Brakes while driving
and harvesting (fig. 12)
The harvester has negative hydraulic Oil
Immersed Multi Disc Brakes. Braking power
is generated by springs, and the brakes are
released using hydraulics. Each wheel hub
has its own brake. With the gear engaged, the
hydrostatic drive transmission always brakes
itself when the drive pedal goes toward its
mid-position.
The brakes are mainly controlled from the cab
using a triple-position switch (fig. 2, switch
C). Using the triple-position brake switch, the
brakes can be engaged, disengaged and put in
their automatic position hydraulically. In their
mid-position the brakes are always engaged,
and when depressed all the way back they
are always disengaged. In their forward posi-
tion, that is the automatic position, the brakes
operate depending on the position of the drive
pedal. When harvesting or driving on hilly
roads, the brake switch should be in its auto-
matic position.
In the cab there is also brake pedal A, which
can be depressed to generate braking power
on the brake shoes comparable to pedal power.
The brake pedal is mainly intended for use on
the road to meet the road traffic regulations.
Parking brake
The parking brake gets engaged automatically when the engine is switched off. Multi-disc brakes
operates as parking and working brakes.
Frame lock
The frame lock operates similarly to the brakes. Depending on the position of the frame lock
switch, the dual-function cylinders either locks the frames together, allows them to turn indepen-
dent of each other or operates in the automatic position at the same time with the brakes. With
the frame lock switch (fig. 2, switch C) in its mid-position, the frame lock is always engaged and
when depressed backward, the frame lock is disengaged. Normally when harvesting, the frame
lock switch should be in its automatic, that is in its forward position.
