HARROWS 101 
SPIKE TOOTH HARROWS 
“Columbian” Steel Lever Harrow 
The Columbian Harrow is made with lever adjustment, so that the teeth can be changed to any 
slope quickly. The main-bars are U-shaped, and made from an extra quality of steel, very high in carbon, 
which insures it against bending, even under the most severe strain. The cross-bars and braces are 
rolled flat from same kind of material. Great pains have been taken in preparing the patterns for the 
different parts, so that when put together they will be free from “lost motion,” and respond quickly 
to the action of the lever. 
The tooth-clamp is without doubt the best yet devised and 
consists of stirrup bolt and back and front boxing. When fastened 
with this device, the teeth would not be more rigid if a part of the 
bar itself. Teeth can be raised or lowered any distance. Furnished 
with 
^-inch teeth.
