PATENT CYLINDER PLOW, 



WITH SKIM, OR SUBSOIL ATTACHMENT. 



This Plow derives- its name from the form of the mold-bonrd, 

 which is a segment of a perfect cylinder, with its ends cut in the style 

 of ordinary mold-boards. Its lines are thus always horizontal to 

 the surface of the land, and consequently it turns the furrow-slice 

 with the same uniformity as a wheel on its axle, and with the least 

 possible friction. The friction is still further reduced by the peculiar 

 arrangement of the share and land side, which, combined with its 

 other improvements, reduces the draught from one-fourth to one-third 

 less than that required by the best class of Plows now in general use. 



For lightness of draught, simplicity of construction, ease of hold- 

 ing, and certainty of turning all soils of any required depth and 

 width, it far surpasses any other Plow. 



All the sizes are capable of turning either flat or lap furrows, of 

 any required lap, by using shares suited to various widths, all of 

 which can be supplied ; and every furrow may be left concave on the 

 under, and convex on the upper side, which gives the lightest and 

 most friable condition to the soil, admitting of easy and thorough 

 pulverization by a light harrow or cultivator. 



This front plow can be raised or lowered to turn any required depth 

 of upper furrow, or it can be removed entirely, at the pleasure of the 

 operator. 



We have 137 distinct sizes and varieties of Plows on our Price 

 List, and most of the larger ones are arranged with fin or wrought 

 cutters, wheels and draft rods, as may be desired. They are cast iron, 

 polished and half polished, steel, wroughtiron, &c., embracing every- 

 thing required for sward and fallow plowing, elevating, deep 

 trenching, subsoiling, <!fcc. *
