John Deere Model "B" Disc Harrow 



Field Scene Model "B" Disc Harrow 



CORRECT 



CULTIVATION 



COUNTS 



It means healthy 

 and rapid growth 

 of seed. Seed, in 

 order to develop, 

 requires nourish- 

 ment just the same 

 as does anything 

 else. Give it a seed 

 bed where it can get 

 this nourishment 

 easily and quickly. 

 Use a disc harrow 

 both before and 

 after plowing. You 

 will then get maxi- 

 mum returns. 



THE MODEL "B" 



is the harrow that makes the seed bed just right 

 for the rapid development of the grain. It makes 

 a better seed bed than any other harrow because 

 it has the improvements which enable it to do so. 

 The Model "B" is the 

 only spring pressure, 

 and therefore the only 

 flexible harrow built. 

 This gives you great- 

 er penetrating power 



and more thorough indestructible 



cultivation at an even 

 depth than is secured by any other such implement. 



THE FLEXIBLE HARROW 



It is the only harrow that thoroughly cultivates the 

 ground. This thorough work is made possible by 

 the patented spring pressure which compels the 

 discs to cut at an even depth. Its two gangs arc 

 independently adjustable. In the field, only that 

 part of the Model "B" passing over an 

 obstruction is raised out of the ground, 

 while the balance continues to do its work. 

 With a rigid harrow the entire implement 

 is lifted out, leaving considerable ground 

 uncultivated. 



When working on hillsides a harrow nat- lp^ The Model "B" has the most conven- 



urally has a tendency to crowd towards lent grease cups of any harrow on the 



the bottom. This is overcome Hard-on Compression Grease Cups on all market. These hard oil grease 

 by the Model "B" as you are Bearing, placed where they are easy to get at cups arc at the top of frame, out 

 able to give the lower gang a greater relative angle, of the dirt, and within easy reach of operator. 



Write us for new book, "Bigger Crops from Better Seed Beds." 

 Mailed free if you mention the Irrigation Age.

Model "B" 

 Construction 



The Model "B" 

 Disc Harrow frames 

 are built of double 

 steel bars instead 

 of single, are stiff 

 and strong with ex- 

 tra clearance. They 

 are securely riveted 

 together, and in 

 fact every part of 

 the machine that 

 has to stand any 

 strain is so well 

 braced that there 

 are no weak parts. 



Discs, Bearings and Scrapers 



Deere Disc blades are made of the highest qual- 

 ity of steel, thoroughly polished on the cutting side, 

 and ground to a sharp cutting edge. 



Bearings are hard maple and oil soaked. There 



is less friction between 

 wood and iron than 

 two pieces of iron. 

 This makes these bear- 

 ings run lighter and 

 not cut out so quick- 

 ly. They are also 

 cheaper to renew. 

 Scrapers are of the swinging type, independently 

 removab 1 e, adjustable and replaceable. Can either 

 be locked off the disc entirely when not needed, 

 permitted to hang loose, or be closely applied to the 

 discs, keeping them absolutely clean. 



STEEL STUB POLE 



is practically indestructible and enables you to 

 store harrow in a very small space. Is na- 

 turally stronger and more durable than 

 wooden stub pole.
