7.5.3 Fan speeds
The required fan speed depends on the fertiliser quantity.
Travel speed, weight and shape of fertiliser in form of granules or powder and other
factors also have an influence on the required air quantity.
The table values therefore only serve as guide values. The rotational speed actually
required may differ from the specification.

Table 1: Reference values of fan speeds at 10 km/h
NOTE
The optimal rotational speed must be determined by field tests or during a test
placement.
The guide values must only be fallen short of if the correct distribution at a lower
speed was determined during measurement of the transverse distribution.
Fan speed too low With a too low fan speed
• fertiliser may remain in the hoses and cause blockage.
• the distribution can be negatively influenced.
1. Increase the fan speed. Make sure that no seeds are placed outside the fur-
row.
2. Reduce the travel speed, because the maximum fertiliser quantity may be
reached.
NOTE
Ø
The rotary speed settings must be checked once again with the oil warmed
up.
