7.7 HYDRAULICS
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).
7.7.1 Reservoir
The mower conditioner's self-contained hydraulic
system uses the APT hitch for the hydraulic oil
reservoir.
7.7.1.1 Oil Level
a. Park mower conditioner on level ground to ensure
top of APT hitch is horizontal. Check oil level daily
(before start-up) when the oil is COLD.
b. If header drive performance improvement system
is installed, proceed to step c. Otherwise proceed
as follows:
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.
1. Check the sight gauge (B) near the middle of
the APT hitch (A).
2. Oil level should be at or near FULL mark on
the gauge (B).
3. To add oil, proceed to Section 7.7.1.2 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.
c. If header drive performance improvement system
is installed:
1. Remove filler cap (C).
2. Oil level should be approximately
3-3/4 to 4-1/8 inches (97–104 mm) below top
surface of filler pipe. Ensure APT hitch is
level.
3. Replace filler cap (C).
4. To add oil, proceed to Section 7.7.1.2 Adding
Hydraulic Oil.
7.7.1.2 Adding Hydraulic Oil
Use single grade trans-hydraulic oil. See Section
7.3.2 Recommended Lubricants.

with the jack.
b. If header drive performance improvement system
is installed, proceed to step c. Otherwise proceed
as follows:
