or below so as to raise the outer or the inner edge 

 of the idler pulley, will not change the position of the belt 

 on the pulley It must be put under the front or rear part 

 to accomplish the desired result, as this will divert the 

 course of the belt slightly on its way to the pulley. 



Stack Building with Wind Stacker. Where it is desir- 

 able to stack the straw so as to preserve it, the wind stacker 

 must be handled by a competent man. In starting the 

 stack, bring the chute about level, extend it to its full 

 length, raise the hood slightly, and build the back of the 

 stack first. Always keep the farther side of the stack 

 highest. Make the stack bottom at least one-third smaller 

 than would be done were it built by hand, and allow the 

 straw chute to oscillate. It is very important that the 

 farther side of the stack be kept highest, as it furnishes 

 a back wall to stop the force of the straw. A good rule 

 to follow is: "Always throw the straw onto the stack 

 and not over it." In topping out, allow the straw to strike 

 the top and glance over it ; in this way the farther side of 

 the stack will be filled out and the straw will be prevented 

 from rolling down or going over too far. When the 

 straw chute is at the corner of the stack, raise and lower 

 hood quickly, thereby distributing the straw and binding 

 ths corner. 



Lubricating the Wind Stacker. Keep the bearings 

 of the driving shafts well lubricated with hard oil, espe- 

 cially the one next to the pulley. The bevel-gears driving 

 fan on geared stackers must be kept well greased. All
