SELECTING A GASOLINE OR OIL ENGINE 



The selection of a gasoline or oil engine for the farm is not 

 easy, owing to the many features of the problem involved. 

 First, there is the size or horsepower to be decided; second, 

 the type, involving such features as weight and speed; third, 

 the mounting; and fourth, the quality of the engine. 



The Size. The gasoline or oil engine is used on the farm 

 for many purposes at the present time, and the power 

 requirements for these various purposes differ widely. The 

 following list gives the more common uses for the gasoline 

 engine and indicates the approximate amount of power 

 required : 



Washing machine, 3^ to 1 H.P. 



Churn, 1 to Y 2 H.P. 



Pump, Y 2 to 2 H.P. 



Grindstone, Y 2 to 2 H.P. 



Electric generator, 1 H.P. or more. 



Feed mill, 3 H.P. or more. 



Portable elevator, 3 to 5 H.P. 



Corn sheller, 2 H.P. or more. 



Ensilage cutter, 5 to 25 H.P. 



Threshing machine, 6 to 50 H.P. 



It is to be noticed that the first four machines require a 

 rather small engine, while the others either require consider- 

 ably more power, or they may be operated more advan- 

 tageously when of a size suitable to a medium-sized engine. 

 The feed grinder may be obtained in almost any size; but 

 where magazine bins are not provided and where it is expected
