Stackers. Field hay stackers are divided into two classes, 

 the plain overshot and the swinging stacker. The first has 

 a row of teeth, corresponding to the teeth of the sweep rake, 

 on the end of long arms hinged near the ground. The hay 

 is left upon these teeth by backing away the sweep rake. By 

 means of a rope and pulleys the teeth are raised to a vertical 

 position and the load of hay allowed to slide back onto the 

 stack. The objections of this type of stacker are that the 

 hay must always be raised to a certain height regardless of 

 the height of the stack, and the hay is always dropped in the 

 same place on the stack, causing it to settle unevenly. 



The swinging stacker has a row of teeth on arms which 

 may be raised to any height and locked in place by a brake 

 engaging the rope ; then the hay may be swung over the stack 

 and dumped. As there is some choice as to where the load 

 may be dumped, this style of stacker offers several advan- 

 It may also be used in loading hay onto the wagons.
