BALING STRAW
Guidelines for Optimizing Straw
Quality
Due to the threshing and separating nature of the
AXIAL-FLOW® Combine, machine settings and
operating conditions can affect the quality of baling
straw. The following guidelines are to help you obtain
the best straw possible from your AXIAL-FLOW®
Combine. Each field condition must be looked at in
particular to identify which options will give view
satisfactory results.
Recommended Equipment Options
AFX Rotor
- Remove the straight separator bars and install rasp
bars.
- Do not use spiked rasp bars, except in Damp,
weedy conditions.
Other Equipment
- Use small wire concaves or at least one at the No. 1
position.
- Use slotted grates with the channels on the outside
in the 1/2 hole position.
- Solid separator grates in the Nos. 2 and 3 positions
may be used if grain l loss is not an issue.
- If possible, use a machine equipped with a
discharge beater instead of a straw chopper.
Operating Conditions
- Harvest during damp, tough conditions such as
early morning or late evening.
- Cut more of the stem than usual.
- Remove the spreaders or, if impacting in stubble is
a problem, leave the spreader discs attached and
remove the bats and/or angles.
Machine Settings
- Use slower than normal rotor speeds.
- Relax the concave setting while maintaining
threshing and separating.
- Lower chopper, beater pan to the CORN position.
- Adjust the vanes over the grates to the fast or
forward position.
- Adjust the vanes over the concaves in the mid to
fast position.
- Retract the straw chopper concave and/or slow
speed of chopper/beater.
- Use a slower speed on the rock trap beater (if
equipped).
NOTE: Care should be exercised to avoid
compromising acceptable grain loss and machine
performance.
