What the specs work out to
Figures MowerFacts computes from Husqvarna’s own numbers — not published by the manufacturer.
Mowing time
- ¼ acre36 min 25 min
- ½ acre1 h 12 min 50 min
- 1 acre2 h 23 min 1 h 40 min
- 2 acres4 h 47 min 3 h 21 min
About 143 min per acre at 0.42 acres/hour, mowing at 2.6 mph. The second figure is at the published 3.7 mph top speed (0.6 acres/hour) — faster than anyone really mows.
Gate & trailer fit

- 36 in gateFits
- 48 in gateFits
Needs at least 26 in of clearance (estimated).
Power & run time
- Power per deck inch0.23 hp/in
Mowing times assume 0.42 acres/hour: deck width x 2.6 mph at 80% efficiency, which allows for overlap, turns and trimming. 2.6 mph is 70% of the 3.7 mph top speed Husqvarna publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 3.7 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because Husqvarna doesn't publish an overall width — measure before buying if a gate is tight.
