Sized for
Lawns of about 1.2 to 1.5 acres (4,860 to 6,070 m²). That is the limit the sizer allows (1.2 times the recommended size) 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 79% pass with room to spare. From there to its 84% rating it is at its limit, and steeper ground rules it out. The methodology states both rules.
