USE OF CLUTCHES
The
tractor
has two clutches.
The first
clutch
connects the engine to the P.T.O.; disengage by actuating
lever
14
(fig. 12).
The second clutch connects the engine to the gearbox; disengage by depress-
ing pedal
11
(fig. 12).
USE OF BRAKES
Each rear wheel brake is separately controlled
by
its own pedal (right pedal
for
the
right
wheel and left pedal for the left wheel). Braking with one pedal is
useful when the tractor must perform a sharper turn; by locking the wheel
on
inner side of turn the
tractor
will pivot on the braked wheel.
When traveling on road, interlock the pedals with their inter-locking latch.
To
lock
the brakes, depress both pedals and pull the lever up. To release the
brakes step on pedals, thumb the button lever grip and push the lever downward.
Is
the
tractor
provided with
an
independent hand brake, apply the brakes on
the power train, after the tractor has stopped, by moving handlever 1
upward. Then brake shoe 9 will insert itself between disc
11
and gear
10
braking the gearbox counter-shaft. By means of pawl 3 the brakes can
be
locked
in
this position. To
re
lease
lock
and brakes, depress knob 2 and move the
handlever downward.
