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

- 1 acre16 min 11 min
- 2 acres33 min 23 min

About 16 min per acre at 3.67 acres/hour, mowing at 8.4 mph. The second figure is at the published 12.0 mph top speed (5.24 acres/hour) — faster than anyone really mows. About 47.7 acres per tank.

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 2,157 lb.
Gate & trailer fit

Needs at least 61 in of clearance (estimated).
Power & run time
- Power per deck inch0.463 hp/in
- Run time per tank~13.0 h
Mowing times assume 3.67 acres/hour: deck width x 8.4 mph at 80% efficiency, which allows for overlap, turns and trimming. 8.4 mph is 70% of the 12.0 mph top speed Bad Boy Mowers publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 12.0 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because Bad Boy Mowers 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 Bad Boy Mowers'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.
