280 FARM MACHINERY REPAIR 



255. Harvesting Machinery. 



Requirements: To make a careful study of grain-harvesting 

 machinery, corn binders, grain binders, shocking attach- 

 ments, push binders, headers, combines and such har- 

 vesting machinery as is used in the immediate neighbor- 

 hood. 



Tools Needed: Same as in Sec. 251. 



Preliminary Instruction: The modern harvesting machinery 

 on the farm plays a similar part in production to the au- 

 tomatic machines in the factory. They make possible 

 greater production per capita, allowing more people to en- 

 ter other lines of endeavor. The cost of production 

 where modern harvesting machinery is used is a great 

 deal less than where harvesting is done by hand method. 



Working Instruction: Follow instruction as outlined under 

 Sec. 251. 



256. Study of Power-Driven Machines. 

 Requirements: To make a careful study of power-driven 



machines used on the farm, such as grain separators, 

 silage cutters, feed grinders, corn shellers, limestone 

 grinders, cane mills and other machines in that section. 

 Preliminary Instruction: With the advent of the stationary 

 engine and the tractor on the farm, power-driven ma- 

 chines in greater numbers will be used each year. Many 

 farmers are already buying small threshing outfits where 

 formerly the grain was threshed by a large threshing out- 

 fit. Such practices make for greater efficiency and bet- 

 ter products. The grain can be threshed when in the 

 best condition, and the corn cut for silage when at the 

 proper maturity if the farmer has his own equip-
