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 - “M1638 (96011021301)”
• Part Number
• Part Description

YOUR TRACTOR IS

THE LIGHTS ARE NOT

WILL CHANGE WITH ENGINE
SPEED. AT IDLE THE LIGHTS
WILL DIM. AS THE ENGINE IS
SPEEDED UP, THE LIGHTS
WILL BECOME THEIR BRIGHTEST.
