6.6 BREAK-IN PERIOD
a. After attaching mower conditioner to tractor for
the first time, operate the machine slowly for
5 minutes, watching and listening FROM THE
TRACTOR SEAT for binding or interfering parts.
NOTE
Until you become familiar with the sound
and feel of your new mower conditioner,
be extra alert and attentive.
CAUTION
Before investigating an unusual sound or
attempting to correct a problem, shut off
tractor, engage parking brake, and remove
key.
b. Perform the items specified in to Section 7.4.2
Break-In Inspections.
6.7 ENGAGING THE PTO
DANGER
Be sure all bystanders are clear of the
machine before engaging the PTO. Never
leave tractor seat with the PTO engaged.
a. Engage the PTO slowly, just before the mower
conditioner is moved up to the standing crop.
b. Be sure tractor PTO is running at 1000 rpm
before starting to cut.
c. Disengage the PTO when not operating the
mower conditioner.
d. To prevent pump cavitation, run machine at low
tractor idle for approximately 10 minutes when
ambient temperature is 50°F (10°C) or less.
6.8 RAISING AND LOWERING HEADER
The header raise/lower control is not normally
used to control cutting height since cutting is
usually performed with the cutterbar on the
ground.
This control is used to raise the header to clear
obstacles and windrows during field operation,
to adjust the header height for maintenance, and
to raise the header for transport behind a tractor,
or for storage.
DANGER
Be sure all bystanders are clear of the
machine before raising or lowering header.
a. Raise or lower header by activating cylinder
control lever (A) in tractor.
IMPORTANT
Hoses should be connected so that
moving control lever (A) backward raises
the header. See Section 6.4.3 Hydraulic
Connections for more information.
