Book Description
A field machinery selection model for multiple cropping (MACMACEL) was developed to assist in the minimization of the total cost of owning and operating machinery by selecting the optimal system size for a variety of field crops. The model was simulated by a user-friendly computer algorithm installed on a microcomputer using Fortran 77 language. It starts by determining the optimum machinery sizes for a known cropping pattern and a set of farm machinery. This consists of tractor(s), self propelled machine(s), and tractor drawn implements. the model can take into account equipment(s) that are already owned by the farmer. Trials (iterations) are made with various numbers and sizes of machines to obtain the most economical machinery set that can finish all farming operations specified within the given time, satisfy power requirements, and have the least total annual equivalent cost. For that set of machinery, printed output includes the schedule of field operations, the quantity and type of machines and implements, and itemized list of the cost based on the cash flow method.

Book Description
Despite the fact that the farmer spends more on machinery than anything else except the land and despite the fact that he spends more on tractors than on any other machine, there are few books on the choice and operation of tractors to fit modern farming conditions. Most of this book is about farming and how to fit tractors to the individual situation. Those sections are completely unbiased and Case are happy to sponsor such a book in the wider interests of sensible, more productive and safer use of tractors and machinery. Where the Company's views are expressed it is clearly stated as such. This is mainly in the area of design detail and then only for the sake of being concise and brief. The first part of the book is concerned with relating the needs of the individual farm to specific details of tractor performance. Later chapters deal with policy on size, numbers and replacement. This section is a major development specifically about tractors. It is developed from the author's work Farm Mechanisationfor Prl!fitwhich deals with machinery in the wider sense. Later chapters of this book are related to profes sionalism in operation, maintenance and care.
