160 HOW TO MAKE SILAGE. 



will be seen, therefore, that unless proper speed be main- 

 tained there will be no elevation of the material what- 

 ever. If the power at hand is not sufficient to maintain 

 full speed when the cutters are fed to full capacity, all that 

 is necessary is to feed the machine accordingly, in other 

 words, to cut down the capacity to the point where full 

 speed can be maintained, as is necessary with other kinds 

 of machinery, such as threshing machines, grinding mills, 

 etc. 



In setting a Blower Machine it is necessary to have 

 the pipe as nearly perpendicular as possible, so that the 

 current of air within the pipe will lift the material. This 

 is especially true where the pipe is long, say 20 feet or 

 more, because the green fodder being heavy will settle 

 down onto the lower side of the pipe, if this has much 

 slant, and the wind blast will pass over the fodder, thus 

 allowing it to lodge, whereas if the pipe be perpendicular, 

 or nearly so, no stoppage will occur. It is also necessary 

 to see that full speed is attained before beginning to 

 feed the machine, and also to stop the feeding while the 

 machine is in full motion so that the Blower will have 

 an opportunity to clear itself before shutting off the power. 



There must be ample vent in the silo to prevent back 

 pressure, as the tremendous volume of air forced into the 

 silo with the cut fodder must have some means of escape. 



If these few points are kept in mind, there can be no 

 possible doubt as to the successful operation of the Blower 

 Elevator; and, as previously stated, there is absolutely no 

 doubt as to their superiority for elevating silage. Scores 

 of "Ohio" Blower Machines are in successful use in all 

 parts of the country.
