11 Fieldwork 11.10 Grain delivery 67087 11.10 Grain delivery 83011 11.10.1 Inspecting the returns Coarse particles (e.g. unthreshed heads) drop through the upper sieve and from the lower sieve into the returns auger which moves the material to the returns elevator. The elevator carries the returns to the thresh- ing drum for second threshing. Excessive returns cut down on efficiency and cause cracked grain and grain losses. Excessive returns can have a number of reasons: Incorrect setting of the threshing mechanism, con- cave, threshing drum speed (excessive cracked grain). Sieves set too close or lower sieve holes too small. Incorrect setting of the wind blast (too high or too low).
Ground speed too high. Engage the threshing mechanism. Set the diesel engine speed to fast idling speed. Move the machine into the crop. 72 19644 2 Danger! 1 Rotating and moving machine parts. 3 Death or serious injuries! Keep a sufficient distance from all rotating and moving machine parts. 19646 73 Actuate lever (3) and open cover (2). Inspect the quantity and composition of the returns (1) by means of a visual inspection. If necessary, correct the machine setting. 83021 11.10.2 Opening / closing the grain tank cover Danger!
