FARM IMPLEMENTS. 



Combined Roller and Vibrating Harrow^. — The thorough polTeiiza- 

 tion of the soil is, and will be, an important item in the tillage of the earth. 

 The most effective method, 

 therefore, of attaining this re- 

 sult, is one of interest to every 

 individual. Our engraving on 

 this page is intended to rep- 

 resent an arrangement of a 



mbined roller and vibrating 



rrow, the successful work- 

 i-C of which we have had the 



ijjortunity of witnessing. 



ue invention consists'of the 



xvae. A, roller, B, which 

 :iiay be constructed of either 

 iron or wood, the axle of 

 which terminates at each end 

 in a strong crank, C, C, of &t)m 

 six to nine inches in diameter. 

 These cranks are keyed upon 

 the axle in opposite positions. 

 Connected to the wrist pins of 

 each crank are the connecting 

 rods, D, D, which extend back- 

 wards, and are attached to 

 opposite comers of the har- 

 row, E. The attachment of 

 the connecting rods to the 

 cranks is made with universal 

 joints, so as to allow of a free 

 and easy working of all the 

 parts, and to permit the roller 

 and harrow separately to ac- 

 commodate themselves to the 

 inequaUties of the ground. 

 The manner in which the har- 

 row is vibrated through the 

 medium of the crank in rota- 

 ting with the roller, it is not necessary further to explain. If the machine 

 is used as shown in the drawing, the last operation performed will be that 

 of harrowing, but if 't is desired to leave the ground in a rolled condition, 

 »11 that is necessary to do is to turn over the tongue, F, of the roUer, tmtil 

 it rests upon the cross pieces, G, and attach the team by a chain, to what 

 irtll then be the front comer of the harrow. Or should if be desired to tise
