85' 



made to dip so that it shall enter the ground easily. The only force it requires is 

 the landside pressure, which would be entirely lost in producing friction and resist- 

 ance. Consequently the employment of this cutter utilizes that force, and enables 

 the same team to turn a furrow one-third wider than they could turn without it. 

 Moreover, a plow fitted with the landside cutter, moves more steadily than one not 

 so provided, therefore is more easily guided by the plowman, who is thus enabled 

 to do more work with less labor. The cutter is veiy easily adjusted to any plow, 

 or removed from it, so that this vast improvement can be applied by any one at a 

 cost of about $'2. 



Figure 1. 



Fig. 1 represents a cast steel prairie 

 plow, made by John Deere, Moline, 



any part of the west. It cuts 12 inches 

 wide without, and from 15 to 16 inches 

 wide with the landside cutter. 



Fig. 2 represents a fine German steel 

 plow, made by B. Martin & Co., of 

 Cleveland, Ohio. It is adapted to all 

 kinds of work in that locality. Mr 

 Martin's testimony, as to the utility 

 of the landside cutter, is as follows : 



" The capacity of the plow is a fur- 

 row slice twelve inches wide, by eight 

 inches deep; perfect work with a draft 

 of 375 lbs., first trying the plow with- 

 out the landside cutter. We then 

 attached your improvement. The se- 

 cond time around I changed the line of 

 draft to enable the plow to take a 

 Avider furrow. It then carried an 

 18-inch furrow, actual measurement, 

 without any perceptible increase of 

 draft.
