TRANSMISSION OIL TEMPERATURE
WARNING LIGHT
Ford 420 and 535
Tractors equipped with a 4-speed power reversing trans-
mission have a transmission oil temperature warning light,
Figure 7. When the key-starter switch is turned "ON,"
the temperature light will come on. When the engine is
running, the light will go out. If the light comes on
during operation, idle the engine at 1000
to 1200 rpm,
with the gearshift levers in neutral, until the transmission
has cooled and the light goes out.
CHARGE INDICATOR LIGHT
The charge indicator light is shown at (9), Figure 6.
When the key-starter switch is turned "ON," the charge
indicator light will come on, indicating that the light is
functioning. When the engine is running, the light should
go out as engine speed is increased. If the light remains
on, it is an indication that the alternator is not charging
the battery. Investigate immediately, otherwise the
battery may become discharged.
PROOF-METER
The Proof-Meter (2), Figure 6, indicates:
at a slower rate than clock hours. Engine speeds above
1666 rpm build up hours faster than clock hours. Use
the Proof-Meter as a guide to determine hourly service
and maintenance intervals.
•
the engine revolutions per minute. Use the Proof-
Meter in conjunction with the transmission shift decal
to determine the tractor ground speed. The Proof-
Meter also is helpful when operating P.T.O. equipment.
Additional P.T.O. and ground speed information can
be found on pages 22 and 71.
FUEL SHUT-OFF VALVE
The fuel shut-off valve is located at (2), Figure 8. Rotate
the valve clockwise to close; counterclockwise to open.
BRAKE CONTROLS
BRAKE PEDALS
The two brake pedals and the brake pedal lock are shown
in Figure 9. Depress both brake pedals simultaneously
to brake both rear wheels and stop the tractor.
The pedals can be operated independently to assist in
making sharp turns at slow speeds.
•
the hours and portions of hours your tractor has
operated, based on an average engine speed of 1666
rpm. Engine speeds below 1666 rpm accumulate hours
CAUTION: When operating the tractor
at road speeds, do not attempt to make
short turns by using the brakes.
