What the specs work out to
Figures MowerFacts computes from Ferris’s own numbers — not published by the manufacturer.
Mowing time
- ¼ acre21 min 15 min
- ½ acre41 min 29 min
- 1 acre1 h 23 min 58 min
- 2 acres2 h 46 min 1 h 56 min
About 83 min per acre at 0.72 acres/hour, mowing at 2.8 mph. The second figure is at the published 4.0 mph top speed (1.03 acres/hour) — faster than anyone really mows. About 0.7 acres per tank.
Gate & trailer fit

- 36 in gateToo wide
- 48 in gateFits
Needs at least 39 in of clearance (estimated).
Power & run time
- Power per deck inch0.319 hp/in
- Run time per tank~1.0 h
Mowing times assume 0.72 acres/hour: deck width x 2.8 mph at 80% efficiency, which allows for overlap, turns and trimming. 2.8 mph is 70% of the 4.0 mph top speed Ferris publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 4.0 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because Ferris 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.
