Best Large Push Mowers for Covering Big Yards
As an Amazon Associate we earn from qualifying purchases.
A large push mower is a walk-behind mower with a wide cutting deck, usually 18 inches or more, that is built to finish a big lawn in fewer passes than a compact model. The best large push mower for your yard depends on how much grass you have, whether you want a cordless or gas engine, and whether you need to bag, mulch or side-discharge the clippings. This roundup compares five push mowers from our product data pack, using only what each listing states, and it notes where a listing title and its bullets do not agree.
Quick answer
- For a cordless, battery-powered push mower with a 21-inch deck, the Greenworks 80V 21in Push Lawn Mower has the widest cutting deck in this group.
- For a gas push mower with self-propelled drive and a large 50-liter bag, the Shulemin 3 in 1 Self Propelled Gas Lawn Mower is the option this group lists for medium to large lawns.
- For a gas walk-behind with an 18-inch steel deck and five height settings, the PowerSmart EasyCut 18-Inch Gas Lawn Mower fits a middle-size lawn.
- For smaller patches or a manual option, the MZK and DREAMADE mowers are compact choices, and the listings describe them that way.
How to decide what “large” means for your yard
Yard size is only one part of the choice. The cutting width sets how many passes you need on open grass, but the deck width also has to fit between flower beds, fences and tree trunks. A 21-inch deck saves time on a wide, open lawn, while a narrower deck is easier to steer around obstacles. Most of the mowers below state a cutting width or deck size in their listing, so you can compare those numbers directly before you choose.
Power source matters just as much. A cordless mower needs a charged battery and a charging routine, and its run time depends on grass conditions and how you use the mower. A gas mower needs fuel and oil, but it does not depend on battery capacity. The listings in this group include both types, so the table below lists what each one says about its power source. When you compare a cordless listing with a gas listing, look at the battery pack that comes with the mower, the charger, and whether a second battery is an extra purchase. For a gas listing, look at the engine size, the fuel tank and the oil the manufacturer recommends, since those decide how often you refuel during a long mowing session.

Greenworks 80V 21in Push Lawn Mower
This is the only cordless model in the group with a 21-inch deck, and its listing is written for larger yards. The deck is the widest in this roundup, so it covers more grass with each pass. The listing states a brushless motor, which it says gives more torque, quieter operation and longer life, and it says the mower runs with no gas, no oil and no emissions.
The listing says the 80V 4.0Ah battery gives up to 60 minutes of run time, and it adds that run time varies with grass condition and technique. The mower has a single-lever, seven-position height adjustment and a three-in-one system for mulching, rear bagging and side discharge. Start is push-button. The box includes the mower, a grass collection bag, the battery, a rapid charger and the operator’s manual. This is the right fit if you want a large deck without a fuel tank, and if you already plan to keep a charged spare battery on hand for bigger jobs.
Shulemin 3 in 1 Self Propelled Gas Lawn Mower
The Shulemin is a gas mower with self-propelled drive, which means the rear wheels move the mower forward so you only steer it. The listing presents it for medium to large lawns, and it highlights traction on slopes and uneven ground. Its 131cc four-stroke engine is described as quieter and more fuel-efficient than two-stroke models, and the listing also points out a simple pull start design.
The mower gives three ways to handle clippings: mulch, bag with the 50-liter catcher, or side discharge. The listing emphasizes the large bag as a way to reduce how often you stop to empty it. The bullets advise cutting dry grass, cleaning the deck after use and not tilting the mower when starting it. The listing does not state a cutting width in its bullets, so if deck width is your main test, look for that number on the product page before you order. For a larger lawn where you want to mow without pushing, this is the most distinct option in the group.
PowerSmart EasyCut 18-Inch Gas Lawn Mower
The PowerSmart is a walk-behind gas push mower with an 18-inch steel deck. Its listing says it is ideal for small yards, which is worth knowing even though the deck is wide. Compared with the Shulemin, it does not drive itself, so you do the pushing. The listing describes a 144cc four-cycle overhead valve engine with auto choke and a primer for easier starting, and it names a pull cord start.
Several listing specs help with sizing. The listing gives a cutting width of 18 inches, a five-position height adjustment from 1.5 to 3.9 inches, and a folded size of 26 by 19 by 14 inches. It also states an item weight of 58.4 pounds, which is heavy enough that many owners will want self-propelled drive on a large lawn. The side discharge throws clippings out the side, and the listing says the 8-inch rear and 7-inch front wheels help with turning around trees and flower beds. The listing shows a recommended oil type of 10W-30 and a fuel tank capacity of 0.21 gallon, which is a small tank, so plan refueling on bigger jobs. The listing title does not use the word “large” for this mower, and its bullets describe it as ideal for small yards, so treat it as a middle-size choice rather than a large-deck machine. It is a sensible pick when the lawn is medium sized and you want a gas engine without the cost of a self-propelled model.
MZK 20V 10-Inch Lawn Mower
The MZK is the smallest deck in this group. Its title says 10 inches, and its subtitle describes it as a compact push mower with dual batteries, three cutting heights and a grass bag, “for large lawns and spaces.” That phrase is marketing language and does not change the deck size, so a 10-inch deck will take more passes than the 18-inch and 21-inch options. It makes sense for a small lawn, a side yard, or a second mower for edges and tight spaces.
The listing states a brushless motor, with 2,800 RPM on low and 3,400 RPM on high. The dual batteries and the 20V platform are named in the title and subtitle, and the listing gives three cutting heights. It does not state the battery capacity in the bullets, so check the product page for the amp-hour rating before you compare run time with the other cordless mower in this roundup. If you want a large deck, skip this one. If you have a compact yard and want to avoid gas, it is a reasonable choice.
DREAMADE Manual Reel Mower, 14″ Push Reel Lawn Mower
The DREAMADE is a manual reel mower, so it has no motor and no battery. Reel mowers cut by scissor action between a rotating blade set and a fixed bar, which is why they are quiet and need no fuel. The listing states five manganese steel blades, which it says offer hardness and edge retention on tough grass. The mower weighs 28 pounds according to the bullets, and the listing describes a flexible rear and front wheel arrangement for stability.
There is a sizing point to check here. The title says 14 inches, but the bullets describe an upgraded 18-inch five-blade reel system and a wider deck. Those two numbers do not match, so confirm the cutting width on the product page before you buy. The height adjustment is on the rear wheels with a gear system, and the grass catcher bag is included. A reel mower works best on a fairly level, lightly grown lawn, and it is not a fit for thick or long grass. For a large yard with light grass and a manual preference, it can work, but it is a different tool from the powered mowers above.
Review: Greenworks 80V 21in as the main pick
If you asked us to choose one mower from this group for a big open yard, we would start with the Greenworks 80V 21in. Its 21-inch deck is the widest listed here, and the listing gives a clear run-time figure for the 4.0Ah battery. The three-in-one system covers mulching, bagging and side discharge, so you do not need a separate mower for each job. The listing also describes push-button start, which is easier on the hands than a pull cord.
The trade-off is battery planning. A single battery covers the run time the listing states, but a large yard may need a second battery or a pause to recharge. The listing does not say whether a spare battery is included, so check that before you order. Compared with the Shulemin and PowerSmart, this mower also drops the fuel and oil routine entirely, which many homeowners see as a practical benefit. Compared with the DREAMADE reel mower, it is faster and more suited to grass that has grown past a light trim. The mower is a good match if your priority is a wide cut with no gas.
FAQ
What is the widest cutting deck in this group?
The Greenworks 80V 21in Push Lawn Mower has the widest listed deck at 21 inches. The PowerSmart lists 18 inches, and the DREAMADE bullets describe an 18-inch reel system while its title says 14 inches. The Shulemin bullets do not state a width, so check its product page.
Is a self-propelled mower better for a large lawn?
Self-propelled drive reduces the effort of pushing across a big yard, especially on slopes. The Shulemin lists self-propelled rear-wheel drive. The PowerSmart is a manual push mower and its listing gives an item weight of 58.4 pounds, so pushing it across a large lawn is a workout. Choose based on your slope and how much pushing you want to do.
Can a reel mower handle a large yard?
A reel mower can cover a large lawn if the grass is kept short and the ground is fairly level. Its listing describes a 28-pound weight and a grass catcher. It does not state a maximum grass height, so keep the mowing frequent and the grass light. For thick or long grass, a powered mower is a better match.
Do the cordless mowers need a charger and battery in the box?
The Greenworks listing says the box includes the mower, a grass collection bag, an 80V 4.0Ah battery, a rapid charger and the operator’s manual. The MZK listing names dual batteries in its subtitle, but the bullets do not list what comes in the box, so check the product page for the included items.
Which mower suits a smaller yard?
The MZK 10-inch is the smallest deck here and is the most compact option. The listing describes three cutting heights and a grass bag. A smaller deck is easier to steer in tight spaces and takes more passes on open grass.
Bottom line
Pick the Greenworks 80V 21in if you want the widest cut and a cordless mower with a stated 60-minute run time on one battery. Pick the Shulemin if you want a gas mower with self-propelled drive and a 50-liter bag. Pick the PowerSmart if you want a manual gas push mower with an 18-inch deck and five height settings. Use the MZK for a compact yard and the DREAMADE reel mower for light grass with no engine. In every case, confirm the cutting width and battery details on the product page, since some listings in this group do not state them in the bullets.
