Field Capacity Of Machine Calculator

Work out field capacity of machine instantly with clear inputs, formula shown and shareable results.

About Field Capacity Of Machine Calculator

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.

Formulas

Field capacity

Theoretical (ha/h) = width (m) x speed (km/h) / 10; effective = theoretical x field efficiency

Time

Hours = area / effective field capacity

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why the divide-by-ten?

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.

How can I raise field capacity?

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.
