PNEG-1079 6", 8" and 10" Vertical Bin Unload Auger
To Start Auger
1. Before starting the tractor, be certain power to PTO is OFF.
2. Start tractor.
3. Engage PTO at a slow RPM to minimize shock loads. Then work up RPM to recommended speed.
To Stop Auger
1. Let auger empty of grain before stopping.
2. Disengage PTO and lock out.
Electric Motor Drive
Use a 1750 RPM motor with HP as suggested in the
Electric motors and controls shall be
installed by a qualified electrician and must meet the standards set by the National Electrical Code and all
local and state codes. Use a 4-1/2" motor pulley (not furnished) for 650 RPM flight speed (6" and 8").
Use a 4" motor pulley for 580 RPM flight speed (10").
A magnetic starter should be used to protect the motor when starting and stopping. It should stop the motor
in case of power interruption, conductor fault, low voltage, circuit interruption or motor overload. Then the
motor must be restarted manually. Some motors have built-in thermal overload protection. If this type
motor is used, use only one with manual reset.
The horsepower recommendations are based on clean, dry shelled corn or wheat. High moisture grain
(above 15%) will require greater power. The maximum possible capacity will be less with high moisture
grain than with dry grain.
Horizontal Flight and Horsepower Required
Never operate the auger empty for any length of time as excessive wear will result. If at all possible, do
not stop or start the auger under load, especially before the flight and tube become well polished, as this
may cause the auger to “freeze-up”. (See break-in information
)

NOTE: For higher moisture grain (up to 25%) the next larger motor may be used as a maximum.
Reset and motor starting controls must be located so that the operator has full
view of the entire operation. A main power disconnect switch capable of being
locked only in the OFF position shall be provided. This shall be locked
whenever servicing or adjusting the auger.
DANGER
Disconnect power before resetting motor overloads. Make certain electric motor
is grounded.
