The harrow hourly income can vary by physical factors such as humidity, slope,
soil hardness, appropriate adjustments and especially the working speed.

E
Where:
A

.
Example with GCRO 7010 of 32 discs:
A
= ?
B
= 4.19 m
C
= 6,000 m/h (6.0 km/h)
D
= 0.90
E =
10,000

A
= 4.19 m x 6,000 x 0.90
10,000
A = 2.26 hectares per hour.
