What the specs work out to

Figures MowerFacts computes from Spartan’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 acres23 min 16 min
  • 5 acres58 min 41 min
  • 10 acres1 h 56 min 1 h 21 min

About 12 min per acre at 5.18 acres/hour, mowing at 10.5 mph. The second figure is at the published 15.0 mph top speed (7.39 acres/hour) — faster than anyone really mows. About 88.1 acres per tank.

Weight & hauling

  • Machine weight1,310 lb
  • + 6×12 trailer900 lb
  • Towed weight2,210 lb
  • single-axle 3,500 lbCarries it, 1,290 lb spare
  • tandem-axle 7,000 lbCarries it, 4,790 lb spare

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 2,210 lb.

Gate & trailer fit

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

Needs at least 67 in of clearance (estimated).

Power & run time

  • Power per deck inch0.656 hp/in
  • Run time per tank~17.0 h

Mowing times assume 5.18 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 Spartan 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 Spartan 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 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.

What size trailer do I need for the Spartan Spartan KGZ-XD?

That is within a single-axle 3,500 lb trailer, and your tow vehicle needs to be rated for at least 2,210 lb.
