GNACR
Calculation of hourly income
Important data
To calculate the hourly income, use the following calculation:
R
= L x V x E
X
Where:
R
= Hourly income;
L
= Harrow working width, in meters;
V
= Average speed of the tractor, in meters per hour;
E
= Efficiency = 0.90;
X
= Hectare value = 10,000 m
2
.
Example with a GNACR harrow of 64 disc blades:
R
= ?
L
= 6.2 m
V
= 7,000 m/h
E
= 0.90
X =
10,000
m
2
R
= 6.2 x 7,000 x 0.90
10,000
R
: The hourly income working with an equipment of 64 disc blades will be approximately
3.91 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.
The harrow hourly income can vary by physical factors such as humidity,
slope, soil hardness, appropriate adjustments and especially the working
speed.
