FOREWORD
The tractor of to-day is built in almost as many types and designsas there are tractor makers, and is far from being as standard asthe automobile. There are tractors with one driving wheel, with twodriving wheels, with three and with four, as well as three arrangementsof the crawler principle; there are two-wheelers, three-wheelers andfour-wheelers; tractors that are controlled by pedals and levers andtractors that are driven by reins.
Thus if a man who is competent to handle and care for one make is givenanother make to run, he may be entirely at a loss as to how it worksand how it should be handled.
It is the purpose of this book to explain and describe all of themechanisms that are in common use in tractor construction, to the endthat the reader may be able to identify and understand the parts ofwhatever make he may see or handle.
