Enter the field, the working width, and the speed to find out how many passes to make, how long it takes, and how much diesel it uses.
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.
Total time for the plot at each speed, with the width and turns you entered; the dot marks your speed.
Total time for the same plot at different widths; the highlighted bar is yours.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Hours for the field across combinations of speed and working width, with the row length and turn 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 field area, the length of the working row, and the implement width. Then type the average speed, the turn time at each pass, and the diesel consumption of the operation. The calculator returns the number of passes, the total time, and the diesel used.
Field plot of 50 ha, rows 800 m long, 6 m implement at 8 km/h, 30 s turning time and fuel use of 14 L/h.
Passes = 500,000 ÷ (800 × 6) = 104.2, rounded to 105 passes. Time per pass = 800 ÷ 2.22 + 30 = 390 s. Total = 105 × 390 ÷ 3,600 = 11.4 h, with about 160 L of diesel.
Longer rows reduce turns and increase output. The ideal length depends on the field's shape, topography, and slope, and should not go past the point where the contour line or the terrain forces a change of direction.
To add diesel to the operation cost, use the machine hourly cost, and for the machine capacity, see the operational capacity.
Divide the area in square meters by the product of the row length and working width. Always round up, because the last pass counts in full.
Because every pass includes a turn. On short rows, turns can take more time than the work itself; that is why long rows increase output.
Yes. In general, hourly consumption rises with load and speed. Use the value measured in similar operations, not the catalog figure at maximum load.
Use it to estimate the diesel for an operation. For total cost, add depreciation, repairs, labor and the other costs from the hourly cost.
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.
