NOTE
YOUR TRACTOR
IS
EQUIPPED
WITH A SPECIAL
ALTERNATOR
SYSTEM.
THE LIGHTS ARE NOT
CONNECTED
TO THE
BATTERY,
BUT HAVE THEIR
OWN ELECTRICAL
SOURCE.
BECAUSE
OF THIS, THE
BRIGHTNESS
OF THE LIGHTS
WILL CHANGE WITH ENGINE
SPEED.
AT IDLE THE LIGHTS
WILL DIM. AS THE ENGINE IS
SPEEDED
UP, THE LIGHTS
WILL BECOME THEIR BRIGHTEST.
