ABSTRACT Tillage drafts and fuel measurements were made for 12 soil series and major implements used in North Carolina crop production systems. Implements included moldboard plows, chisel plows, offset and tandem disks, planters, ridger-disk bedders, ridger-planter and subsoiler. An 81 kW tractor instrumented with a personal computer and a data interface measured ground speed, fuel consumption and implement draft. Draft measurements were compared to those predicted by ASAE Machinery Management Data and were found to vary. Measured fuel consumptions for conventional tillage systems ranged from 25.96 to 40.39 L/ha while minimum tillage systems ranged from 20.88 to 28.36 L/ha.
