Hourly income calculation
NOTE
- The harrow hourly income can vary by physical factors such as humidity, slope, soil
hardness, appropriate adjustments and especially the working speed.
To calculate the hourly income, use the following calculation:
R
= L x V x E
X
Where:
R
= Hourly income;
L
= Disk harrow working 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 GNCRP (32 disc blades):
R
= ?
L
= 3.1 m
V
= 7,000 m/h
E
= 0.90
X
=
10,000
m
2
R
= 3.1 x 7,000 x 0.90
10,000
R
: The hourly income working with an equipment that has 32 disc blades will be
approximately of 1.95 hectares per hour.
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.
