Scored against the example yard described above. Your yard will differ; the address check below scores your actual lot.
How do I measure my slope?
Slope is rise over run. A 1 ft rise over a 4 ft run is 25%. Yard Truth reads it from USGS lidar elevation when you enter your address.
Does all-wheel drive matter?
Above about 20%, yes. AWD units keep traction when the grass is wet, which is when 2WD mowers slip.
