SWEET CLOVER: HARVESTING AND THRASHING SEED CROP. 



the lower part of this extension should be flattened as much as possi- 

 ble, so that it will not interfere with the upper portions of the plants 

 as they pass from the platform to the elevators. The opening must be 

 sufficiently large, however, to permit small branches and racemes 

 which fall upon the extension to pass into the pan. The angle of the 

 lower portion of it must be large enough to permit the seed to run 

 directly into the pan below. If this portion is sloped from the seat 

 pipe to the opening between the platform and the lower elevator no 

 trouble will be experienced. This extension may be bolted to the 



machine by drilling ^ _ /7 ,- __^. 



holes in it to coin- 

 cide with those in the 

 elevator plate. 



It is necessary to 

 widen the binder 

 deck, so as to save 

 the seed which is 

 shattered from those 

 portions of the plants 

 which extend beyond 

 it. This may be done 

 by bolting to the rear 

 end ~of this deck an 

 extension, as shown 

 in detail in figure 9. 

 This extension may 

 be made from one 

 piece of galvanized 

 iron, which should be 

 cut along the solid 

 lines and of the size 

 shown in figure 9, J.. 

 It should be bent 

 upward and slightly inward at the dotted lines shown in this 

 figure. The extended strips, as shown in figure 9, B, should be 

 riveted to the mam part of the extension. When this is done a 

 trough will be formed along the side and lower end of it, so that all 

 seed which shatters upon it will be directed into the pan below the 

 deck. The object in riveting the extended strips at the end of the 

 extension to the main part is to prevent the tops of the plants from 

 catching in the trough when the bundles leave the packers. It may 

 be necessary to fasten a brace to the bottom of the deck to support 

 this extension. This can be done,, however, by using a strip of 

 strap iron or wood. The upper end of this extension should be bent
