Rice is the main staple food for half of the population all over the world. As a modern rice harvesting machine，combine harvester can complete the processes of harvesting，threshing and cleaning at one time. In China，crawler rice combine harvester is a mainstream harvester，because in southern China，there are many small and mediumsized fields. During the rice harvest season，the soil in a small area is also relatively wet and soft. There were many factors that influence soil compaction apart from soil properties，mechanical pressure，soil layer，the time of compaction and so on. Crawler rice combine harvester can effectively reduce mechanical compaction on the wet soil. However，there are few books about theory，modeling，and design of crawler rice combine harvester. This is also detrimental to the promotion and the development of crawler rice combine harvester in China.
This book is about the
theory，modeling，and design of crawler rice combine harvester. The theory，modeling，and design of this book are the results of the author and his teams research on crawler rice combine harvester for more than 10 years. There are nine chapters in this book. The first chapter is introduction to rice harvesting. In this chapter，rice maturity and properties are introduced. Readers can learn about the attributes of rice stalks，rice leaves and grains as well as the characteristics of the threshing process. From chapter 2 to 5，rice stems cutting and conveying，rice threshing and separation，grain cleaning device and conveying process are introduced. In these chapters，readers can learn about the
theory，modeling，and design of crawler rice combine harvester. For chapter 6，chapter 7，and chapter 8，humanmachine interface chassis platform is designed. When the cutting，conveying，threshing，separating equipment were integrated on chassis platform，the dynamic load and vibration during rice harvesting were analyzed. The last chapter，the rice straw harvesting method and equipment are introduced. There is a wealth of knowledge contents and new knowledge of crawler rice combine harvester in this book. These research results are of important theoretical value to the design and research of crawler rice combine harvester.
Given its engineering content based on the authors practice，this book is also recommended for other courses in Agricultural Engineering that emphasize functional analysis，design，and research in field machinery. This book is also designed to be both introductory and comprehensive for a twocourse sequence for undergraduate and graduate students，respectively. In regard to the theory，analytical techniques，engineering design expertise，and software use，this book also serves as a useful reference tool for scientists and practicing engineering professionals in academia and industry around the world.
