3. To maneuver around obstacles in the field:
-- As the unit approaches the obstacle, swing
the header towards the tractor, away from the
obstacle. Be sure to allow enough time for
the machine to pivot and track away from the
obstacle.
-- Straighten out the unit while passing the
obstacle, to avoid running the header more
than necessary into the previously cut crop.
Once past the obstacle, swing the header
fully back into the standing crop.
-- On the next round, steer the tractor around
the obstacle. While steering the tractor,
swing the header towards the tractor to keep
it following the cut line as long as possible.
Center the unit behind the tractor while
passing the obstacle. As the tractor exits the
uncut crop, gradually steer the header away
from the tractor to keep it in the standing
crop.
4. To cut oversquare corners:
-- While approaching a sharply angled corner,
gradually swing the header towards the
tractor, to keep the unit positioned between
the previously cut windrows. As the header
comes out of the standing crop, raise the
header and turn the tractor to the right;
continue to swing the unit towards the left, as
this will move the tongue away from the
tractor tire to allow sharper turning.
-- When the turn is nearly completed, swing the
header away from the tractor so that it is
aligned with the standing crop, and centered
between the previously cut windrows. Lower
the header into the crop, and gradually swing
the header fully into the standing crop.
NOTE: Maintain full PTO speed when crossing
previously cut windrows, even if the header is fully
raised. Failure to do so may cause cutter bar and/or
conditioner roll plugging.
