What the specs work out to
Figures MowerFacts computes from Altoz’s own numbers — not published by the manufacturer.
Mowing time
- ¼ acre7 min 5 min
- ½ acre14 min 10 min
- 1 acre28 min 19 min
- 2 acres55 min 39 min
- 5 acres2 h 18 min 1 h 37 min
- 10 acres4 h 36 min 3 h 13 min
About 28 min per acre at 2.17 acres/hour, mowing at 5.6 mph. The second figure is at the published 8.0 mph top speed (3.1 acres/hour) — faster than anyone really mows. About 10.8 acres per tank.
Weight & hauling

- Towed weight1,700 lb
- single-axle 3,500 lbCarries it, 1,800 lb spare
- 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

- 36 in gateToo wide
- 48 in gateToo wide
Needs at least 54 in of clearance (estimated).
Power & run time
- Power per deck inch0.479 hp/in
- Run time per tank~5.0 h
Mowing times assume 2.17 acres/hour: deck width x 5.6 mph at 80% efficiency, which allows for overlap, turns and trimming. 5.6 mph is 70% of the 8.0 mph top speed Altoz publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 8.0 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because Altoz 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 Altoz'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 Altoz XR 480 / 540 / 540 SS?
At 800 lb, the Altoz XR 480 / 540 / 540 SS on a typical 6x12 open utility trailer (about 900 lb empty) is roughly 1,700 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 1,700 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.
How fast is the Altoz XR 480 / 540 / 540 SS?

About 19 min per acre, from its 48-inch deck at 8 mph and 80% efficiency — roughly 3.1 acres an hour, so five acres is about 1 h 37 min. Rough or obstacle-heavy ground takes longer; this is deck width times ground speed, not a timed test.
