Overview
Effective Field Capacity (EFC) measures how much area a machine can cover per hour, accounting for speed, width, and efficiency losses like turns and stops.
💡
Pro Tips
Tillage: Usually has a field efficiency of 70–85% due to higher overlap and draft resistance.
Planting: Usually ranges between 80–90% depending on field shape and seed hopper capacity.
Optimal Capacity: Often, increasing implement width is more effective for capacity than increasing ground speed.
Overlap: GPS guidance systems help maintain closer to 100% efficiency by reducing unnecessary overlap.

Fun Facts
"The '8.25' constant in the formula is a conversion factor derived from (5280 ft/mi) / (43560 sq ft/ac)."
"A 30-foot implement at 5 mph with 80% efficiency covers approximately 14.5 acres every hour."
"Field Efficiency accounts for turns at headlands, stopping to refill/empty, and overlapping past passes."
