“Columbian” Steel Lever Harrow 
ONE- AND TWO-HORSE 
The Columbian Harrow is made with lever adjustment, so that the teeth can be changed to 
any slope quickly and with little exertion on the part of the operator. 
The main-bars are U-shaped, and made especially for Harrow purposes, 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, and any size can be used, from ^inch square to 
^inch square. Furnished with j^-inch teeth. The stirrup- 
bolt clamp is fixed to take the common stock 
teeth carried by all dealers. It is securely 
braced and nicely finished. One-horse, with 25 
teeth, one section, weight 125 lbs., $13.25; 
two-horse, with 50 teeth, two sections, weight 
230 lbs., $23.50; two-horse, with 60 teeth, 
two sections, weight 260 lbs., $25.75. _ . _ _

ment and desired slant to the teeth, thus adapting the Harrow to general

The heavy solid steel hitch-bar across the front braces the Harrow securely 
and is provided with malleable hitch-hooks. Harrow has flat runners, and 
the close-fitting back boxing in connections with “U” stirrup makes a 
very secure tooth-fastening. Furnished with ^--inch teeth. One-horse, with 25 teeth, one section, weight 118 lbs., $11;
