4.9 AUGER ADJUSTMENT
The auger is a very important component in
getting a smooth, high capacity flow of crop
into the feeder house. Factory auger setting is
not intended to be field ready for all types of
crops. The auger must be adjusted for
different crop conditions.
The auger must also rotate freely without
touching the header floor or stripper bars.
Check the minimum factory clearance prior to
operation.
Factory Settings
(Illustration May Not Be Exactly as Shown)
A) Auger Clearance to Header Bottom
For heavy or bulky crops, a clearance of
25mm (1 inch) can increase header capacity.
For a lighter crop, a minimum clearance of
6mm (1/4 inch) will prove to be more
effective.
ATTENTION : If the auger contacts the
header bottom, excessive wear will occur to
auger and header bottom.
The clearance between auger and header
bottom can be adjusted as follows:
Adjust both ends of the auger to maintain a
uniform clearance across the width of the header.
a) Shields can remain in place.
b) Loosen clamp bolts protruding through
rubber stopper and sidewall.
c) Back off the lower auger height adjustment
nuts.
Auger Height Adjustment Nuts
a) Turn the top nuts to raise or lower the auger
on both ends.
b) Turn the auger by hand and check for
clearance along the entire length of the auger.
c) Tighten the lower adjustor nuts.
Clearance between auger and strippers is to be
rechecked after the auger height setting has been
changed. See Auger Clearance to Stripper Bar.
B) Auger Forward/Rearward Adjustment
The auger can be moved forward or rearward to
adjust stripper clearance or improve auger-
feeding performance. The factory settings will
prove very effective in most crop conditions. In
some cases of small grain crops, the auger may
