87. The sulky or wheel plow. The development of thejsulky 



or wheel plow has taken place only recently. F. S. Davenport 

 invented the first successful sulky plow, i. e., one permitting the__ 



operator to ride. February 9, 1864. A rolling coulter and a three- 



horse evener were added to this by Robert Newton, of Jersey- 

 ville, Illinois. But E. Goldswait had patented a fore carriage 

 v/in 1851 and M. Furley a sulky plow with one base December 9, 

 1 1856. Much credit for the early development of the sulky plow 

 due to Gilpin Moore, receiving a patent January 19, 1875, and 

 W. L. Cassady, to whom a patent was granted May 27" 1876. 

 Cassady first used a wheel for a landside. Too much space 

 would be required to mention the many inventions and improve- 

 ments which have been added to the sulky plow.

88. The modern steel walking plow. Fig. 34 shows 

 the modern steel walking plow suitable for the prairie 

 soils. The parts are numbered in the illustration as 

 follows : 



1. Cutting edge or share. The point is the part of the 

 share which penetrates the ground, and the heel or wing 

 is the outside corner. A share welded to the landside is 

 a bar share, while one that is independent is a slip share. 



2. Moldboard : The part by which the furrow is turned. 

 The shin is the lower forward corner. 



3. Landside : The part receiving the side pressure pro- 

 duced when the furrow is turned. A plate of steel covers
