What the specs work out to
Figures MowerFacts computes from Spartan’s own numbers — not published by the manufacturer.

- 1 acre28 min 19 min
- 2 acres55 min 39 min
- 5 acres2 h 18 min 1 h 37 min

About 28 min per acre at 2.17 acres/hour, mowing at 5.6 mph. The second figure is at the published 8.0 mph top speed (3.1 acres/hour) — faster than anyone really mows. About 10.8 acres per tank.

Power & run time
- Power per deck inch0.479 hp/in
- Run time per tank~5.0 h
Mowing times assume 2.17 acres/hour: deck width x 5.6 mph at 80% efficiency, which allows for overlap, turns and trimming. 5.6 mph is 70% of the 8.0 mph top speed Spartan publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 8.0 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.
