MAN0943 (07/12/2011)
1. Leave standard flails located between the rows.
2. Remove others and install shorter flails to follow
ground contour. Be sure to mount the same size
flails on opposite sides of the tube. Measure the
row spacing and flail position carefully to minimize
ground contact. See page 36 and page 37.

Setting Flail Height
1. Be sure wheels are set to follow in the center of
furrow row. Set flails 3 to 6 inches (75 to 150
mm) above the ground. (See Balance Statement,
page 5.)
2. Align the unit with the working area on or between
rows on flat farming.
3. Use stroke control spacers on four cylinders to set
cutting height.
Figure 12. Setting Flail Height
Setting Caster Wheels
Normally, wheels are set to track in the row centers,
between the raised seed beds. Tire position will deter-
mine flail height, but depth of furrow is also a factor in
setting flail height. In some conditions the furrow
between the seed beds is deeper on the ends, where
irrigation waters enter the field. As furrows change
depth, flail height will change.
To compensate for the depth change, move the caster
wheels against the side of the outer seed bed (see Fig-
ure 13). The wheels will then tend to climb up the side
of the seed bed and prevent the flails from hitting the
top of the bed.
Set the flail height after the wheels have been moved
against the seed bed.
