This textbook offers a comprehensive review of tractor design fundamentals. Discussing more than hundred problems and including about six hundred international references, it offers a unique resource to advanced undergraduate and graduate students, researchers and also practical engineers, managers, test engineers, consultants and even old-timer fans. Tractors are the most important pieces of agricultural mechanization, hence a key factor of feeding the world. In order to address the educational needs of both less and more developed countries, the author included fundamentals of simple but proved designs for tractors with moderate technical levels, along with extensive information concerning modern, premium tractors. The broad technical content has been structured according to five technology levels, addressing all components. Relevant ISO standards are considered in all chapters. The book covers historical highlights, tractor project management (including cost management), traction mechanics, tires (including inflation control), belt ground drives, and ride dynamics. Further topics are: chassis design, diesel engines (with emission limits and installation instructions), all important types of transmissions, topics in machine element design, and human factors (health, safety, comfort). Moreover, the content covers tractor-implement management systems, in particular ISOBUS automation and hydraulic systems. Cumulative damage fundamentals and tractor load spectra are described and implemented for dimensioning and design verification. Fundamentals of energy efficiency are discussed for single tractor components and solutions to reduce the tractor CO2 footprint are suggested.

Small but mighty – a comprehensive guide to the use of two-wheel tractors for gardeners, homesteaders, landscapers, and farmers More affordable than four-wheel tractors and infinitely more versatile than single- purpose power equipment such as rototillers, two-wheel tractors are an ideal solution for an astonishing array of garden, landscaping, and agricultural applications. Two-wheel tractors are multifunctional, economical, practical, maneuverable, portable, and low impact. Yet choosing the equipment is only half of it, the other half is integrating the right machine and implements into your land-based enterprise and coupling it with innovative high-efficiency techniques. Coverage includes: Why you need a two-wheel tractor Two-wheel tractor essentials including tractor implement options and functions Equipment decision-making to suit your scale, context, enterprises, and budget Safety equipment, operation, and basic maintenance Innovative use strategies including micro-plowing, making permabeds, in situ mulching, compost-a-path design, crop guilds, scaling up, and diversified crop management How to start from scratch, clearing new land, scaling up your enterprises and more Case studies and rich examples from suburban landscaping to commercial market gardens from Europe to North America. "Pro-tips" and sidebars for rapidly elevating your skills. The Two-Wheel Tractor Handbook shows small-scale growers how to leverage walk-behind tractors to maximize the productivity and profitability of their enterprises. This full-color, highly illustrated guide is a must-have tool for urban farmers, suburban gardeners, rural homesteaders, orchardists, landscapers, and market gardeners looking to boost production.

At Clay Bottom Farm, author Ben Hartman and staff practice kaizen, or continuous improvement, cutting out more waste--of time, labor, space, money, and more--every year and aligning their organic production more tightly with customer demand. Applied alongside other lean principles originally developed by the Japanese auto industry, the end result has been increased profits and less work. In this field-guide companion to his award-winning first book, The Lean Farm, Hartman shows market vegetable growers in even more detail how Clay Bottom Farm implements lean thinking in every area of their work, including using kanbans, or replacement signals, to maximize land use; germination chambers to reduce defect waste; and right-sized machinery to save money and labor and increase efficiency. From finding land and assessing infrastructure needs to selling perfect produce at the farmers market, The Lean Farm Guide to Growing Vegetables digs deeper into specific, tested methods for waste-free farming that not only help farmers become more successful but make the work more enjoyable. These methods include: Using Japanese paper pot transplanters Building your own germinating chambers Leaning up your greenhouse Making and applying simple composts Using lean techniques for pest and weed control Creating Heijunka, or load-leveling calendars for efficient planning Farming is not static, and improvement requires constant change. The Lean Farm Guide to Growing Vegetables offers strategies for farmers to stay flexible and profitable even in the face of changing weather and markets. Much more than a simple exercise in cost-cutting, lean farming is about growing better, not cheaper, food--the food your customers want.
