Excluding secondhand implements, the cost per acre-time for 

 1-horse cultivators ranges from 2.6 to 6.8 cents, with the greater 

 number between 4 and 5 cents. A few 3-liorse (double row) culti- 

 vators are included with the 2 horse. Only 3 of the 2 or 3 horse 

 cultivators cost over 13 cents per acre-time. One of these was an 

 extra cultivator, 

 bought secondhand 

 and used on only 15 

 acres m four years. 

 The cost of use for 

 most of them ranged 

 between 1 and 10 

 cents per acre-tune, 

 35 out of 102 being 

 between 2 and 4 cents, 



24 between 4 and 6 

 cents, and 12 below 

 2 cents. 



The acre cost of 

 corn bhiders varies 

 greatly, but on about 

 half the farms where 

 used it was between 



25 and 45 cents per 

 acre. Two sled har- 

 vesters cost less than 

 10 cents per acre. 

 The corn shockers re- 

 ported were used on 

 a much lower acreage 

 than the corn binders, 

 with a much higher 

 acre cost. The wide 

 variation in size and

 cutters makes the 

 average of doubtful 

 value. Two cutters 

 cut about 120 tons 

 each per year at costs

 at a cost of 2.9 cents per ton. Three 2-hole corn shellers had a 

 mean cost of S2.01 per year, while seven out of eight 1-hole shellers
