Universal Plow, with interval mold-board for plowing flat furrows in smooth grass 



This is furnished with a number of different mold-boards, for dif- 

 ferent purposes. It was tried only on greensward. It had a con- 

 cave mold-board, like that of Prouty & Mears', turned the sod 

 handsomely, pulverized the earth, covered the grass well, and laid 

 the furrows flat, but was rather hard to hold, from the side pressure 

 of the mold-board against the turning sod. It was afterwards fitted 

 with a small second mold-board in front, constituting it a Double 

 Michigan or sod and subsoil plow, and did excellent work. As a 

 single sod plow, it cuts a slice 7 inches by 14, and 71 by 15 ; as a 

 Double Michigan, it cut a foot wide, and ten inches deep, measuring 

 from the surface of the unplowed sod to the bottom of the furrow. 



The price, with the necessary parts to make it a Double Michigan, 

 is ^18.50; besides for this purpose, the cost of a common sward 

 mold -board is |i3.50 — stubble mold-board or for " upland sod," $3 

 — extra cutter, $1.50 — the whole $2G.50.
