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

- ½ acre16 min 11 min
- 1 acre33 min 23 min
- 2 acres1 h 5 min 46 min
- 5 acres2 h 44 min 1 h 55 min
About 33 min per acre at 1.83 acres/hour, mowing at 6.3 mph. The second figure is at the published 9.0 mph top speed (2.62 acres/hour) — faster than anyone really mows. About 9.3 acres per tank.

- tandem-axle 7,000 lbCarries it, 5,300 lb spare
Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 1,700 lb.
Gate & trailer fit

Needs at least 42 in of clearance (estimated).
Power & run time
- Power per deck inch0.528 hp/in
- Run time per tank~5.1 h
Mowing times assume 1.83 acres/hour: deck width x 6.3 mph at 80% efficiency, which allows for overlap, turns and trimming. 6.3 mph is 70% of the 9.0 mph top speed Bobcat publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 9.0 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because Bobcat 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 Bobcat'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.
