Estimate mowing time from measured area, cutting width, speed, overlap and turning efficiency.
How this calculator works
Effective width = full cutting width × (1 − overlap ÷ 100). Productivity = effective width in metres × actual speed in metres/hour × turning efficiency ÷ 100. Mowing minutes = area ÷ productivity × 60. Overlap is applied separately: do not also include the same overlap loss in turning efficiency. Additional minutes cover work outside mowing. The demonstration values are editable assumptions, not manufacturer performance guarantees. Slopes, obstacles, wet grass and bag emptying can increase time. Use an appropriate speed for your equipment and conditions.
Units and inputs
Use measured inputs and replace the demonstration values. 1 ft = 0.3048 m; 1 sq ft = 0.09290304 m²; 1 inch = 25.4 mm; 1 US gallon = 3.785411784 litres. All entered prices must use the same currency. Zero prices omit the optional budget.
