Grain drills require an average repair expense of $0,027 per acre. 

 The average 6-foot drill used in this territory costs about $72, and 

 the total repairs made during its life amount to approximately 29 

 per cent of the cost when new. 



THE CORN PLANTER. 



Corn is usually planted in drills with the grain drill in western 

 New York, so that few corn planters were reported for this section. 

 The areas devoted to corn do not justify the purchase of a special 

 planter for this work, as the cost of their use per day and per acre 

 is greater than where the grain drill is employed to do the corn plant- 

 ing as well as the other seeding. From the limited data submitted 

 for corn planters (Table IX), the 1-row type averages less than 1 day 

 of use annually, while the 2-row type is used even less. 



The replacement charges for corn planters costing $12 is $1,025 

 annually, or $0.25 per acre. The interest charge is $0.46 per annum, 

 or $0,112 per acre. For planters costing $40 the corresponding 

 charges are: Replacement, $3.64 per annum, or $0,438 per acre; 

 interest, $1.13 per annum, or $0,136 per acre. 



Corn planters are comparatively expensive tools to keep in repair. 

 The average 1-horse planter costs $0.69 annually for repairs and the 

 2-horse planter $1.68 annually. The total repairs during the life of 

 the 1-horse machine amount to an average of 67 per cent of its first 

 cost, while the total for the 2-horse machine is about 46 per cent of 

 the first cost. The average cost for repairs per acre in this section 

 is $0.17 for the 1-horse planter and $0.20 for the 2-horse planter.
