Water infiltration rates into soils can provide important insights into the physical properties of the soil and its potential for crop production. Rainfall infiltrometers can make measurements under conditions closer to natural rainfall than ponded or tension infiltrometers. In the past, field measurements of infiltration with rainfall simulators have required the transport and assembly of bulky equipment. A self-contained rainfall infiltrometer was designed and constructed on a high-clearance tricycle tractor that can be easily transported over roads on a trailer and then driven in cropped or uncropped field plots. Performance of the unit is the same as the trailer-based infiltrometer that it replaced.
