CUTTING
IMPORTANT: Do not engage the PTO with the
engine running at high speed or the pump drive can
be damaged.
Slowly engage the PTO before the unit is moved up
to the standing material. Be sure the tractor PTO is
running at the standard RPM (540 to 1000) before
starting to cut.
IMPORTANT: Operating at excessive PTO speeds
can shorten machine life and cause structural failure.
A ground speed of 6 km/hr-8 km/hr (4 MPH-5 MPH)
is satisfactory for many crop and field conditions.
Higher speeds may sometimes be used when
operating in a light crop. PTO speed must be
maintained regardless of ground speed. When
conditions make it necessary to slow ground speed,
shift to a lower gear rather than reduce engine speed.
The first swath can be cut with the header on either
side of the tractor. Cut the back swath in the opposite
direction to pick up more of the crop that was run
down by the tractor tires. Cut the back swath at a
slower speed to pick up most of the crop.
1. To cut square corners:
-- Start turning the tractor after the rear wheels
pass the edge of the standing crop. At this
time, swing the header toward the tractor,
using the swing cylinder control lever and at
a rate required to maintain straight line travel
of the header to the end of cut.
Do not raise the header.
-- When the turn is nearly completed, swing the
header away from the tractor.
-- With practice, corners can be cut without
leaving standing crop.
2. To cut back and forth:
-- First cut three or four swaths around the field
to open the field. Then cut back and forth on
one side of the field. Raise the header after
each swath and shift the header to the other
side of the tractor while turning. With
practice, the header can be shifted to the
opposite side of the tractor in steps, during
the turn, to make a short radius turn without
missing standing crop.
