4.13 Changing the rotation speed
Fig. 42
The nominal speed is not reached
If the nominal speed of the picker (c. n = 600 U/min)
is not reached, it is possible to correct the rotation
speed by changing the sprocket within the drive (K).
Check whether the starting rotation speed on the
harvester on the drive shaft guard connection in
question (B) corresponds with the works specifica-
tions.
The rotation speed is easy to calculate using the
following formula:
CH rotation speed x upper gear wheel / lower
gear wheel = picker rotation speed
The reduction / increase is performed by changing
one or both of the sprockets The connection chain
may require shortening or lengthening.

Duplex chains
Subject the Duplex chain (C) to regular checks for
the state of the elastic elements (E) and the state of
the drive claw.
Replace worn parts promptly.
