Calculation of hourly income
NOTE
Based on this calculation, the table on the following page shows the average hourly
income and also for a day, that is, nine (9) hours of work.
To calculate the hourly income, use the following calculation:
R
=
L x V x E
X
Where:
R
= Hourly income;
L
= Harrow cutting width (meters);
V
= Average speed of the tractor (meters per hour);
E
= Efficiency: 0.90;
X
= Hectare value = 10,000 m
2
.
Example with a GAPCR (16 disc blades):
R
= ?
L
= 2.55 m
V
= 6,000 m/h
E
= 0.90
X =
10,000
m
2
R
= 2.55 x 6,000 x 0.90
10,000
R
= 1.38 hectares per hour.
Important data
The harrow hourly income can vary by physical factors such as humidity, slope,
soil hardness, appropriate adjustments and especially the working speed.
