What the specs work out to

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

Mowing time

  • ¼ acre4 min 3 min
  • ½ acre9 min 6 min
  • 1 acre18 min 12 min
  • 2 acres36 min 25 min
  • 5 acres1 h 29 min 1 h 2 min
  • 10 acres2 h 59 min 2 h 5 min

About 18 min per acre at 3.36 acres/hour, mowing at 7.7 mph. The second figure is at the published 11.0 mph top speed (4.8 acres/hour) — faster than anyone really mows. About 31.9 acres per tank.

Weight & hauling

  • Machine weight1,108 lb
  • + 6×12 trailer900 lb
  • Towed weight2,008 lb
  • single-axle 3,500 lbCarries it, 1,492 lb spare
  • tandem-axle 7,000 lbCarries it, 4,992 lb spare

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 2,008 lb.

Gate & trailer fit

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

Needs at least 56 in of clearance.

Power & run time

  • Power per deck inch0.5 hp/in
  • Run time per tank~9.5 h

Mowing times assume 3.36 acres/hour: deck width x 7.7 mph at 80% efficiency, which allows for overlap, turns and trimming. 7.7 mph is 70% of the 11.0 mph top speed Spartan publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 11.0 mph, shown so you can see it.

Fit uses Spartan's published overall width.

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