Enter the working width, speed, and field efficiency to find out how many hectares the machine covers per hour and per day.
Pre-sizing and estimating tool: the results do not replace a design, calculation, or report signed by a qualified professional, nor verification against the applicable standards.
How many hectares per hour the machine covers at each speed, with the width and efficiency you entered; the dot marks your operation.
Daily output with the effective hours you entered; the highlighted bar is your efficiency.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Output in hectares per hour for combinations of working width and speed, with the field efficiency you entered.
The calculation done in steps, with the values you entered.
The calculation memo gathers this page's inputs, results, equations, assumptions, and references, with fields for project, responsible person, and review. The full report also includes the charts and interpretations, in color. In the print window, choose Save as PDF.
Enter the implement's working width, average speed, field efficiency, and effective hours per day. The calculator returns the theoretical and effective capacity in hectares per hour, the daily output, and the days needed for the area.
Boom sprayer of 6 m at 8 km/h, 75% efficiency, 10 effective hours per day and an area of 100 ha.
Theoretical = 6 × 8 ÷ 10 = 4.8 ha/h. Effective = 4.8 × 0.75 = 3.6 ha/h. Per day = 3.6 × 10 = 36 ha. For 100 ha, about 2.8 days.
To convert yield into cost per hectare, use the machine hourly cost; for plot planning, see passes, time and diesel.
It is the ratio between the time actually worked and the total time of the operation. Turns, refueling, adjustments and stops reduce efficiency.
Width usually gives more return, because it increases the area per pass without affecting quality. Speed is limited by coverage and by the equipment's settings.
Time the area worked in one full hour, counting the stops. Divide the area by the effective time and compare with the theoretical value.
Divide the machine's hourly cost by the effective capacity in ha/h. The result is the cost per hectare of the operation.
Important notice: the Agrocalcs tools make estimates and preliminary sizing based on the data entered and on published engineering methods. They do not replace a design, a calculation report or a report signed by a qualified professional (CREA/ART), nor verification against the applicable technical standards and legislation, such as the Regulatory Standards of the Ministry of Labor. Material and fuel properties vary: check with the manufacturer or with analyses of your process before deciding. By using the site, you agree to the Terms of Use.
