ISO . SCIENCE OF SUCCESSFUL THRESHING. 



to have the belt run properly on the pulleys. To prevent the 

 belt from drawing the stacker ahead, at least one of the truck- 

 wheels must be blocked. The block for this purpose should 

 be carried with the machine so that it will not be necessary 

 to hunt one each time the stacker is set. 



Operating the Independent-Stacker. The length of 

 swing is governed by trip-pins and will be readily understood. 

 Before leaving the machine with a stack part way up, it is 

 best to lower the carrier until it rests on the stack, so that in 

 case a wind springs up, the stacker will not be in danger of 

 being upset. The carrier should be folded and lowered 

 until it rests on its supports before moving from place to 

 place. No special instructions are necessary in respect to 

 lubrication, except, perhaps, to call attention to the fact that 

 the bearings of the rake-drive-shaft boxes should be fre- 

 quently oiled. 



The Wind Stacker has steadily increased in popularity 

 until to-day there afe more of them sold than of all the 

 various other varieties of stackers combined. The wind 

 stacker was extremely popular with the threshermen from 

 the first, because of its freedom from "trappy" features, the 

 absence of dust and litter about the separator equipped with 

 it, and the ease with which the chute is swung around on 

 the deck of separator for transportation. 



Operating the Wind Stacker. To make the chute swing 

 automatically, the two inch belt must be put on to drive the 

 turret and if the clutch, which is operated by a rod handle
