What the specs work out to
Figures MowerFacts computes from Altoz’s own numbers — not published by the manufacturer.
Mowing time
- ¼ acre4 min 3 min
- ½ acre7 min 5 min
- 1 acre15 min 10 min
- 2 acres29 min 20 min
- 5 acres1 h 13 min 51 min
- 10 acres2 h 26 min 1 h 42 min
About 15 min per acre at 4.11 acres/hour, mowing at 7.7 mph. The second figure is at the published 11.0 mph top speed (5.87 acres/hour) — faster than anyone really mows. About 57.5 acres per tank.
Gate & trailer fit
- 32 in gateToo wide
- 36 in gateToo wide
- 48 in gateToo wide
Needs at least 72 in of clearance (estimated).
Power & run time
- Power per deck inch0.583 hp/in
- Run time per tank~14.0 h
Mowing times assume 4.11 acres/hour: deck width x 7.7 mph at 80% efficiency, which allows for overlap, turns and trimming. 7.7 mph is 70% of the 11.0 mph top speed Altoz publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 11.0 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.
Run time assumes a typical 1 gal/hour burn at working load; real consumption varies with engine, load and cut.
