2 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 - Lawn Tractor Model Number - BM155B107HK ( ) Part Number Part Description TABLE OF CONTENTS SCHEMATIC...3 ELECTRICAL CHASSIS AND ENCLOSURES DRIVE STEERING ASSEMBLY ENGINE MOWER DECK MOWER LIFT SEAT ASSEMBLY...1 DECALS...19

Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual on-site or net horsepower). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine. 13
