Mechanical Conditions of the Plow.

along under the beam and around the lug of the share to the 

 coulter, as seen in the engraving. As the guide wheel rotates a 

 reciprocating Avith a vertical motion is given to this vibrating rod, 

 so that as the rod advances to the front of the coulter edge it 

 pushes the stubl)le from the blade and throws it down into the 

 furrow. 



LEFT HAND PLOWS. 



In some parts of the country left hand plows are very much in 

 voo-ue. The team is generally driven with a single line. In 

 Fig. 109 we give an illustration of the mode of driving. 



J^iff. 709. 



In this case the nigh horse walks in the furrow, and the single 

 line is attached to his bridle. The off horse is guided by a 

 "jockey stick," «, from the hames ring of the nigh horse, and by 

 strap c between their heads. 



PLOWING GROUNDS WITHOUT DEAD FURROWS. 



It is sometimes very desirable to do this; we therefore give 

 the annexed method of accomplishing it, taken from the "Ameri- 

 can Agriculturalist." 



PLOWING GROUND WITHOUT DEAD FURROWS. 



Dead furrows are a nuisance, especially where hoed crops are 

 cultivated; and when land is stocked down for meadows, deep 

 dead furrows make an uneven surface for the mowers and horse- 

 rakes to work over. When a field is 

 plowed in lands beginning on the out- 

 side, turning all the furrows outward, 

 and finishing the plowing in the middle 

 of the field, there will be a dead fur- 

 row from every corner to the middle 

 dead furrow of each land, and a strip 

 of ground eio:ht or ten feet wide on J^i^ff- ^ - 



one side of every dead furrow Avill be trodden down firmly by the 

 teams when turniii«r around. Plowiuir a field without dead fur-
