What the specs work out to

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

Mowing time

  • ¼ acre7 min 5 min
  • ½ acre15 min 10 min
  • 1 acre30 min 21 min
  • 2 acres59 min 41 min
  • 5 acres2 h 28 min 1 h 44 min
  • 10 acres4 h 56 min 3 h 27 min

About 30 min per acre at 2.03 acres/hour, mowing at 5.2 mph. The second figure is at the published 7.5 mph top speed (2.89 acres/hour) — faster than anyone really mows. About 17.3 acres per tank.

Weight & hauling

  • Machine weight628 lb
  • + 6×12 trailer900 lb
  • Towed weight1,528 lb
  • single-axle 3,500 lbCarries it, 1,972 lb spare
  • tandem-axle 7,000 lbCarries it, 5,472 lb spare

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 1,528 lb.

Gate & trailer fit

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

Needs at least 44 in of clearance.

Power & run time

  • Power per deck inch0.479 hp/in
  • Run time per tank~8.5 h

Mowing times assume 2.03 acres/hour: deck width x 5.2 mph at 80% efficiency, which allows for overlap, turns and trimming. 5.2 mph is 70% of the 7.5 mph top speed Cox publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 7.5 mph, shown so you can see it.

Fit uses Cox's published overall width.

Towed weight adds a 900 lb allowance for a 6x12 open utility trailer to Cox'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.
