What the specs work out to
Figures MowerFacts computes from Gravely’s own numbers — not published by the manufacturer.

- 1 acre22 min 15 min
- 2 acres44 min 31 min

About 22 min per acre at 2.72 acres/hour, mowing at 5.6 mph. The second figure is at the published 8.0 mph top speed (3.88 acres/hour) — faster than anyone really mows. About 13.9 acres per tank.

Needs at least 66 in of clearance (estimated).
Power & run time
- Power per deck inch0.4 hp/in
- Run time per tank~5.1 h
Mowing times assume 2.72 acres/hour: deck width x 5.6 mph at 80% efficiency, which allows for overlap, turns and trimming. 5.6 mph is 70% of the 8.0 mph top speed Gravely publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 8.0 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because Gravely doesn't publish an overall width — measure before buying if a gate is tight.
Towed weight adds a 900 lb allowance for a 6x12 open utility trailer to Gravely's published machine weight. Your trailer's own weight is on its VIN plate. Tongue weight, axle placement and your vehicle's tow rating are still yours to check — this is the load, not a loading plan.
Run time assumes a typical 1 gal/hour burn at working load; real consumption varies with engine, load and cut.
