CHAPTER XXVII 

 How TO STUDY FARM MACHINERY 



250. Three Methods of Approach. Three classes of 

 projects can be worked out to meet the need of the student 

 when studying farm machinery. The first class can hardly be 

 termed projects, but exercises or studies of various types of 

 farm implements and power machines. In taking up these 

 exercises, students will be expected to obtain a general knowl- 

 edge of all kinds of machinery and make a careful study of 

 those machines used on the home farms. They will be ex- 

 pected to secure booklets describing particular machines un- 

 der discussion; these booklets may be obtained from manu- 

 facturers or from local dealers. The machines are studied on 

 the implement dealer's floor, in farm-machinery sheds, or in 

 th e school shop. Most of this work would be done during the 

 time of year when the weather will not allow outdoor work. 



The second type of project is the study of the machine 

 while operating under actual farming conditions, the student 

 being given a chance to make adjustment as well as actually 

 operating the machine. A study of the cost of doing the job 

 is carried out in this connection. It may be preparing the 

 the seed bed, planting the grain, or harvesting. Each step 

 is studied, the work is actually done, the time required for 

 it and the cost noted. 



The third type of project is a study of the care, adjustment 

 and repair of machinery. Not only can this problem be 

 studied by visiting various farms and studying conditions,
