What the specs work out to
Figures MowerFacts computes from Gravely’s own numbers — not published by the manufacturer.
Mowing time
- ¼ acre6 min 4 min
- ½ acre13 min 9 min
- 1 acre25 min 18 min
- 2 acres51 min 36 min
- 5 acres2 h 7 min 1 h 29 min
- 10 acres4 h 15 min 2 h 58 min
About 25 min per acre at 2.35 acres/hour, mowing at 5.6 mph. The second figure is at the published 8.0 mph top speed (3.36 acres/hour) — faster than anyone really mows. About 12.0 acres per tank.

- tandem-axle 7,000 lbCarries it, 5,283 lb spare
Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 1,717 lb.
Gate & trailer fit

- 36 in gateToo wide
- 48 in gateToo wide
Needs at least 59 in of clearance (estimated).
Power & run time
- Power per deck inch0.442 hp/in
- Run time per tank~5.1 h
Mowing times assume 2.35 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.
