What Size Mower for 1.5 Acres? Deck Size, Gate Width and Time
Quick answer
An acre and a half needs a 42 to 48 inch lawn tractor or zero-turn. A 46 inch lawn tractor mows an open 1.5 acres in about 1 hr 3 min, and a 48 inch zero-turn in about 42 minutes. Measure your gate first, because a 48 inch deck needs roughly 60 inches of clearance.
At 1.5 acres (65,340 square feet), deck size starts to matter. A 30 inch rider that works on a smaller lot now needs about 1 hr 37 min. Stepping up to 42 to 48 inches brings the job to around an hour or less. The limits are usually physical rather than financial: the width of the gate between the front and back yard, and the door of the shed or garage where the mower lives.
This page focuses on those limits, plus the tractor versus zero-turn and gas versus battery choices at this size. Run your exact lawn through the mower deck size calculator.

| Mower | Time per mow | Fit for this lawn |
|---|---|---|
| 21 in walk-behind | 3 hr 28 min | Slow for this size |
| 30 in rider | 1 hr 37 min | Slow for this size |
| 42 in lawn tractor | 1 hr 9 min | Recommended |

Recommended deck: 42 to 48 inches, lawn tractor or zero-turn. Times assume typical cutting speeds (3 mph walk-behind, 4.5 mph tractor, 6.5 mph zero-turn), a 15 percent overlap and 80 percent efficiency for this terrain.
Will a 48 inch mower fit through my gate?
A mower's overall width is roughly 6 to 12 inches more than its deck once you count the discharge chute, wheels and deck rollers. This table uses the wider figure for planning, plus season hours for an open 1.5 acres.
| Deck | Overall width (approx.) | Plan a gate of at least | Time per mow | 26 mows | 32 mows |
|---|---|---|---|---|---|
| 42 in lawn tractor | 48 to 54 in | 54 in | 1 hr 9 min | 30 hr | 37 hr |
| 42 in zero-turn | 48 to 54 in | 54 in | 48 min | 20.8 hr | 25.6 hr |
| 46 in lawn tractor | 52 to 58 in | 60 in | 1 hr 3 min | 27.4 hr | 33.8 hr |
| 48 in zero-turn | 54 to 60 in | 60 in | 42 min | 18.2 hr | 22.4 hr |
| 54 in zero-turn (one size larger) | 60 to 66 in | 66 in | 37 min | 16.2 hr | 19.9 hr |
Width ranges are planning allowances, not model specifications. Check the operator manual or listing for exact overall width with the chute down. Times use 4.5 mph tractors and 6.5 mph zero-turns at 80 percent efficiency.
What size riding mower do I need for 1.5 acres?
A 42 to 48 inch deck. Among lawn tractors, the Husqvarna TS 120 46 in. Lawn Tractor at $3,185.00 is the best fit. Among zero-turns, the Husqvarna Z248F 48 in. Zero Turn Mower has a 48 inch fabricated 3-blade deck and a Hydro-Gear ZT-2200 transmission. If your gate is 54 inches or narrower, stay at 42 inches, which adds only about 6 minutes a mow on a zero-turn compared with the 48. A 54 inch deck saves another 5 minutes but needs about a 66 inch opening.
Lawn tractor or zero turn for 1.5 acres?
On an open 1.5 acres, a 48 inch zero-turn saves about 21 minutes per mow over a 46 inch tractor, or about 9 hours over a 26 mow season. That is a real difference, and it grows as the lot gets busier with beds. A tractor still wins on towing, a steering wheel and slopes. If the land is hilly, see 1.5 acres with hills. The full trade-off is on zero-turn vs lawn tractor.
Can an electric riding mower mow 1.5 acres on one charge?
Choose one rated above 1.5 acres. The EGO POWER+ T6 TR4204 42 in. Electric Lawn Tractor and EGO POWER+ Z6 ZT4214L 42 in. Electric Zero Turn Mower are each rated for exactly 1.5 acres per charge, which leaves no margin for thick grass. The EGO POWER+ Z6 ZT4204L 42 in. Electric Zero Turn Mower and EGO POWER+ Z6 e-Steer ZT4215S 42 in. Electric Zero Turn Mower are rated for 2 acres, and the Greenworks 60V CrossoverZ 42 in. Electric Zero Turn Mower for 2.5 acres. Any of those three can finish an open 1.5 acres on a single charge with some range to spare. Compare running costs in the gas vs battery cost calculator.
How much storage does a 46 or 48 inch mower need?
Plan a parking space of about 5 by 7 feet for a 46 or 48 inch rider, with room to walk around it. A shed door needs the same clearance as the gate, so a 60 inch opening is a sensible minimum. The shed size for a zero-turn mower page lists floor sizes and door widths. For blade service at home, the MoJack EZ MAX 45001 Riding Mower Lift lifts tractors and zero-turns with an 18.5 to 47.5 inch wheel span.

Frequently asked questions
What deck size do I need for 1.5 acres?
A 42 to 48 inch deck. A 46 inch lawn tractor takes about 1 hr 3 min on an open 1.5 acres, a 42 inch zero-turn about 48 minutes and a 48 inch zero-turn about 42 minutes. Smaller decks add real time here, as a 30 inch rider needs about 1 hr 37 min. Check your narrowest gate before choosing 48 inches.
How wide does a gate need to be for a riding mower?
Plan for the deck width plus 6 to 12 inches. A 42 inch mower typically needs a 48 to 54 inch opening with the chute down, a 48 inch mower 54 to 60 inches and a 54 inch mower 60 to 66 inches. Some chutes fold up to save a few inches. The listing or operator manual gives the exact overall width.
Is a 42 inch zero turn big enough for 1.5 acres?
Yes. A 42 inch zero-turn mows an open 1.5 acres in about 48 minutes, and it is inside the recommended 42 to 48 inch range. A 48 inch deck saves about 6 minutes per mow, or roughly 2.6 hours over 26 mows. If your gate is narrow or your storage is tight, the 42 inch deck is the sensible choice.
