What Size Mower for 1.5 Acres With Trees? Zero-Turn Deck Size
Quick answer
An acre and a half with trees needs a 36 to 42 inch zero-turn, one deck size smaller than an open lot. A 42 inch zero-turn takes about 1 hr 4 min around trees and beds. The EGO Z6 ZT4204L, rated for 2 acres per charge, leaves a margin for the stop-and-go work.
On an open 1.5 acres, a 48 inch deck is a fine choice. With trees, the recommendation drops to 36 to 42 inches and switches firmly to a zero-turn. The narrower deck fits between trunks, and pivot steering circles each tree in one motion instead of the loop or back-up a tractor needs. The same 42 inch deck takes about 1 hr 32 min on a tractor here and about 1 hr 4 min on a zero-turn.
For battery riders, trees raise a separate question: whether the range still holds up with constant stops, pivots and tight turns.

How long does it take to mow 1.5 acres with trees?
| Mower | Time per mow | Fit for this lawn |
|---|---|---|
| 21 in walk-behind | 4 hr 37 min | Slow for this size |
| 30 in rider | 2 hr 9 min | Slow for this size |
| 42 in lawn tractor | 1 hr 32 min | Recommended |
| 46 in lawn tractor | 1 hr 24 min | Larger than needed |
| 48 in zero-turn | 56 min | Larger than needed |
| 54 in zero-turn | 50 min | Larger than needed |
| 60 in zero-turn | 45 min | Larger than needed |
Recommended deck: 36 to 42 inches, zero-turn (tight turning around trees and beds), one deck size smaller. Times assume typical cutting speeds (3 mph walk-behind, 4.5 mph tractor, 6.5 mph zero-turn), a 15 percent overlap and 60 percent efficiency for this terrain.
Is an electric zero turn enough for 1.5 acres with trees?
Battery ratings are given in acres under normal conditions. Stop-and-go driving around trunks uses energy without covering much ground, so treat any rating that only just matches your lot as having no margin.
| 42 in rider | Rated coverage | 1.5 acres as share of rating | Time per mow here | Verdict |
|---|---|---|---|---|
| EGO POWER+ Z6 ZT4214L 42 in. Electric Zero Turn Mower | 1.5 acres | 100 percent | 1 hr 4 min | No margin; expect to recharge on busy lots |
| EGO POWER+ T6 TR4204 42 in. Electric Lawn Tractor (tractor) | 1.5 acres | 100 percent | 1 hr 32 min | No margin, and slower around trees |
| EGO POWER+ Z6 ZT4204L 42 in. Electric Zero Turn Mower | 2 acres | 75 percent | 1 hr 4 min | Workable margin |
| EGO POWER+ Z6 e-Steer ZT4215S 42 in. Electric Zero Turn Mower | 2 acres | 75 percent | 1 hr 4 min | Workable margin, steering wheel |
| Greenworks 60V CrossoverZ 42 in. Electric Zero Turn Mower | 2.5 acres | 60 percent | 1 hr 4 min | Most margin, lowest price |
| Husqvarna Z242F Special Edition 42 in. Zero Turn Mower | Gas, refuel | n/a | 1 hr 4 min | No range limit |
Coverage ratings are manufacturer figures. Times use 6.5 mph for zero-turns and 4.5 mph for tractors at 60 percent efficiency. The verdict column is our reading of the margin, not a manufacturer claim.
What size zero turn mower for 1.5 acres with trees?
A 42 inch deck. It is the top of the computed range and the smallest common zero-turn. The Husqvarna Z248F 48 in. Zero Turn Mower is listed by Husqvarna for mid-size lawns with trees and beds, but at 48 inches it is one size above this page's range, so choose it only if your gaps are at least about 60 inches. Measure the tightest gap you mow through. A 42 inch zero-turn needs about 54 inches.
How much time does trimming add on 1.5 acres of trees?
As an estimate, about 45 seconds per trunk. With 30 trees, that is about 22 minutes, roughly a third of the time spent mowing. Mulch rings reduce it to about 5 minutes. Rings 6 feet across and 3 inches deep take about 0.26 cubic yards each, or about 7.9 cubic yards for 30 trees, which is usually cheaper delivered in bulk than bagged. Size it with the mulch calculator. Grouping close trees into one bed cuts turning time as well as trimming time.
What leaf gear does a treed 1.5 acres need?
A battery backpack blower like the EGO Power+ LB6003 600 CFM Backpack Blower Kit with 7.5Ah Battery shares a platform with an EGO mower and clears beds quietly. For open lawn, a tow sweeper collects leaves fastest, but it needs a machine designed to tow. The EGO POWER+ T6 TR4204 42 in. Electric Lawn Tractor lists a rear hitch, and many zero-turns do not allow towing. Otherwise, mulch light leaf layers with the mower, or bag them with the EGO POWER+ ABK4200 Bagger Kit for 42 in. Z6 Zero Turn on a ZT4204L. See the best battery leaf blowers and best lawn sweepers.
Is a robot mower practical for 1.5 acres with trees?
Only with care. Few robots are rated for 1.5 acres, and tree canopy can block the satellite positioning most large-area models rely on. The Husqvarna Automower 440iQ Robot Mower is rated for 2 acres, but check how your trees affect its signal first. Many owners on treed lots pair a smaller robot for the shaded front yard with a zero-turn for the rest. See robot mower size for 1.5 acres.

Frequently asked questions
How long does it take to mow 1.5 acres with trees?
About 1 hr 4 min with a 42 inch zero-turn and about 1 hr 32 min with a 42 inch lawn tractor, at 60 percent efficiency for obstacles. An open 1.5 acres with the same zero-turn takes about 48 minutes. Trimming around 30 trees adds an estimated 22 minutes without mulch rings, or about 5 minutes with them.
Will an EGO zero turn mow 1.5 acres of trees on one charge?
The EGO Z6 ZT4204L, rated for 2 acres, should have a workable margin, since a treed 1.5 acres uses about three quarters of its rated coverage before the extra energy of stops and pivots. The ZT4214L is rated for exactly 1.5 acres, so it has no margin on a busy lot. Charging overnight and mowing dry grass help range.
Why is a smaller deck recommended for yards with trees?
Narrow gaps and tight turns cancel the advantage of a wide deck. A 42 inch zero-turn needs about 54 inches between obstacles, while a 54 inch deck needs about 66. On a treed lot, the wider machine spends its time backing out of spaces it cannot pass. The recommended range drops one size, here to 36 to 42 inches.
