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 - Tractor MODEL NUMBER - UN155H92RBK ( ) Part Number Part Description TABLE OF CONTENTS SCHEMATIC...3 ELECTRICAL CHASSIS DRIVE ENGINE STEERING MOWER DECK SEAT DECALS...17 MOWER LIFT...18 BAGGER

Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. 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 power). 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. 11
