What the specs work out to
Figures MowerFacts computes from Kubota’s own numbers — not published by the manufacturer.
Mowing time
- ¼ acre5 min 3 min
- ½ acre10 min 7 min
- 1 acre20 min 14 min
- 2 acres39 min 28 min
- 5 acres1 h 38 min 1 h 9 min
- 10 acres3 h 16 min 2 h 18 min
About 20 min per acre at 3.05 acres/hour, mowing at 7.0 mph. The second figure is at the published 10.0 mph top speed (4.36 acres/hour) — faster than anyone really mows. About 20.7 acres per tank.

- Towed weight1,854 lb
- single-axle 3,500 lbCarries it, 1,646 lb spare
- tandem-axle 7,000 lbCarries it, 5,146 lb spare
Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 1,854 lb.
Gate & trailer fit
- 32 in gateToo wide
- 36 in gateToo wide
- 48 in gateToo wide
Needs at least 68 in of clearance.
Power & run time
- Power per deck inch0.481 hp/in
- Run time per tank~6.8 h
Mowing times assume 3.05 acres/hour: deck width x 7.0 mph at 80% efficiency, which allows for overlap, turns and trimming. 7.0 mph is 70% of the 10.0 mph top speed Kubota publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 10.0 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.

What size trailer do I need for the Kubota Z452KWi-54?
At 954 lb, the Kubota Z452KWi-54 on a typical 6x12 open utility trailer (about 900 lb empty) is roughly 1,854 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 1,854 lb. Tongue weight, axle placement and your own trailer's empty weight still have to be checked — this is the arithmetic, not a loading plan.

About 14 min per acre, from its 54-inch deck at 10 mph and 80% efficiency — roughly 4.36 acres an hour, so five acres is about 1 h 9 min. Rough or obstacle-heavy ground takes longer; this is deck width times ground speed, not a timed test.
