CLUTCHAND BRAKE PEDAL
Note: Do not rest your foot on the pedalwhile
driving the tractor,
as this will result
in excessive
clutch lining wear.
The combination
clutch and brake pedal is
used to disengage the engine from the transmission when shifting gears and to actuate the
brake to stop the tractor.
The pedal must be
pressed
all the way down to activate the safety
starting
switch when starting
the engine.
Always
be sure the rear wheels
are free
to turn.
Under
any adverse
conditions,

of going forward.
To disengage the clutch,
press the pedal
approximately
half way down. To stop the tractor press the pedal all the way down.

PNEUMATIC TIRES

REAR WHEELWEIGHTS
Rear wheel weights increase traction and
reduce wheel slippage. The weights weigh
approximately 26 pounds each. They are
attached to each rear wheel with two bolts,
lock washers, and hex. nuts.
Inflate the front and rear tires for normal
or heavy load operations
as shown in the fol-
lowing table.
If additional weight is desired. a second set
of weights can be attached to each first weight
by using two longer bolts.
MOUNTINGTIRES ON THE RIM
TIRE CHAINS
After mounting a new or old tire on the
rim, inflate it to 20 pounds pressure
to seat
the tire bead on the rim flange and to prevent
the tire from creeping and shearing
off thevalve.
Then deflate the tire to the correct
operating pressure.
Tire chains will provide additional
traction
for wet ground conditions,
when plowing snow,
or pulling heavy loads. Rear wheel weights
are recommended
when using chains.

CLUTCH AND BRAKE
(International Cub Cadet 71, 102 and 122 Tractors)
As the clutch and brake are both operated
by the same pedal, care must be taken to
maintain a neutral zone so the clutch is disengaged when the brake is applied.
ADJUSTINGTHE CLUTCH
It is important
that a clearance
of .050inch be maintained
between the clutch release
lever and the clutch release bearing.
In order
to maintain this clearance.
the pedal should
have a free movement of approximately
3/16inch. SeeIllust. 21. This measurement
is taken
at the point of contact of the pedal arm withthe
front edge of the pedal return stop.

are set at the

and should
not require
frequent
attention unless
the linkage

or
when the pedal movement

3/16-inch.
When it is necessary
to adjust
the
clutch,
turn the adjusting
nut "A" on the clutch
release
rod (1IIust. 22) in or out as required
to
get the proper
measurements.
ADJUSTINGTHE BRAKE
The brake should engage when. the pedal
arm is pressed down to within a maximum
of
l-5/l6-inches
and a minimum
of 3/4-inch
distance above the top of the left foot support,
which serves as the pedal stop. SeeIllust. 21.
It may be possible to push the pedal all the
way down to the pedal stop, but this is of no
concern as long as the brake is engaged when
the pedal arm is at least 3/4-inch
above the
pedal stop.
