Adjusting of the CUTTING TABLE ANGLE in
Soft Conditions:
Remove the cutting table.
Remove the
¿ ller beam from the
joint between the feed elevator and the lower end of the
table,
¿ g. P21.
This adjustment may be necessary in such soft harvest-
ing conditions in which the front tyres of the combine
sink so deep into the soil that the position of the knife in
relation to the ground changes. By adjusting the position
of the table, the original position can be restored.

Periodically, preferably at the beginning of each harvest-
ing season, check the position of the concave in relation
to the threshing cylinder, i.e. the cylinder
concave clear-
ance. Use tool R152308.
‡ First adjust the concave adjustment indicator to posi-
tion 20 and then further up to 12.
‡ Now the clearance, i.e. the feed distance between
the
¿ rst concave rasp bar and a cylinder rasp bar,
should be 12 mm.
‡ Correspondingly, the clearance between the last
concave rasp bar and a cylinder rasp bar shall be 6
mm.
‡ If there is deviation, adjust the clearance using nuts
B at the lower end of the concave adjusting arm A,
¿ g. P22.
‡ Check the measurements from all four corners of the
concave.
