OPERATION
"GRASS SEED SPECIAL" HEADER
The grass seed auger header has several features
to adapt it to this special application. These
features include:
Stub Guards and Hold-downs: The cutterbar is
equipped with stub guards for effective cutting in
tough grass crops. See "Sickle and Sickle Drive"
in Maintenance/Service section for maintenance of
these components.
Special Auger Design: The center beaters and
beater supports have been removed to reduce
auger wrapping.
Slower Auger Speed: For 12’ & 14’ Headers, the
slower auger speed of 170 RPM (compared with
205 RPM for 16’ and standard header) also
reduces auger wrapping.
Adjustable Stripper Bars: The two upper sets of
stripper bars are adjustable for more effective
stripping of grass crops.
To adjust:
1. Loosen bolts (G) along upper stripper bars.
2. Slide extension bars (H) in or out to obtain
approximately 1/8 inch (3 mm) clearance to
auger flighting (J) along entire auger length.
3. Tighten bolts (G).
Auger Pan Extensions: One pan extension is
provided to reduce delivery opening from the
maximum 68 inches (1720 mm) to 59 inches (1490
mm). A second pan extension may be ordered to
further reduce opening to 50 inches (1260 mm).
NOTE: When installing auger pan extensions (A):
1. The pan supplied is factory assembled to be
installed on the left side of the delivery
opening, with cutterbar support (D) at inboard
side. Install hardware supplied as shown.
2. Move the two upper sets of stripper bars (B)
so end of stripper is flush with edge of pan
extension. The lowest (most forward) set of
stripper bars (C) should remain in standard
pan position as shown. Reset upper stripper
bars clearance as described above.
Windrow Forming Rods: Forming rods are
provided to assist in forming the narrow windrows
preferred for this application. Bend the rods to
modify the windrow shape. Use the forming rods in
conjunction with the auger pan extensions to
achieve the width and shape of windrows you
desire. See “forming rod installation” section.
Six-Bat Reel: A sixth bat is added to the reel body,
for smoother reel action and better crop feed into
the header.
