Iowa State University Extension — Farm Machinery Selection (A3-28)
A QUICK WALKTHROUGH
How to use this tool
- Enter the area, effective working width and operating speed.
- Enter your own field efficiency; no recommended percentage is supplied.
- Calculate and copy or download the report.
Formula and units
Capacity (ha/h) = width (m) × speed (km/h) ÷ 10 × efficiency (%) ÷ 100. Hours = area (ha) ÷ capacity (ha/h).
Scope
Width excludes overlap. Field efficiency expresses actual capacity as a share of theoretical capacity, including turning and operational delays. Choose values for your conditions. Results do not predict weather or calendar completion dates.
