Operating Techniques for the Tractor-Loader-Backhoe Published by: Equipment Training Resources This revised edition of a classic operation manual explains standard machine operations for the tractor-loader-backhoe. How to work with weight distribution, momentum, pitch of slope, and center of gravity. It covers all the important issues of safety and maintenance. Then it delves into the work - how to dig around utilities, plan jobs, as well as set-up techniques, grading and compaction techniques, trenching procedures, loading material, clearing land, and demolition methods. This practical book is filled with illustrations, photos, and sample tests you need to help you master practically all the techniques and usages of this versatile machine. 1.

It's ideal for most of the trenching that's done on a building site. It's perfect for loading soil and heavy objects into a truck. It handles light demolition well. And, of course, it backfills trenches and does minor grading much faster than could be done by hand. This book isn't a technical manual. And it doesn't cover any particular type of TLB. The various manufacturers have all the technical manuals you'll need on the equipment they manufacture and sell. Nor does this book recommend one brand of TLB over any other. They're all good. What this book does is explain in the most concise and direct way possible what you should know for safety and productivity of the TLB. Without this information, you may not be aware of the potential for accidents, and the safety hazards that can cause serious damage to people or property. As you read through the first chapters, you may feel that my descriptions seem to cover a series of unrelated subjects and procedures. Be patient and learn these important principles as they are presented. As you read further, you will notice that each bit of information becomes a part of a larger process. Later sections of this book emphasize the more technical aspects and difficult job situations, such as: tight work space, working around utilities, precision excavation and many more complicated tasks. Although many jobs do not demand the highest degree of operating skills, mastering the machine provides safety as well as the necessary skills to do precision work. Learn the more demanding tasks and everything else will seem like a piece of cake. That's why I've emphasized techniques and work procedures that cover "worst-case" situations. A word to beginners: There's no substitute for practice, practice and more practice. Just reading this book isn't enough. It's practicing what you've learned here that makes you an expert. With time, operating a backhoe safely and productively will become as natural to you as driving a car or tying your shoe. And don't be discouraged when you run into difficulty. The TLB is among the most difficult pieces of heavy equipment to operate. There are two reasons: First, it's really two machines in one, with separate controls and operating principles for each. Second, the TLB is used for so many different tasks and procedures, that there's a lot to learn. No matter how experienced you are, there's always another job yet to be attempted and mastered. And remember, it is the operator's job to find an intelligent, safe, workable solution to the job at hand. The Answer Key on pages 285-296 is perforated for easy removal, if desired. If you choose to remove these pages, please return them to the students at the end of the course as they are an excellent review of the material. These machines are commonly called on for wide range of tasks, procedures, and applications. Because of these wide ranging uses, I have used terminology that will convey the exact thought of the author to the reader. When "TLB" is used in this book, I am referring to the machine in general. When the word loader is used in this book, I am referring to the machine being used as a loader, moving on the site and using the loader bucket to perform work. The machine could be grading, leveling, moving material, or loading trucks. When the word backhoe is used in this book, I am referring to the machine being used as a backhoe, with the stabilizers down and the machine in a set position.
