HOW TO USE THIS MANUAL

This manual is designed to provide the customer with a means to identify the parts on his/her tractor when
ordering repair parts. The illustrations may or may not represent the actual assemblies; therefore, it is
not recommended to use this manual as a guide to assemble or disassemble the tractor. Some hardware
and parts are drawn larger in order to more readily identify them.

Each tractor has its own model number.

The model number for your tractor can be found on the fender under the seat.

When ordering parts, always give the following information:

• Product - “Tractor”

• Model Number - “BA12592RBA”

• Part Number

• Part Description

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.
