7.10 HYDRAULIC DRIVE SYSTEM
The pull-type mower conditioner is hydraulically
powered using the following systems:
• A self-contained hydraulic system to operate
the header functions.
• The tractor remote system to operate the
header lift cylinders, steering, and header tilt
if equipped.
7.10.1 Reservoir
The mower conditioner's self-contained
hydraulic system uses the APT of the machine
for the hydraulic oil reservoir.
7.10.1.1 Oil Level
Check oil level daily (before start-up) at the sight
gauge at rear of APT. Oil level should be at or
near FULL mark on the gauge when top surface
of APT is level and oil is cold.
7.10.1.2 Adding Hydraulic Oil
WARNING
To avoid injury from contact with hot oil, do
not remove cap when system is hot. When
removing cap, unscrew it slowly to vent the
build-up of air pressure in the reservoir.
DANGER
Stop engine and remove key from ignition
before leaving operator's seat for any
reason. A child or even a pet could engage
an idling machine.
a. Level APT by parking on level ground or with the
jack.
b. Slowly unscrew cap (A) from filler tube.
c. Add single grade trans-hydraulic oil until level is
between ADD and FULL marks on gauge. See
