Characteristics of Multi-
Power Transmission
1. When starting
the
Tractor,
the Multi-
Power Lever
should
be in
''High'' position,
due
to
lubrication of various
components of
the transmission.
2. The
Multi-Power
Lever
may be
shifted without
disengaging
the
clutch,
allow-
ing you
to "shift-on-the-go". When shifting
the
Multi-Power
Lever, always
move the
lever all the way up or down.
3. Disengage the clutch
only when shift-
ing the
gearshift
lever
or dual range lever.
4. The Tractor
should be
operated
in
"High" range
of Multi-Power. This allows
you to
shift
to
''Low'' Multi -Power without
disengaging the clutch when
increased power
is needed.
5. When descending a hill,
shift the
Multi -Power Lever to "High"
for
engine
braking.
6. A Tractor equipped
with Multi-Power
Transmission cannot be
started by pushing or
towing.
7.
If
there
is
difficulty
in shifting
the
standard
gears, move
the Multi-Power
Lever
to ''Low''.
8. Parking procedure:
a. Shut off Tractor engine.
b. SECURELY SET THE MASTER
PARKING
BRAKE.
NOTE:
Multi-Power Transmission
does not permit engine compression
to be used for braking Tractor
parked in gear .
Test for Overload
With the Tractor moving under load, set
the throttle lever half-way open.
Quickly
advance throttle lever to the
"full
open" po-
sition.
The engine should begin to gain
rpm
and build up to its maximum rpm.
If
the
engine fails to gain rpm, it is
overloaded and
you
should shift to a lower gear. Intermit-
tent overload in hilly terrain
operation is
not
harmful.

HYDRAULIC
SYSTEM
(See Figs. 19
and
20)
The
MF
135 Tractors are equipped with
the
world
famous Advanced Ferguson Hy-
draulic System
and 3-Point Hitch, which is,
in brief,
a
combination of mechanical link-
age and hydraulic mechanisms for control-
ling the operation of
implements.
The Advanced
Ferguson
Hydraulic Sys-
tem and 3- Point Hitch, with
Draft
Control,
Position Control, Pressure Control (optional)
and
Response Control, is an easy implement
attachment
system,
capable of
handling
Category
I, 3-point
hitch
implements. This
system
is also equipped with a constant
pumping position, allowing the operation of
remote hydraulic cylinders and Auxiliary
Hydraulic Control Valves (Accessory).
