OPERATION
HEADER FLOTAnON
Header flotation springs
are
normally

Ibs.
force
(311
N) is required to
lift
either end of
the header
just off
the
ground.
In
rough
or stony conditions,
it
may
bl~
desirable
to
change setting
to
35-50
Ibs.
(156-222
N) to
protect
cuning
components.
NOTE:
When float
setting Is Ught, It ma.y be
necessary to use
a
slower
ground speed
to
avoid excessive
bouncing and
leaving
a
ragged
cut.
To
Increase
header
f1otatron,
which
decreases
the force required to lift
header:
a.
Raise
header
fully.
b.
Back
jam
nut
(A)
away
from
spring.
c.
Turn
adjuster
bolt
(8)
further into
spring
to increase
flotation.
d.
Tighten
jam
nut
(A) against spring Insert (C)
to
secure
the
setting.
e.
lower header and
check
header
f1o~ation
at
each end.
IMPORTANT:
Float
setting
(or lifting force) must be
equal
on both
springs.
Weight
difference between
left
and
right ends requires
different spring
lengths to
achieve equal
float
at
both
ends.
Note that
other operating
variable adjustments
may affect float
sEltting.
Check the float and
readjust
if
necessary
after
adjusting reel
position, cutting
height,
or
c
utterbar
angle. Also,
if using
a
tractor
with drawbar
height
different than
16
Inches (406
mm) flotation
will
be
affectl~.
Adjust as
required
