A. Knowing the bin size and the length of flighting to be used in the unloading tube is necessary to
determine how much horsepower is required for the job.
B. Use the Chart below to determine the size of motor required. Use a larger motor when encountering
high moisture or when high capacity is required.
NOTE: For high capacity or high moisture, use one size larger motor.
LONGER BELT NOTE: Longer belts may be required when using larger framed motors due to high
capacity or high moisture applications.
C. The following horsepower recommendations are for augering relatively dry grain. Use an electric
motor of the proper size that operates at 1750 RPM. Motor pulleys are not furnished with the auger.
D. A magnetic starter should be used for the operator’s protection and for the protection of the motor.
This helps to protect the operator against accidental re-start caused by power interruption, conductor
fault, low voltage, circuit interruption or motor overload. Therefore, the motor must be restarted
manually. If using a motor with built-in thermal overload protection, make sure this type of motor has
a manual reset.

WARNING
Electrical controls and wiring should be installed by a qualified electrician. The
motor disconnect switches and conductor cables should comply with the
National Electrical Code and any local codes which apply. Reset and motor
starting stations should be located so that the operator can see that all personnel
are clear of the equipment.
WARNING
Disconnect and lock out power before resetting motor overloads. Make certain
electric motors are grounded.
