INSTRUMENTS AND CONTROLS
ENGINE SPEED CONTROL LEVER
BRAKE PEDALS -Continued
This lever controls the speed of the engine
and, when set in a given position, will maintain
a uniform engine speed even though the engine
load may vary.
Do not permit the engine to run below the
minimum idle speed for any length of time. or
operate the engine at more than the regular.
governed speed. Excessive speed is harmful.
Refer to the "Specifications'! on poge 74.
Caution! Always latch the brake pedals
together when driving the tractor in high
gear. To latch the pedals together. en-
gage the latch (located in back of the left pedal)
in the slot in back of the right pedal. When the
brake pedals are not latched together. the
latch should rest in the slot in back of the left
brake pedal.
The brake pedal lock (1IIust. 12A) is used to lock
the brake pedals in the depressed position.
This prevents the tractor from moving.

This lever is used to select various gear
ratios provided in the transmission. There
are three forward speeds and one reverse
speed. See Illust. 5. Refer to "Specifications" on
page 74.
GOVERNOR
The governor is set at the factory and
should require no adjustment. Consult your
International Harvester dealer if the governor
does not function properly.
CHOKE ROD
The choke rod makes possible the regulation
of the carburetor choke from the driver's seat.
Pulling out on the choke rod closes the carbu-
retor choke for starting the engine; pushing it
back in opens the choke.
IGNITION SWITCH (12-Volt System)
CARBURETOR CHOKE LEVER
The carburetor choke lever controls the air
supply to the carburetor. When the choke lever
(1IIusts. 9 and 9A) is moved up all the way (closed
position) the air supply is cut off, thereby en-
riching the fuel mixture for starting the engine.
If your tractor is not equipped with a cranking
motor and choke rod, move the choke lever up
all the way before cranking the engine. Moving
the choke lever back down opens the choke for
normal engine operation.
A key-type ignition switch (1IIust. 4) is lo-
cated on the instrument panel. Turn the key
clockwise to a horizontal position to turn on
the ignition. The key cannot be removed when
in this position.
Note: When the engine is not operating, or
the engine has stalled and the operator leaves
the tractor, the key must be turned to the
"OFF" position to prevent battery discharge.
PUSH BUTTON STARTING SWITCH (12-Volt System)
Pushing the button in completes the electri-
cal circuit between the battery and the cranking
motor and causes the cranking motor pinion toengage
the flywheel ring gear, thereby cranking
the engine. See Illust. 4.
