • Self-propel motor is noticeably louder than the cutting motor

Best for: small to medium flat yards where light weight, quiet operation, and easy storage rank above cutting width.

Skip if: you have a large or steep lawn that needs the wider deck and higher voltage of the bigger battery mowers.

Thick Grass Handler

7. SENIX 22″ 201cc Variable Speed Mower

201cc Gas22-inch Deck

The 201cc gas engine powers through wet, overgrown grass with a 22-inch rear-wheel-drive deck.

This SENIX pairs a powerful 201cc four-stroke OHV engine with a 22-inch cutting width — one of the widest in the lineup — to finish large yards faster. Owners specifically praise how it handles tall, thick grass and even wet overgrown lawns with ease, thanks to the rear-wheel drive traction and variable speed control. The engine starts easily, with many buyers reporting first-pull starts after priming.

A single-handle, four-wheel synchronized height adjustment system moves from 1.25 inches to 4 inches across 6 positions, letting you set the perfect height without bending to each wheel. The 3-in-1 steel chassis offers shredding (mulching), side discharge, and rear bagging, and the 64-pound weight is manageable for a gas mower. A 2-year warranty backs the unit for confidence.

The catch is durability and starting consistency: the customer data flags 24 mentions of durability issues, and while starting performance is the top positive at 76 mentions, a separate “starting experience” group of 22 is mixed. Some buyers report bolts loosening and falling out within weeks, and others find it hard to restart mid-mow. It also carries a 4.0-star average, and one owner notes the tallest cut setting still resembles a golf fairway.

The balance: Outstanding cutting power on thick grass with a wide deck, but inconsistent build quality and restart hiccups mean you should check hardware periodically. A strong performer that demands a little maintenance attention.

Top Performer

8. Greenworks 80V 21″ Self-Propelled Mower

80V BatteryLED Headlight

The 80V brushless motor cuts up to half an acre at 3x quieter operation than gas.

The headline spec here is the 80V brushless motor, which provides more torque and longer life while running 3x quieter than gas. Owners confirm the power is “awesome,” with a 4.5-star average and performance being the thing everyone raves about — it is the top positive aspect by a wide margin. The rear-wheel drive with variable speed control gives maximum traction and control, and the 21-inch steel deck handles steep hills.

Runtime is the mixed note: the 80V system cuts up to 1/2 acre with a fully charged 4.0Ah battery, and battery life shows 118 mentions split between positive and mixed — owners on larger properties report needing multiple packs. A 4-in-1 system covers mulching, bagging, side discharge, and turbo leaf pickup, and the LED headlight enables early morning or late evening mowing. At 75 pounds, it is not the lightest, but owners say it is light enough to skip the self-propel on flat ground.

Owners consistently praise the instant start, quiet operation, and easy height adjusters, and batteries hold a charge for 6+ months in cold storage. The caveats are minor: the self-propel can lock the rear wheels if not disengaged early, and mulch quality is only adequate in thick patches. For a premium battery mower with serious power and a proven track record, this is a top contender.

What Wins People Over

  • 80V brushless motor with serious torque, 3x quieter than gas
  • Rear-wheel drive handles steep hills and rough ground
  • 4-in-1 system adds turbo leaf pickup

The Trade-Off

  • Battery life is mixed for large yards — a second pack helps
  • Mulch quality is only adequate in very thick grass

Reach for this if: you want premium electric power with hill-climbing rear-wheel drive and can budget for an extra battery on bigger lawns.

Weigh the cost if: your yard is under a quarter-acre — the 80V capability exceeds what a small flat lawn demands.

Lightweight EGO

9. EGO 21″ Self-Propelled Mower LM2114SP

56V BatteryDual-Toggle Drive

The 50.9-pound EGO that is light enough for anyone in the house to handle.

This EGO is the lightweight entry into the brand’s 56V ecosystem, and the 7-position cutting height from 1.25 to 4 inches is its standout control feature. The Dual-Toggle handleset engages the self-propel system with either hand, which is a thoughtful design for maneuvering around obstacles. It delivers up to 6.0 ft-lbs of cutting torque, which owners say exceeds their old gas mowers.

Runtime is up to 50 minutes on the included 56V 6.0Ah ARC Lithium battery, and owners mention the pack lasting for two mows on smaller yards. The high-efficiency brushless motor provides long runtimes and low vibration, while the 21-inch deck and push-button start make it simple. Bright LED headlights and an adjustable handle height round out a very complete package.

The catch: on a small flat lawn, the battery barely lasted one mow for some owners, blinking red at the end, so a second pack is recommended for normal or larger yards. It also clogs on grass over 6 inches tall, even with the side chute. At 4.4 stars, it is well-loved, and one owner replacing a 40-year-old Honda called it lighter, more maneuverable, and quieter. If you are already in the EGO ecosystem, this is the logical upgrade.

The fit: The lightest EGO mower at 50.9 pounds, perfect for smaller users, but treat it as a small-to-medium yard machine unless you buy a second battery. The dual-toggle drive is a genuinely smart touch for tight spaces.

Two-Battery Power

10. Greenworks 60V 21″ Mower with Two Batteries

60V Battery4-year Warranty

Two 4.0Ah batteries and a 60V motor built to conquer up to 3/4 acre per charge.

The Greenworks 60V system is designed for large yards, delivering gas-like power with up to 3/4 acre per charge across two 4.0Ah batteries. Battery life is the top positive aspect, and customers note one battery cutting a moderately large yard while the second finishes the front. The rear-wheel drive offers strong traction on slopes and thick grass, with on-the-go speed adjustment for precise control.

It runs 3x quieter than gas, starts instantly, and produces zero emissions, with an LED headlight for dawn-to-dusk mowing. The 4-in-1 system adds turbo leaf pickup to the standard mulch, bag, and side discharge modes. A 4-year tool and 4-year battery warranty backs the investment, and the mower works with 75+ Greenworks 60V tools, so you can expand your cordless toolkit.

At 65 pounds, it is not heavy, but owners note the wheels can lock on release and the auto battery swap can glitch — one owner reported the mower running weakly before switching packs about 40% of the time. The 4.4-star average is solid, and the sentiment is that this is cheaper than comparable EGO or Toro models. The suction is weaker than a gas Honda on leaves, so treat it as a grass mower, not a leaf vacuum.

The Ecosystem Win

  • Two 4.0Ah batteries handle up to 3/4 acre
  • 4-year warranty on both tool and batteries
  • Compatible with 75+ Greenworks 60V tools

Watch Out For

  • Auto battery swap can glitch and run weakly before switching
  • Wheels can lock when you release the drive lever

Pick this if: you have a large flat yard and want a full battery ecosystem with a strong warranty.

Consider otherwise if: the auto-swap quirk and wheel-lock behavior annoy you — the simpler single-battery EGO models avoid that complexity.

Maximum Torque

11. EGO LM2156SP with 10.0Ah Batteries

56V Battery8.3 ft-lbs Torque

The 8.3 ft-lbs flagship that cuts 6-8 inch grass without bogging down.

This is the most powerful EGO in the lineup, delivering up to 8.3 ft-lbs of cutting torque — enough that owners say it matches gas mowers and cuts 6-8 inch grass without stalling. The Select Cut system includes interchangeable lower blades for mulching, high-lift bagging, and extended runtime, plus an upper blade. Runtime stretches to up to 75 minutes on the included 56V 10.0Ah battery, the longest in this list, with a 700W turbo charger to refill it fast.

The Touch Drive self-propelled system engages with a palm press and adjusts speed with a fingertip dial, and the 8 cutting height settings range from 1 to 4 inches. Reviewers point out handling a 1/3 to 3/4-acre yard on one charge, with battery lasting most of the lawn. Push-button start, LED headlights, adjustable handle height, and IPX4 weather resistance round out a flagship feature set.

The self-propelled system is the mixed note: some owners find it maneuverable while others report the button and rotary switch are poorly designed, and the drive can pull “like a dog” for smaller users. The 10.0Ah battery still struggled to finish a yard in heavy grass with mulching and self-propel active. At 4.5 stars, it is the torque king here — if you want the absolute strongest cut quality and can handle the hefty price, this is the flagship to beat.

The flagship verdict: class-leading 8.3 ft-lbs of torque and 75-minute runtime make this the most capable battery mower for tough grass. The self-propel control design and occasional wheel lock are the compromises on an otherwise stellar machine.

Understanding the Specs

Cutting Torque (ft-lbs)

This is the rotational force your blade applies to the grass. Higher torque in ft-lbs means the mower can power through thick, tall, or wet grass without bogging down. Gas engines are rated in HP while battery motors use ft-lbs, so compare apples to apples: a brushless motor with 7.0 ft-lbs or more genuinely rivals a 170cc gas engine on cutting power.

Battery Runtime (Minutes)

For cordless mowers, this is the single most important number. A single charge measured in minutes tells you exactly how long you can mow, but real-world runtime drops in wet or tall grass. Match the rated minutes to your yard: a 50-minute pack suits a third of an acre, while a 75-minute pack handles more — and a second battery is always a safe backup.

Cutting Height Positions

The number of height settings and their range in inches determines how precisely you can match your lawn’s needs. More positions, like 8 settings from 1 to 4 inches, give finer control over cut length. A single-lever adjustment that moves all four wheels at once saves you from bending down to each corner of the deck.

Drive System Type

Self-propelled mowers come in front-wheel drive (FWD) or rear-wheel drive (RWD). FWD is lighter and turns easily on flat ground, while RWD pulls from the back where the engine weight sits, giving better traction on slopes. Variable speed control lets you match the mower’s pace to your walk instead of fighting the handle.

FAQ

How much lawn can a battery self-propelled mower handle on one charge?
It depends on battery amp-hours and grass conditions. A 40V 6.0Ah pack gives roughly 50 minutes, enough for a third of an acre on flat ground. The 56V 10.0Ah EGO stretches to 75 minutes and handles up to 5,000 square feet, while a 60V dual-battery kit covers up to 3/4 acre. Wet or tall grass drains any pack faster.
Is rear-wheel drive better than front-wheel drive on hills?
Yes for slopes. Rear-wheel drive pulls from behind, where the engine or battery weight sits, giving the rear wheels more grip on inclines. Front-wheel drive is lighter and turns more easily on flat ground but can lose traction going uphill, especially on wet grass. If your yard has any real slope, choose a rear-wheel-drive model.
How does cutting torque in ft-lbs compare to gas engine HP?
They measure different things: gas engines are rated in horsepower while electric motors use ft-lbs of torque. In practice, a brushless battery motor with 7.0 to 8.3 ft-lbs of torque genuinely matches or exceeds a 170cc gas engine for cutting thick grass. Owners of the 8.3 ft-lb EGO report cutting 6-8 inch grass without the motor bogging down.
What does the cutting height range actually control?
It sets how low the blade sits, which determines how short you cut the grass. A range from 1 to 4 inches across 8 positions gives you fine control: scalp a lawn short in spring, leave it taller in summer heat, or adjust for the season. A single-lever adjustment that moves all wheels at once is much faster than adjusting each wheel individually.
Will a self-propelled mower work on very steep slopes?
Rear-wheel-drive models handle moderate slopes well because the weight sits over the drive wheels. The EGO and Greenworks rear-drive units get consistent praise for hill climbing. For extremely steep terrain, you may still need to push manually or consider a different tool — no walk-behind mower is designed for cliffs.
How long do the batteries last before needing replacement?
The data shows owners using Greenworks batteries that hold a charge for 6+ months in cold storage, and YARDMAX offers a 5-year spare part availability window. Real-world battery lifespan depends on charge cycles and storage conditions. The Greenworks 60V kit includes a 4-year battery warranty, which is the strongest protection in this lineup.
What is the difference between a 40V and 56V battery mower?
Voltage is a measure of electrical pressure — higher voltage generally means more available power for the motor. The 40V SKIL offers 50 minutes of runtime on a 6.0Ah pack, while 56V EGO models deliver more torque (7.0 to 8.3 ft-lbs) and longer runtime up to 75 minutes. Higher voltage systems also tend to be compatible with more tools in the same battery ecosystem.
Can I use the same battery across multiple yard tools?
Yes, if you stay within one brand’s ecosystem. EGO batteries work across all EGO 56V tools, and the Greenworks 60V mower is compatible with 75+ Greenworks 60V tools like trimmers, blowers, and chainsaws. This is a major cost advantage if you already own tools in that voltage family, or plan to expand.
What maintenance does a battery mower need vs a gas one?
Battery mowers need almost none: no oil changes, no spark plugs, no fuel stabilizer, and no winterizing. Shoppers say simply storing the mower upright with the battery removed. Gas mowers need oil, fuel, and seasonal storage care, but they never run out mid-yard if you keep fuel on hand. The EGO and Greenworks owners consistently cite “no gas, no oil” as a top relief.
Is a 21-inch deck meaningfully better than a 20-inch deck?
On a typical suburban lawn, the difference is minor — one extra inch of cutting width saves a few passes per mow. The 22-inch decks on the YARDMAX and bigger SENIX make a more noticeable difference on large yards. Deck width matters most when you are covering a lot of ground, not on a small postage-stamp lawn.

Final Thoughts: The Verdict

For the majority of shoppers, the winner is the EGO LM2135SP because its 7.0 ft-lbs of torque, 60-minute runtime, and spare battery make it the rare cordless mower that truly replaces gas. If you want maximum cutting power for tough, overgrown grass, grab the EGO LM2156SP with its 8.3 ft-lbs of torque and 75-minute runtime. And for the best gas-powered value on a budget, the AMERISUN 21″ delivers a 170cc engine and self-propelled drive at the most accessible price point in this lineup.
