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.
