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

- 2 acres2 h 16 min 1 h 35 min
About 68 min per acre at 0.88 acres/hour, mowing at 2.1 mph. The second figure is at the published 3.0 mph top speed (1.26 acres/hour) — faster than anyone really mows.

Power & run time
- Power per deck inch0.711 hp/in
Mowing times assume 0.88 acres/hour: deck width x 2.1 mph at 80% efficiency, which allows for overlap, turns and trimming. 2.1 mph is 70% of the 3.0 mph top speed Scag publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 3.0 mph, shown so you can see it.
Fit uses Scag's published overall width.
Towed weight adds a 900 lb allowance for a 6x12 open utility trailer to Scag'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.
