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

- ½ acre2 min 1 min
- 1 acre3 min 2 min
- 2 acres6 min 4 min

About 3 min per acre at 19.93 acres/hour, mowing at 5.9 mph. The second figure is at the published 8.4 mph top speed (28.48 acres/hour) — faster than anyone really mows. About 99.7 acres per tank.

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 2,223 lb.

Needs at least 48 in of clearance.
Power & run time
- Power per deck inch0.036 hp/in
- Run time per tank~5.0 h
Mowing times assume 19.93 acres/hour: deck width x 5.9 mph at 80% efficiency, which allows for overlap, turns and trimming. 5.9 mph is 70% of the 8.4 mph top speed Kubota publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 8.4 mph, shown so you can see it.
Fit uses Kubota's published overall width.
Towed weight adds a 900 lb allowance for a 6x12 open utility trailer to Kubota'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.
