Combined Rollei' and "Vibrating Harrow.—The thorough puiveriza-* 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 combined roller and vibrating harrow, the successful work- ing of which we have had the opportunity of witnessing. The invention consists of the fi-ame, A, roller, B, which may be constructed of either iron or wood, the axle of which terminates at each end in a strong crank, C, C, of from 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, Avhich extend back- wards, and are attached to opposite corners 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 inequalities 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 desir(?d to leave the ground in a rolled condition, all that is necessaiy to do is to turn over the tOngue, F, of the roller, until it rests upon the cross pieces, G, and attach the team by a chain, to what will then be the front comer of the harrow. Or should it be desired to use.
