ENERGY REQUIREMENTS FOR TILLAGE ON COASTAL PLAINS SOILS

ABSTRACT Data are presented on the fuel required to perform various tillage operations on different coastal plains soils, for a range of conditions. Unit draft and power requirements for chisel and moldhoard plows were determined for various speeds and plowing depths. Fuel consumption in a no-tillage system and a disc tiller were also measured. Tractive efficiency and fuel consumption were studied as functions of soil characteristics.
