PREFACE TO THE SECOND EDITION
•
Many developments have occurred in the field of farm machinery in
the seven-year interval between the first and second editions of this book.
Improvements in tractor implements, espe.cially attachments for row
crop tractors, have brought about changes in farming practices that have
been largely instrumental in reducing labor requirements and production
costs.
The rapid progress in the mechanization of agriculture has made it
necessary in the' preparation of this edition to revise and rewrite the
greater portion of the text. Much obsolete material has been discarded
and replaced with new subject matter. New chapters have been added,
discussing farm machinery in its relation to agriculture, dusting and
spraying equIpment. and terracing machinery. The chapters on wagons
and motQr truc:;ks have been combined and supplemented with a treat
ment of the automobile trailer. Many of the illustrations have been
replaced, by either new or improved ones to show the latest types of
machines now available.
The dis~ussion of the developments on the mechanical harvesting of
cotton has been brought up to date, giving results of experimental work
done during the past few years. Improvements in haying machinery,
such as placing the gears in a bath of oil enclosed in a dustproof case and
the windrow pick-up baler, are described and illustrated. A number
of illustrations show machinery equipped with rubber tires, an innova-
. tion on many farm implements. In general, an effort has been made to
bring the entire sulJject matter of the text up to date and to show the
latest developments in the field of farm machinery.
The author is indebted to many farm implement manufacturers for
their splendid cooperation in furnishing descriptive literature and
illustrations. He especially desires to expr~ss his appreciation to Pro
fessors F. R. Jones and Donald Christy for their helpful suggestions and
criticisms. A sincere attempt was made to give credit wherever due, and
any oversights were not intentional.

PREFACE TO THE FIRST EDITION
This book is int~nded primarily as a text for use in farm machine
classes for agricultural and agricultural engineering students. It is al
intended as an aid to farm equipment salesmen and dealers, agricultUl
extension workers, farmers, and others interested in the introducti.
and use of labor-saving equipment for the farm. .
It has been the aim of the author to present a treatise on faJ
machinery coVering the most important types of machines used in gene]
'farming. The book opens with a discussion of the rp.ore importa
phases of physics which are of assistance in analyzing the design, Opel
tion, and adjustment of the machines taken up in later chapters. Follo
ing this is a brief description of the various elements of a farm machiJ
together with typical applications. An innovation is the chapter on t
selection of farm machinery in which are given suggestions as to the be
place to purchase the equipment.
The main part of the book is a discussion of the various types of fa]
machines, their design, construction, operation, and efficiency. M(
space is given to plows than ordinarily because of their importance
the preparation Of the seed bed for all crops. Machinery used in t
growing, harvesting, and preparation of cc)tton for the market is giv
special attention. The combined harv~ster-thresher is thQrougl
covered. The author has endeavored to arrange the discussion of thl
machines in the logical sequence in which they are usually applied to 1
farm work.
The entire field of farm machinery as applicable to this country I
been covered as fully as space will permit.
An effort was made to cover the latest types of machines develoJ
for the farm;'those machines that have proved to be economical in tb
use and instrumental in reducing the cost of production.
The author is indebted to: Dr. O. W. Silvey, of the Physics Depf
ment, and Professor E. R. Alexander, of the Department of Agricultu
Education, of the Agricultural and Mechanical College of Texas. Tha]
are also due Miss Daisy Brogdon for her' assistance in preparing
manuscript.,
