11 Fieldwork 11.6 Threshing mechanism 67087 Adjusting the threshing drum speed DOMINATOR 130 H 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. 7 8 Y Increasing the threshing drum speed Move lever (1) from the neutral position (N) towards (8), thus increasing the threshing drum speed. DOMINATOR 130 19409 34 Blocking the threshing drum gate Block threshing drum gate (7 / 8) with lock (Y). Consequently, the drum speed cannot be acciden- tally changed.
55569 11.6.7 Threshing drum two-step variable- speed drive (chain drive) Observe the general warnings at the beginning of the "Fieldwork" chapter. 3 1 An optional chain drive kit for threshing crops that crack easily can be installed in place of the drum varia- ble-speed drive. 4 Three speeds can be obtained by changing sprockets (2). An additional fourth speed can be obtained by replacing sprocket (1) on the impeller shaft. 2 35 19611 For a speed of 550 rpm, the standard length of chain is 72 rollers. 212 00 0293 210 2 - BA DOMINATOR 150/140/130 - 12/09 Sprocket Teeth Speed of 1 17 300 rpm 2 64 1 17 430 rpm 2 45 1 17 550 rpm 2 35 Additional stage: 1 15 265 rpm 2 64
