hectare per hour

Area per timeexact by definition

The hectare per hour is the metric measure of field capacity — how fast a machine actually covers ground, allowing for overlap, turning and stops. Exactly 10⁴ ÷ 3600 m²/s, about 2.778.

About the hectare per hour

Field capacity is the number that turns a machine into a schedule, and it has a tidy metric shortcut:

ha/h = width (m) × speed (km/h) × efficiency ÷ 10

A 6-metre drill at 8 km/h with 80% field efficiency covers 6 × 8 × 0.8 ÷ 10 = 3.84 ha/h. A 100-hectare seeding job is therefore 26 hours in the seat, which is the figure that decides whether the crop goes in during the weather window.

Field efficiency is where optimism dies. Theoretical capacity assumes the machine never turns, never fills and never stops; real efficiency runs 70–85% for tillage and seeding, and can fall below 60% for a combine in a small, awkward field.
