to equalize the draft between the leaders and the two horses 

 directly behind them, a short, vertical evener of metal or a 

 chain and pulley may be used. In the case of the five-horse 

 evener, the end hole for the single horse hitch should be 

 four times as far from the center hole of the evener as the end 

 hole for the four horses working in pairs. In case of the six- 

 horse evener, the hitch for the team should be twice as far 

 from the center hole as the 

 hole for the four-horse 

 hitch. 



Plain Eveners. Simple 

 or plain eveners are much 

 to be desired. There is 

 absolutely nothing to be 

 gained by a complicated

system of levers and tog- 

 gle joints. If there is to 

 be an equalization of the 

 draft, there should be a 

 flexible hitch; and if the 

 evener is attached to the 

 plow or other implement 

 at more than one point, the hitch cannot be truly flexible. 



Overcoming Side Draft. With four horses hitched 

 abreast, on a sulky plow the line of draft lies outside of the 

 line of resistance, and there is a tendency to throw the front 

 end of the plow away from the land. This tendency can be 

 partly overcome by adjusting the front furrow wheel in such 

 a manner as to pull the plow toward the unplowed land, as 

 previously discussed. (See page 203.) 



The tongue truck is the only satisfactory means of off- 

 setting draft, and for this purpose it is a commendable device. 

 The truck should be provided with heavy flanged wheels
