Reconfiguring Cutterbar Crop Stream
Discs are factory-installed to produce four 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.
Figure 3.56: R216 Cutterbar
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.
Figure 3.57: Cutterbar Spindles
IMPORTANT:
•
Spindles that rotate clockwise have right-leading threading
and are identified by a smooth top on the spindle gear
shaft (A).
•
Spindles that rotate counterclockwise have left-leading
threading and are identified by 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 (that is, a
clockwise spindle must maintain its clockwise rotation).
•
Failure to maintain rotation pattern can result in damage to
spindle and/or cutterbar components.
•
Safecut (shear pin) will not work if spindles used in the
wrong orientation.
