What the specs work out to
Figures MowerFacts computes from Exmark’s own numbers — not published by the manufacturer.
Mowing time
- ¼ acre8 min 6 min
- ½ acre16 min 11 min
- 1 acre32 min 22 min
- 2 acres1 h 3 min 44 min
- 5 acres2 h 38 min 1 h 50 min
About 32 min per acre at 1.9 acres/hour, mowing at 4.9 mph. The second figure is at the published 7.0 mph top speed (2.72 acres/hour) — faster than anyone really mows. About 14.2 acres per tank.
Gate & trailer fit

- 36 in gateToo wide
- 48 in gateToo wide
Needs at least 54 in of clearance (estimated).
Power & run time
- Power per deck inch0.552 hp/in
- Run time per tank~7.5 h
Mowing times assume 1.9 acres/hour: deck width x 4.9 mph at 80% efficiency, which allows for overlap, turns and trimming. 4.9 mph is 70% of the 7.0 mph top speed Exmark publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 7.0 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because Exmark doesn't publish an overall width — measure before buying if a gate is tight.
Run time assumes a typical 1 gal/hour burn at working load; real consumption varies with engine, load and cut.
