GEDDES AND SCOTCH HARROWS. 



143 



Fijr. 151. 



The Geddes Harrow is one of the best in use for rough or 

 uneven land. The teeth being situated considerably back 

 of the point of draught, its motion is even and steady, 

 and easy for the team. In conse- 

 quence of its wedge-form, it passes 

 obstructions more readily. The 

 center or draught-rod forms a set 

 of hinges, by which it becomes 

 adapted to uneven ground, or by 

 which it may be easily lifted to 

 discharge weeds, roots, or other 

 obstructions. Or it may be doubled 

 back, and carried easily in a wagon. 

 The accompanying figure (fig. 150) 

 Geddes Harroic. renders its construction intelligible, 



without further description. To prevent its 

 rising in the middle, as it has been found to do 

 when the draught traces are as short as easy 

 draught requires, the chain is attached to the 

 bar on each side, as shown in fig. 151. 



The Square Harrow admits of a larger number of teeth, 

 and when made in the best form, effects thorougli pulveri- 

 zation on smooth land, free from obstructions. A modifi- 

 cation known as the Scotch 

 liarrow, represented in fig. 

 152, has forty teeth, inserted 

 in such a manner that each 

 tootli forms a separate track, 

 as shown by the dotted lines. 

 The hinges, as m all square 

 harrows, enable it to fit a 

 rolling or uneven surface, 

 and it may be folded for 

 carrying in a cart or wagon. 



For the fine pulverization of a smooth surface, a 

 erreater number of teeth has been found to answer an 



Scotch or square harrow.
