  SECTION 6 OPERATION 
169000  88  Revision F 
6.17.14 Forming Shields 
WARNING 
Keep hands and feet away from discharge 
opening. Keep everyone several hundred 
feet away from your operation. Never direct 
the discharge toward anyone. Stones or 
other foreign objects can be ejected  
with force. 
Position of forming shields controls the width 
and placement of the windrow. The decision on 
forming shield position (settings between 36 in. 
and 92 in. [915 and 2346 mm]) should be made 
based on the following factors: 
•  weather conditions (rain, sun, humidity,  
and wind), 
•  type and yield of crop, 
•  drying time available, and 
• method of processing (green-feed,  
bales, silage). 
A wider windrow will generally dry faster and 
more evenly, resulting in less protein loss. Fast 
drying is especially important in areas where the 
weather allows only a few days to cut and bale. 
Refer to Section 6.18 HAYING TIPS for  
more information. 
Where weather conditions permit, or when 
drying is not critical, for example, when cutting 
for silage or green-feed, a narrower windrow 
may be preferred for ease of pick-up. 
6.17.14.1 Side Deflectors 
The position of the side forming shields controls 
the width and placement of the windrow. 
CAUTION 
To prevent accidental movement of 
windrower, place all controls in NEUTRAL or 
in PARK, engage park brake (if applicable), 
shut off engine, and remove key. 
To ensure windrow placement is centered with 
respect to carrier/drive wheels, adjust both side 
deflectors to the same hole position on the 
adjuster bar. 
To achieve this setting, adjuster bars must be in 
the corresponding hole both sides. 
a.  Set forming shield side deflectors to desired 
width by repositioning adjuster bars as follows: 
1.  For self-propelled machines, remove 
lynch pin (A), move adjuster bar (B) to 
another hole, and reinstall lynch pin (A). 
2.  For pull-type machines, remove hairpin 
and clevis pin (C). Move adjuster bar (D) to 
another hole, and reinstall clevis pin (C)  
and hairpin. 
b. If forming shield attachment is too tight or too 
loose, adjust as follows: 
1.  On self-propelled headers, tighten or 
loosen nut (E) as required. 
2.  On pull-type headers, back off top nut  
at (F), and adjust lower nut at (F) as 
required. Then, holding lower nut with a 
wrench, tighten top nut securely against 
lower nut.
