FARM MACHINERY AND IMPLEMENTS 1ST 



standardize his various machines in order to know what machinery will 

 be required for his various operations. 



There are many factors influencing the duty of a given machine, 

 such as the speed of the team, the weather conditions and the condition 

 of the ground. On an average, the daily duty of a machine in acres is 

 equal to the width in feet times 1.4. In other words, a 12-inch plow will 

 average 1.4 acres per day. A 6-foot mower will cut 8.4 acres per day. The 

 size of fields will also influence the duty, since small fields require more 

 turning and loss of time. 



Careful investigations in Minnesota and Ohio show that in the 

 former state the acre cost of corn machinery is $1.07, while in the latter 

 it is only 49 cents. The lower cost in Ohio is due chiefly to the relatively 

 larger acreage of corn per farm and the fuller utilization of machinery.
