“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 
fiinch. square. Furnished with ^-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., $25.50. . „ . , _

Pittsburgh Head-Rail Harrow

ment and desired slant to the teeth, thus adapting the Harrow to general 
purpose work or for finishing and smoothing operations. It will also answer

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 A-inch teeth. One-horse, with 25 teeth, one section, weight 118 lbs., $11.75; 
two-horse, with 50 teeth, two sections, weight 215 lbs., $20.50; two-horse, with 60 teeth, two sections, weight 230 lbs., $22.50.

The Clark “Cutaway” Flexible 
Tractor Harrow gives all the flexi¬ 
bility that can be desired and at 
the same time retains many of the 
valuable and exclusive Clark “Cut¬ 
away” features. This is an unusually 
sturdy Harrow with its heavy 
angle-steel and channel-steel frame 
construction. All four gangs are angled by a pow¬ 
erful crank and screw control. The rear section 
can be quickly removed by taking out three bolts 
and the front section of the Harrow used alone if 
desired. 
Farmers who want a genuine Clark “Cutaway” Disc Harrow but 
prefer the flexible type are very enthusiastic about this Harrow. 
There is a special line of Heavy Service Tractor Harrows for ex¬ 
treme conditions and extra-heavy tractors. Folder sent on request. 
Clark “Cutaway” Harrows have been continuously manu¬ 
factured for more than 50 years. They are the best that can 
be produced both in design and construction.
