SWEET CLOVER: UTILIZATION.

The forward end of the shoe sole to be used on the outer shoe 

 should be tapered gradually to 1 inch from the end. The forward 

 inch should be one-fourth of an inch in width and bent slightly up- 

 ward and inward, so that a hook will be formed to fit into the slot 

 in the front end of the shoe. (Fig. 7, B.) The rest of the sole should 

 be curved, so that it will run smoothly on the ground when the cutter 

 bar is set to cut at different heights. The upright which is bolted 

 to the sole should preferably be made of three-eighths by 1 inch 

 material and should have six holes, 1 inch apart, bored in it, so that 

 the outer end of the cutter bar may be raised to the same height as 

 the inner end. On practically all standard makes of mowers the 

 outer shoe sole hooks into the shoe instead of bolting to it, as is the 

 case with the inner sole on some machines. A wheel is used in place 

 of a shoe sole on the outer end of the cutter bar on some machines. 

 When this is the case, the upright to which this wheel is attached 

 should be lengthened. On other machines the forward end of the. 

 sole hooks into a slot in the shoe in the same manner as the inner 

 sole. In this event the front end of the sole should be bent slightly 

 upward and outward. (Fig. 7. ('.} 



Before shoe soles are made for any mower a careful examination 

 should be made of the shoes to determine the exact size required 

 and the manner in which they should be attached to the forward 

 ends of the shoes. 



CURING AND HANDLING SWEET-CLOVER HAY. 



One of the greatest difficulties in curing sweet clover is the fact 

 that- the plants usually are ready to be cut for hay at a time of the 

 year when weather conditions are likely to be unfavorable for 

 haymaking. Little trouble is experienced in curing this crop in the 

 drier sections of the country where the methods used for alfalfa are 

 employed. The curing of sweet clover is more difficult than the 

 curing of either red clover or alfalfa, as the leaves are very apt to 

 shatter before the stems are cured. Every possible means should be 

 employed to save the leaves, as these constitute the best part of the 

 hay. \SeeTableIL)
