Sized for
Lawns of about 267 to 333 m² (2,870 to 3,590 sq ft). 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 20% pass with room to spare. From there to its 25% rating it is at its limit, and steeper ground rules it out. The methodology states both rules.
