Two acres of grass is a different job from a city lot. It is an afternoon of walking, not a quick pass after dinner, and a push mower turns that walk into a workout. The best self propelled mower for 2 acres takes the pushing out of the equation: the drive wheels carry the machine forward and you steer. This guide compares four self-propelled walk-behind mowers, three battery and one gas, on what their listings state: rated runtime, deck, drive type, cutting heights and warranty.

Our acreage picks
EGO Power+ 21 in 56V Self-Propelled Mower
A 21 in battery self-propelled mower with two batteries in the box, up to 80 minutes of stated runtime, Touch Drive palm control and the longest stated warranty here.
Read the full review
The EGO LM2123SP is the most complete battery package here. The listing states up to 6.0 ft-lbs of cutting torque, up to 80 minutes of runtime on the included 56V 6.0Ah and 4.0Ah batteries, and a 3-in-1 choice of mulching, side discharge or bagging into the included two-bushel bag. Touch Drive engages the self-propel with palm pressure and the speed dial sits at the fingertips, which is the most refined drive control of the four.
The 90-pound weight is the trade: it is the heaviest battery mower here and the deck material is polypropylene, not steel. The warranty is the best stated of the four at 5 years on the tool and 3 years on the battery. For two acres of mixed flat and obstacle ground, the runtime and drive control put it first.
Pros
- Up to 80 minutes of stated runtime, the longest battery figure here
- Two batteries included: 6.0Ah and 4.0Ah with a rapid charger
- Touch Drive self-propelled with a fingertip variable speed dial
- 5-year tool warranty and 3-year battery warranty stated
Cons
- 90 pounds is the heaviest battery model of the four
- Polypropylene deck rather than steel
- Two-bushel bag fills fast on two acres of spring growth
- Charger refills the 6.0Ah battery in 45 minutes, not 30
Greenworks 82V 21 in Self-Propelled Mower
An 82V battery self-propelled mower stating up to 90 minutes of runtime and up to 1.5 acres on a single charge, with a 17K FPM blade tip speed.
Read the full review
The Greenworks 82V leads on stated stamina: up to 90 minutes of runtime and up to 1.5 acres on a single charge, both the highest figures here. The listing pairs that with a constant 17K FPM blade tip speed, a 2.5 kW brushless drive motor it says beats 160cc gas engine competitors, and ground speeds up to 3.5 MPH.
The spec table states cutting heights in centimeters, an odd unit for a US listing, and only one battery comes in the box. The 2-year tool and battery warranty is the shortest battery warranty of the three. It still ranks second on runtime and acreage figures alone.
Pros
- Up to 90 minutes of stated runtime, the longest here
- Up to 1.5 acres on a single charge, stated in the listing
- 17K FPM constant blade tip speed for a clean cut
- Dual port charger refills in as little as 60 minutes
Cons
- 95 pounds is the heaviest of the four
- Cutting heights are stated in centimeters, not inches
- 2-year warranty is shorter than the EGO and the 48V Greenworks
- One 8.0Ah battery in the box, no second battery included
Greenworks 48V 21 in Self-Propelled Mower
A 48V battery self-propelled mower running on two 24V 5Ah batteries, with rear wheel drive, variable speed and a 4-in-1 cutting system.
Read the full review
The Greenworks 48V is the value play in the battery group. Two 24V 5Ah batteries combine for 48V, a dual port charger is included, and the 4-in-1 system adds a turbo button for leaf pickup on top of mulch, rear bagging and side discharge. Self-propelled rear wheel drive with variable speed control suits mixed terrain.
One contradiction to flag: the title says 21 in while the spec table lists a 20.28 in cutting width. Per our rule we trust the title and bullets, so 21 in. The 45-minute stated runtime is the shortest here, which is why it sits third despite the 3-year manufacturer warranty.
Pros
- Two 24V batteries combine for 48V on one battery platform
- Dual port charger included in the box
- Rear wheel drive with variable speed control
- 4-in-1 system: mulch, rear bag, side discharge and turbo button
Cons
- Up to 45 minutes of stated runtime is the shortest here
- Title says 21 in but the spec table lists a 20.28 in cutting width
- 77 pounds with batteries, middling weight
- Runtime varies with grass condition per the listing
PowerSmart 21 in 140cc Gas Self-Propelled Mower
A gas self-propelled mower with a 140cc Briggs and Stratton engine, a 21 in steel deck and 6 cutting heights; the only non-battery pick here.
Read the full review
The PowerSmart is the gas alternative: a 140cc Briggs and Stratton EX550 engine under a 21 in steel deck, with auto choke and recoil start. The listing aims it at large lawns and tough conditions and notes the self-propelled drive helps on uneven terrain. At 70 pounds it is the lightest machine here.
What the listing does not state costs it: no warranty term, no runtime figure and no fuel capacity. The battery picks all publish runtime and warranty; this one publishes neither. It ranks last, but for buyers who want gas power with no battery logistics, it is the only option.
Pros
- 140cc Briggs and Stratton engine, the only gas power here
- 21 in steel deck built for tough conditions
- No battery to charge or swap mid-job
- 70 pounds is the lightest of the four
Cons
- No warranty term is stated in the listing
- No runtime or fuel capacity is stated
- Recoil starter instead of push-button start
- 6 height positions, fewer than the 7 on the battery picks

Buying guide: best self propelled mower for 2 acres
Start with runtime, because two acres is a lot of walking behind a mower. The EGO states up to 80 minutes on its two included batteries, and the Greenworks 82V states up to 90 minutes with up to 1.5 acres on a single charge. The Greenworks 48V states up to 45 minutes on its two 5Ah batteries. Runtime varies with grass condition and operator technique on every one of these, per the listings, so read the stated figure as a best case on easy grass.
Next, the drive. All four are self-propelled, but the type differs: the Greenworks 48V uses self-propelled rear wheel drive with variable speed control, the EGO uses Touch Drive engaged by the palm with a speed dial at the fingertips, the Greenworks 82V states intelligent power with ground speeds up to 3.5 MPH, and the PowerSmart is a gas self-propelled the listing aims at uneven terrain and large yards. Variable speed matters on two acres: you will want a slower pace around beds and a faster one on open straightaways.
Decks are all 21 in here, so the cut width does not separate them. Cutting height range does: the EGO adjusts from 1.25 to 4 in across 7 positions, the Greenworks 48V from 1 to 7 in across 7 positions, and the PowerSmart across 6 positions from 1.5 to 3.9 in. All four offer mulching and bagging, and three add side discharge. The EGO includes a two-bushel grass collection bag.
Then the long view: warranties. The EGO lists a 5-year tool warranty and 3-year battery warranty, the Greenworks 48V a 3-year manufacturer warranty, and the Greenworks 82V a 2-year tool and battery warranty. The PowerSmart listing states no warranty term. For a machine that will mow two acres week after week, a stated warranty is worth real weight.
Lawn size, deck width and speed in; minutes per mow out. Or work backward from the time you want to spend.
Walk the area first and clear stones, sticks, wire and toys. Wear eye and hearing protection, long pants and sturdy closed footwear, mow across slopes with a walk-behind (not up and down), and never pull a running mower toward you. Keep kids and pets well away. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Walk-behind mowers ask for eye and hearing protection, and a clear yard before you start. Pick up sticks, stones and toys: a 21 in deck at full speed turns debris into projectiles. Mow across slopes rather than up and down, keep hands and feet clear of the deck, and shut the machine off before clearing a clogged discharge.
Matching It to Your Property
- Open two acres, mostly flat: the Greenworks 82V with up to 90 minutes of stated runtime and up to 1.5 acres per charge, or the EGO with up to 80 minutes and two batteries in the box.
- Ground with trees and beds to steer around: the EGO with Touch Drive and a fingertip speed dial, or the Greenworks 48V with rear wheel drive and variable speed control.
- Uneven or rough ground: the PowerSmart, whose listing aims it at uneven terrain, with a steel deck and a gas engine that does not watch a battery gauge.
- Tight storage: battery mowers fold down smaller than a gas machine with fuel to store; the Greenworks 48V and EGO both list push-button starts with no fuel, oil or choke.
- Long ownership: the EGO with a 5-year tool warranty, then the Greenworks 48V with a 3-year manufacturer warranty.

FAQ: mowing large lots
Is a self-propelled mower enough for 2 acres?
It removes the pushing, which is the hard part of two acres. These four are all 21 in walk-behinds; the listings state runtimes from 45 to 90 minutes, so plan on at least one battery swap or a gas refill mid-job.
Battery or gas for 2 acres?
Three of these are battery and one is gas. Battery brings push-button starts and no fuel or oil; the gas PowerSmart brings a 140cc Briggs and Stratton engine and a steel deck with no runtime limit beyond the tank. Pick by which trade you prefer.
How long do the batteries last per charge?
Per the listings: up to 80 minutes for the EGO on its 56V 6.0Ah and 4.0Ah batteries, up to 90 minutes for the Greenworks 82V 8.0Ah, and up to 45 minutes for the Greenworks 48V on two 5Ah batteries. All three note runtime varies with grass condition and operator technique.
What cutting heights do these offer?
The EGO adjusts 1.25 to 4 in across 7 positions, the Greenworks 48V 1 to 7 in across 7 positions, and the PowerSmart across 6 positions from 1.5 to 3.9 in. The Greenworks 82V states its heights in centimeters in the spec table.
Do any of these mulch?
Yes, all four. The Greenworks 48V lists a 4-in-1 system with mulch, rear bagging, side discharge and a turbo button; the EGO, PowerSmart and Greenworks 82V each list 3-in-1 mulching, bagging and discharge.
