What the specs work out to

Figures MowerFacts computes from Gravely’s own numbers — not published by the manufacturer.

Mowing time

  • ¼ acre13 min 9 min
  • ½ acre26 min 18 min
  • 1 acre52 min 36 min
  • 2 acres1 h 44 min 1 h 13 min
  • 5 acres4 h 20 min 3 h 2 min

About 52 min per acre at 1.15 acres/hour, mowing at 4.2 mph. The second figure is at the published 6.0 mph top speed (1.65 acres/hour) — faster than anyone really mows. About 2.3 acres per tank.

Weight & hauling

  • Machine weight445 lb
  • + 6×12 trailer900 lb
  • Towed weight1,345 lb
  • single-axle 3,500 lbCarries it, 2,155 lb spare
  • tandem-axle 7,000 lbCarries it, 5,655 lb spare

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 1,345 lb.

Gate & trailer fit

  • 32 in gateToo wide
  • 36 in gateToo wide
  • 48 in gateFits

Needs at least 41 in of clearance (estimated).

Power & run time

  • Power per deck inch0.529 hp/in
  • Run time per tank~2.0 h

Mowing times assume 1.15 acres/hour: deck width x 4.2 mph at 80% efficiency, which allows for overlap, turns and trimming. 4.2 mph is 70% of the 6.0 mph top speed Gravely publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 6.0 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.
