Description
This trusted text provides a thorough introduction to agricultural mechanics, covering fundamental mechanical and engineering theory, common tools and materials, and a wide range of practical applications. Units explore essential topics such as career opportunities, shop orientation and procedures, woodworking and metal working, tool fitting, project planning, cutting and welding, paints and paint application, power mechanics, electrical wiring, plumbing, hydraulics, concrete and masonry, and agricultural structures. Safety is also emphasized strongly throughout the text, both within each chapter and in a dedicated unit. To engage today's students and make even complicated principles easier to apply, the text features abundant, full-color images, illustrations, charts, and data tables, as well as detailed drawings of over 50 complete project plans. More than 300 of these visuals have been added or updated for the Seventh Edition, which also boasts a suite of dynamic digital teaching resources, such as an online Coursemate with lecture materials, videos, interactive quizzes, and more. The new edition also includes updates to reflect the latest innovations in materials, machinery, and methods, providing a current and comprehensive guide to help students plan and execute agricultural projects effectively.教学资源：PPT、教师手册、题库。
