CHAPTER V
PLANTER WORKING CAPACITY
FORMULA TO CALCULATE WORKING CAPACITY
Qty (hect./h) = Ww(m) x Sp(km/h) x Cx0,1
References:
Qty:
It’s the planted surface calculated in hectares per hour.
Ww: Effective working width of machine calculated in meters (number of rows x row spacing in meters).
Sp: It’s the effective working speed calculated in kilometers / hour.
C: It’s the coefficient of time loss per turnings in corners and seed and /or fertilizer loads.
0,1: Constant numerical value equal to the result in hectares per hour (hect./h), when the effective working width units
(Ww) are expressed in meters (m) and the speed in kilometers/hour (Km/h).
If effective speed (Sp) is not indicated on tractor, it can be obtained by considering the time the machine takes in running
a certain distance.
Example:
Running distance: 100 meters
Time invested in running that distance: 50 seconds
The coefficient (C) of time loss depends on the working
system.
If 15% time loss is assumed, the coefficient (C) results in
a numerical value of 0,85.
Sp =
100 x 3,6 = 7,2 km/h

Example of working capacity calculation:
For a TD 21 module (24 rows at 21 cm spacing)
Ww: 5,04 meters
Sp: 7,2 Km/h
C. 0,85
This means that you will be able to seed 3,08 hectares in
an hour at that speed (7,2km/h) considering that time loss
(15%).
If speed or delays in turnings and seed/fertilizer loads
vary, effective working capacity will vary, too.
Qty= 5,04m x 7,2Km/h x 0,85 x 0,1
Qty = 3,08 hect./h
