Sized for
Lawns of about 4.12 to 5.15 acres (16,670 to 20,830 m²). That is its rating divided by 1.5 for a complex lawn and by 1.2 for an open one, the margins the mower sizer adds for the shape of the lawn.
Slopes up to 65% pass with room to spare. From there to its 70% rating it is at its limit, and steeper ground rules it out. The methodology states both rules.
