Ploughing Time Calculator
Work out how many hours and days it takes to plough, rotavate or cultivate a field of any size.
Time = area ÷ effective field capacity, where capacity (ha/h) = width × speed ÷ 10 × efficiency. A 1.5 m rotavator at 4 km/h and 75% efficiency covers about 1.1 acres/hour — so a 5-acre field takes roughly 4.5 hours, plus travel and setup.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Farmers and custom-hire operators use the free Ploughing Time Calculator for an instant, accurate machinery answer — no formulas to remember, works offline in the field.
About Ploughing Time Calculator
Whether you're booking a hired tractor by the hour, planning to finish sowing before a weather window closes, or quoting custom work, you need a reliable answer to 'how long will this field take?'. This tool turns implement width, speed and a realistic field efficiency into hours and 8-hour days for any field size. It also exposes the per-acre minutes — handy for sanity-checking a custom operator's hour-based bill against the area actually worked.

Frequently asked questions
How long does it take to plough one acre?+
With a typical 2-bottom mouldboard plough (~0.6 m cut) at 4 km/h, about 1.7–2 hours per acre. A 1.5 m rotavator at 4 km/h does an acre in roughly 50–60 minutes. Bigger implements and better efficiency cut this sharply.
Why does the actual time exceed the calculated time?+
Field efficiency below the assumed value: small or irregular fields force constant turning, wet patches slow the pass, and stops for adjustment add up. Re-run the tool with 60–65% efficiency for difficult fields to bracket the estimate.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline at the farm and your data never leaves the device.
