43. Hay Forks. The general types of forks for unloading 

 hay are shown in this paragraph and do not need further 

 description. The harpoon forks are generally most popular 

 where the hay is long 

 and thus holds together 

 well, as in the case of 

 timothy hay; while for 

 clover and alfalfa the 

 grapple or derrick hay 

 fork is frequently pre- 

 ferred. In some cases 

 rope slings are used. 

 They are made in the 

 form indicated in E, or 

 consist of single pairs of 

 ropes with suitable rings 

 at the ends. One pair of 

 ropes is placed length- 

 wise of the wagon, and 

 a fourth of a load of hay 

 is put on; then another 

 pair of ropes is adjusted 

 and another fourth of 

 the load is added; and 

 so on until the load is 

 completed. The hay is A Doub]e harpoon fork . B slngle harpoon fork . c

four slmgfuls, thus ma- 

 king the unloading quite rapid. The disadvantages are that 

 time must be taken to adjust the ropes, and, in case of an ac- 

 cident, in unloading much hand labor may be required to build 

 the hay over the slings again.
