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

- ½ acre28 min 19 min
- 1 acre55 min 39 min
- 2 acres1 h 50 min 1 h 17 min
- 5 acres4 h 36 min 3 h 13 min
About 55 min per acre at 1.09 acres/hour, mowing at 4.2 mph. The second figure is at the published 6.0 mph top speed (1.55 acres/hour) — faster than anyone really mows. About 6.0 acres per tank.

Needs at least 39 in of clearance (estimated).
Power & run time
- Power per deck inch0.437 hp/in
- Run time per tank~5.5 h
Mowing times assume 1.09 acres/hour: deck width x 4.2 mph at 80% efficiency, which allows for overlap, turns and trimming. 4.2 mph is 70% of the 6.0 mph top speed Scag publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 6.0 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because Scag 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 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.
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 Scag SW Belt-Drive?
At 450 lb, the Scag SW Belt-Drive on a typical 6x12 open utility trailer (about 900 lb empty) is roughly 1,350 lb of towed weight. That is within a single-axle 3,500 lb trailer, and your tow vehicle needs to be rated for at least 1,350 lb.
