122 THE POTATO 



elevator and shaker attached; No. 150, medium size 

 elevator and twenty-eight-inch wheels; No. 155, 

 large elevator, thirty-two-inch wheels, and kickers 

 for heavy conditions, as to ground, grass, vines, 

 etc. They have steel spurs on the wheels, and are 

 designed so that wearing parts can be easily and 

 cheaply replaced. They can be thrown in and 

 out of gear from the seat. The plow is adjustable 

 so as to get all of the potatoes with as little cutting 

 as possible and as Uttle soil, and so that draft will 

 not be too great. 



THE JOHN DEERE MACHINERY 



The machinery described in the following para- 

 graphs is made by Deere & Company, Moline, 111. : 



John Deere Two-Way Sulky Plow 



A fine plow for potato growers and truck farmers. 

 It turns all the soil one way, leaving no dead fur- 

 rows or back-furrow ridges. In irregular fields it 

 leaves no crooked dead furrows — and all furrows 

 are straight. When used in arid climates, harrow- 

 ing and planting can be kept up with the plowing. 

 In this way evaporation is checked and seed is 

 planted in moist soil. 



John Deere Model "B" Flexible Disk Harrow 



No tools equal a good disk for finely pulveriz- 

 ing the soil. One or two diskings make a nice, 

 deep, mellow seed bed for potatoes. 



Spring pressure enables this harrow to penetrate 

 and cultivate an even depth the full width of cut. 

 Third lever controls spring, hence operator can 

 set the disks for thorough work in all conditions. 

 Either solid or cutaway disk blades may be bad.
