What the specs work out to

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

Mowing time

  • ¼ acre12 min 8 min
  • ½ acre24 min 17 min
  • 1 acre47 min 33 min
  • 2 acres1 h 35 min 1 h 6 min
  • 5 acres3 h 57 min 2 h 46 min

About 47 min per acre at 1.26 acres/hour, mowing at 3.9 mph. The second figure is at the published 5.6 mph top speed (1.81 acres/hour) — faster than anyone really mows.

Weight & hauling

  • Machine weight417 lb
  • + 6×12 trailer900 lb
  • Towed weight1,317 lb
  • single-axle 3,500 lbCarries it, 2,183 lb spare
  • tandem-axle 7,000 lbCarries it, 5,683 lb spare

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 1,317 lb.

Gate & trailer fit

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

Needs at least 46 in of clearance (estimated).

Power & run time

  • Power per deck inch0.45 hp/in

Mowing times assume 1.26 acres/hour: deck width x 3.9 mph at 80% efficiency, which allows for overlap, turns and trimming. 3.9 mph is 70% of the 5.6 mph top speed Cox publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 5.6 mph, shown so you can see it.

Fit uses the deck width plus 6 in for the discharge chute, because Cox 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 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.
