MASSEY FERGUSON MF 135 - Hydraulic System

Dperating 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).
