HOW TO USE THIS MANUAL
This manual is designed to provide the customer with a means to identify the parts on his/her tractor

hardware and parts are drawn larger in order to more readily identify them.

When ordering parts, always give the following information:
• Product - “Tractor”
• Model Number - “
MC19542LT (96012011400) ”
