Energy requirements for a land imprinter and rangeland drill, were determined on seedbeds with -6.5, 0.0, 5.0, and 8.5% slopes. The imprinter was tested empty (1.3 Mg/m), full (1.9 Mg/m), and half-full (1.67 Mg/m) of water. The rangeland drill was half width (1.5 m wide). Each implement was pulled over 4 replicated 23-m runs per slope. During each test run we recorded speed of travel and 10 drawbar force measurements, sensed with a load cell and integrated over 100 milliseconds. A procedure outlined by the American Society of Agricultural Engineers was used to estimate cost of use for a 3-m wide rangeland drill and imprinter 3/4 full of water. A 5-year implement age and 100 hours use per year were assumed. Operating costs for the land imprinter and rangeland drill were $56.92/ha and $40.27/ha, respectively, excluding grass seed.
