While tractors and automobiles are the same in general principles, there is a wide difference between them in design, construction, and handling, due to the differences in the w...

The engine gets its power from the burning of a mixture of fuel vapor and air. When this mixture burns, it becomes heated, and, as is usual with hot things, it tries to expand,...

The foundation of an engine is the _base_, which supports the _bearings_ in which the crank shaft revolves, and to which the cylinders are attached. The cylinders of tractor eng...

In order that a thing may burn, it must be provided with oxygen. Oxygen is found in air, so it is usual to say that air is necessary in order that anything may burn.

The apparatus that forms the mixture is in two parts, one being the carburetor that proportions the fuel to the quantity of air drawn into the cylinder, and the other the _mixin...

In order that a gas engine may run properly, the mixture must be set on fire, or _ignited_, at exactly the right time; if ignition occurs too early or too late, there will be a...

While the greater number of tractor engines use magneto ignition, many use battery and coil systems, which are the same in general principle as magneto systems, but produce magn...

It has been shown that a gas engine delivers power only when it is running at speed; it cannot run until some outside power drives it through the inlet and compression strokes.

The uneven ground over which tractors must work requires the weight to be kept low, to prevent capsizing, and they are also built wide, for the narrower they are the more easily...

The most important thing in the care of a tractor is to oil it; every moving part should be lubricated, and the greatest care should be taken to assure a never-failing supply of...

Before running a new tractor it should be given a careful examination to make sure that all nuts and bolts are tight, and not secured only by paint; that all grease cups are in...

The operation of a carburetor depends on so many things that no exact instructions for its adjustment can be given. The best that can be done is to give a general idea of the re...

There are many ways in which an engine can give trouble, but these are not serious to an operator who understands the action of an engine, and who works with his brain as well a...
