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 gram 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.
