PERENNIAL FORAGE GRASSES 45 



Hay loaders are of two general types: 



A. In one type the hay is picked up from the swath or 

 windrow by means of a gathering cylinder, from which it is 

 conveyed by means of a carrier to the load. 



B. In the other type the rakes engage the hay, moving it 

 forward and upward, where it is engaged by the revolving teeth, 

 which automatically push 



up and let go as suc- 

 ceeding teeth engage the 

 hay. 



Each type has its ad- 

 vantages and disadvan- 

 tages. The last men- 

 tioned type pushes the 

 hay constantly forward; 

 as there is no return car-

rier which tends to drag 



the hay backward, it is easier for the loader. On the other 

 hand, the first mentioned type agitates the hay less and hence 

 is less likely to break off the finer and more valuable parts. 



42. Stacking. Where hay is placed in the barn, a wooden 

 or iron track is usually placed in the ridge of the roof on which 

 a hay carrier runs. The hay is thus elevated from the load by 

 horse power to any desired height and dropped at a convenient 

 spot for distribution in the mow. 



Different devices are used where it is desired to place the 

 hay in stacks ; A and B show forms that may be used by cutting 

 poles from the woodlot and using the same rope that was em- 

 ployed in putting the hay into the barn, with some additional 

 guy ropes. In D a separate wire rope is used, on which runs 

 an ordinary rope hay carrier. 



The large swinging hay derricks C are used in the alfalfa 

 regions in the West where it is desired to build large stacks. 

 The hay stackers E are used when the hay is stacked in the
