ABSTRACT THE effects of speed and depth on draft of moldboard plows, chisel plows, disks and sweep plows were investigated on three different Oklahoma soils. Equations similar to those presented in the ASAE Standards were regressed to the data. Draft was found to be a linear function of speed for chisel plows, disks and sweep plows and a quadratic function of speed for the moldboard plows. Draft was directly proportional to depth for all implements.
