Choose a wider deck if you want to walk
For about ½ acre of grass, a self-propelled mower can work, but you’ll be doing plenty of walking. We’d choose at least a 25 in. deck and compare 30 in. models if your gates allow. Prefer to sit? A compact tractor is worth considering.

From lawns measured on MeasureLawn
81% of measured lawns are smaller than half an acre
On MeasureLawn, people trace the grass itself on satellite imagery, with the house, driveway, beds and patios cut out. 81% of the lawns measured that way are smaller than half an acre.
The lot size on a listing or tax record overstates the grass you mow, so size a mower from the measured lawn. 16% of these lawns had flower beds marked when they were measured (1,351 sq ft of beds on the typical one); beds add edging time whichever mower you choose.

How long it takes to mow a half-acre
Estimated for 21,780 sq ft of grass. A wider deck means fewer passes; riding saves the walk as well.
| Mower | Deck | Mowing time |
|---|---|---|
| Walk-behind (push or self-propelled) | 21 in | about 1 hr |
| Walk-behind (push or self-propelled) | 25 in | about 50 min |
| Walk-behind (push or self-propelled) | 30 in | about 40 min |
| Lawn tractor | 42 in | about 25 min |
| Lawn tractor | 46 in | about 20 min |
| Zero-turn | 42 in | about 15 min |
| Zero-turn | 54 in | about 10 min |
A robotic mower works on its own schedule, so the question is its rated area and slope limit rather than mowing time.
How we estimate: each pass overlaps the last by 10%, plus 15% for turns and edges, at a steady 3 mph walking, 4 mph on a lawn tractor and 6 mph on a zero-turn. Obstacles, slopes, tall grass and battery swaps add time. Measure your lawn to work it out for your own grass.
Measure your real lawn before you buy
Your property's lot size includes the house, driveway and flower beds — your actual mowable grass is usually a good bit smaller. Trace your lawn on satellite imagery in a couple of minutes to get the exact square footage, then compare model capacity. Check slope limits and gate clearance separately against the exact machine.

Is a push mower enough for half an acre?
It can cut the grass, but half an acre is about 21,780 sq ft to push and walk. For a walking mower we recommend self-propelled drive with at least a 25-inch deck, ideally around 30 inches if access and storage allow. A tractor or zero-turn avoids walking every pass.
How long does it take to mow half an acre?
For 21,780 sq ft of grass, our estimate is about 1 hr with a 21-inch walk-behind, about 40 min with a 30-inch deck and about 25 min on a 42-inch lawn tractor. That assumes a steady pace, a little overlap between passes and time for turns; obstacles, slopes, tall grass and battery swaps add more. The table on this page shows every assumption.
Self-propelled or riding mower for a half-acre?
Compare a 25–30 inch self-propelled mower if you enjoy walking and want less storage space. Choose a lawn tractor or zero-turn if avoiding a long weekly walk matters more. A tractor offers familiar steering and compatible attachments; a zero-turn suits repeated tight turns. Check access and exact model slope limits.
What's the best battery mower for a half-acre?
For a walking mower, start by comparing 25–30 inch self-propelled models. Check the exact battery kit, usable capacity for your grass and whether batteries and charger are included. A narrow 21–22 inch model can work, but usually means more passes and walking.
