Cutterbar Crop Stream Configuration - MacDon R113 Operator's Manual

4.5.3 Cutterbar Crop Stream Configuration

Discs are factory-installed to produce three crop streams, but disc rotation pattern can be changed by substitution
of spindle and corresponding disc to suit crop conditions. Each spindle and disc pair is designed to rotate in one
direction and must be changed as sets when altering crop flows.
Reducing or increasing the number of crop streams will
produce the following results:
•
Reducing the number of crop streams will result in
narrower windrows.
•
Increasing the number of crop streams will result in
smoother, wider windrows.
NOTE:
Increasing the number of crop streams will also increase
the number of diverging disc pairs which may negatively
affect cut quality in certain conditions.
IMPORTANT:
•
Spindles that rotate clockwise have right-leading
threading and a smooth top on the spindle gear
shaft (A).
•
Spindles that rotate counterclockwise have left-
leading threading and machined grooves on the
spindle gear shaft (B) and nut (C).
•
If spindle position in cutterbar has changed, the
rotational direction of that spindle MUST remain the
same (i.e., a clockwise spindle must maintain its
clockwise rotation).
•
Failure to maintain rotation pattern can result in
damage to spindle and/or cutterbar components.
