What the specs work out to

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

Mowing time

  • ¼ acre3 min 2 min
  • ½ acre6 min 4 min
  • 1 acre12 min 8 min
  • 2 acres24 min 16 min
  • 5 acres59 min 41 min
  • 10 acres1 h 58 min 1 h 22 min

About 12 min per acre at 5.09 acres/hour, mowing at 10.5 mph. The second figure is at the published 15.0 mph top speed (7.27 acres/hour) — faster than anyone really mows. About 63.6 acres per tank.

Weight & hauling

  • Machine weight1,586 lb
  • + 6×12 trailer900 lb
  • Towed weight2,486 lb
  • single-axle 3,500 lbCarries it, 1,014 lb spare
  • tandem-axle 7,000 lbCarries it, 4,514 lb spare

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 2,486 lb.

Gate & trailer fit

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

Needs at least 66 in of clearance (estimated).

Power & run time

  • Power per deck inch0.583 hp/in
  • Run time per tank~12.5 h

Mowing times assume 5.09 acres/hour: deck width x 10.5 mph at 80% efficiency, which allows for overlap, turns and trimming. 10.5 mph is 70% of the 15.0 mph top speed Gravely publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 15.0 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.

Gravely PRO-TURN 660 KAWASAKI questions

What size deck is on the Gravely PRO-TURN 660 KAWASAKI?

The Gravely PRO-TURN 660 KAWASAKI has a 60-inch (1524 mm) cutting deck with 7 ga construction.

What engine is in the Gravely PRO-TURN 660 KAWASAKI?

The Gravely PRO-TURN 660 KAWASAKI is powered by a Kawasaki® FX1000, 1000 cc, 35 hp. Horsepower is the manufacturer's own rating.

How much does the Gravely PRO-TURN 660 KAWASAKI weigh?

The Gravely PRO-TURN 660 KAWASAKI weighs 1,586 lb (719.4 kg) as specified by Gravely.

What size trailer do I need for the Gravely PRO-TURN 660 KAWASAKI?

At 1,586 lb, the Gravely PRO-TURN 660 KAWASAKI on a typical 6x12 open utility trailer (about 900 lb empty) is roughly 2,486 lb of towed weight. That is within a single-axle 3,500 lb trailer, and your tow vehicle needs to be rated for at least 2,486 lb. Tongue weight, axle placement and your own trailer's empty weight still have to be checked — this is the arithmetic, not a loading plan.

How fast is the Gravely PRO-TURN 660 KAWASAKI?

Top ground speed is 15 mph. With its 60-inch deck that works out to about 7.27 acres per hour at 80% efficiency — allowing for overlap, turns and trimming.

How long does the Gravely PRO-TURN 660 KAWASAKI take to mow an acre?

About 8 min per acre, from its 60-inch deck at 15 mph and 80% efficiency — roughly 7.27 acres an hour, so five acres is about 41 min. Rough or obstacle-heavy ground takes longer; this is deck width times ground speed, not a timed test.

The Gravely PRO-TURN 660 KAWASAKI holds 12.5 gal (47.3 L) of fuel.
