Work out field capacity of machine instantly with clear inputs, formula shown and shareable results.
Theoretical field capacity in hectares per hour is width (m) x speed (km/h) / 10. Real output is lower because of turning, overlap, filling, adjustment and unloading, captured by field efficiency — around 70-85% for tillage, 60-75% for planting and 65-80% for combining.
Field capacity
Theoretical (ha/h) = width (m) x speed (km/h) / 10; effective = theoretical x field efficiency
Time
Hours = area / effective field capacity
Width in metres times speed in km/h gives 1000 m2 per hour per metre-km, and 10,000 m2 make a hectare, so the constant collapses to 10.
Widening the implement helps most, then reducing turning time with longer runs and headland planning. Raising speed helps only until work quality or safety suffers.
