METHODS OF PLOWING 137 



fall seeding of grain. These cases, however, are 

 very rare, as compared with the almost universal 

 experience that thorough plowing is the best prep- 

 aration of a seed bed. 



USEFULNESS OF THE DIFFERENT KINDS 

 OF PLOWS 



There are a number of distinct types of plows, 

 each of which is adapted for certain conditions. 

 Furthermore, there are many makes or brands of 

 each class of plows and these differ widely in 

 construction and in value. The merits of the five 

 most important classes of plows landslide, swivel, 

 sulky, disk and gang will be discussed briefly. 

 When it comes to choosing between the different 

 makes of the same type of plow, the buyer must 

 scrutinise the construction of each, especially the 

 mouldboard, as advised in preceding paragraphs. 



The Landside Plow is the oldest and most com- 

 mon type of plow. Probably five-sixths of all the 

 plows used in the country belong to this class. It 

 turns a furrow only in one direction , usually to the 

 right; and more perfectly than swivel plows, which 

 turn the furrow in either direction. It leaves a 

 dead-furrow, which is no disadvantage on most 

 land, as it assists in drainage. 



The Swivel Plow is constructed so that a furrow 

 may be turned to the right or to the left, thus mak- 

 ing it possible to plow a field so that all the furrows 

 are turned one way and no dead-furrows are left. 

 It is especially adapted for plowing hillsides, be- 

 cause it leaves no dead-furrow to collect water. For 

 this reason it is sometimes called the hillside plow. 

 For general purposes, however, it is not usually 

 considered quite as efficient as a landside plow.
