 Requirements: To assist in the various operations of har- 

 vesting hay from cutting to baling. To determine the

 finally, to determine cost of producing a ton of hay. 





FIG. 311. Using a hay loader. 



Equipment Needed: Mower, rakes, loaders, balers and power. 



Preliminary Instruction: Hay is a crop that has to be made 

 while the sun shines. It must be cut at the right time, 

 and cured to the right degree before it can be stacked, 

 stored or baled. Handling of the hay depends much on 

 the weather. The condition of the crop must also be 

 considered. The proper time to cut alfalfa and other 

 hay crops will be taken up in the study of crops.
