6.3 Determining the seeding shaft speed
To spread the desired seed rate, read the required seeding shaft speed [%] from the seeding tables
(as of page 107).
Example:
Seed: ....................................................... Rapeseed
Desired spread rate: ......................................... 20.2 [kg/ha] = 1.62 [kg/min.]
Forward speed:................................................. 12.0 [km/h]
Working width: .................................................... 4.0 [m]
Seeding shaft with seed metering wheels: . fb-f-fb-fb
Seeding shaft speed: .................................. 50 [%]
Conversion of the spread rate from [kg/ha] to [kg/min]
The desired spread rate [kg/min] is specified in the seeding table. The following formula is used to
convert the spread rate in [kg/ha] to spread rate in [kg/min.]. The inserted values come from our ex-
ample (see above).
spread rate [kg/min.] =
spread rate [kg/ha] x tractor speed [km/h] x working width [m]
600
Spread rate [kg/min.] =
20.2 [kg/ha] x 12.0 [km/h] x 4.0 [m]
= 1.62 [kg/min.]
600
