Adjusting the threshing drum speed
DOMINATOR 130
– Unblock the threshing drum gate (7 / 8) with
lock (Y).
Reducing the threshing drum speed
– Move lever (1) from the neutral position (N)
towards (7), thus reducing the threshing drum
speed.
Increasing the threshing drum speed
– Move lever (1) from the neutral position (N)
towards (8), thus increasing the threshing drum
speed.
Blocking the threshing drum gate
– Block threshing drum gate (7 / 8) with lock (Y).
Consequently, the drum speed cannot be acciden-
tally changed.

11.6.7 Threshing drum two-step variable-
speed drive (chain drive)
– Observe the general warnings at the beginning of
the "Fieldwork" chapter.
An optional chain drive kit for threshing crops that
crack easily can be installed in place of the drum varia-
ble-speed drive.
Three speeds can be obtained by changing sprockets
(2). An additional fourth speed can be obtained by
replacing sprocket (1) on the impeller shaft.
For a speed of 550 rpm, the standard length of chain is
72 rollers.
