HEADLIGHTS

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.
