Discharge Auger System
Ground feed from the mixing tank is discharged by an auger system consisting of three hydraulically
motor driven augers that are connected in series so that all augers are synchronized as well as started
and stopped together. If any motor malfunctions, the movement of material through the augers will stop
immediately. The discharge auger unloads material to any point within a 300 degree radius. The length
of the unloading auger is approximately 12 feet, without any extensions. By adding a 3' or 6' folding
extensions, the length can be increased. A transport cradle is provided for holding the unloading auger
in position during transport.

Needle Valves
An adjustable needle valve is provided on each hose of the discharge auger
rotation to control the speed of auger swing to provide smooth rotation. Needle
valves are located at the rear of the machine by the hydraulic rotation motor.
See the Adjustment Chapter of the manual for adjustment details.
Discharge Auger Door & Hydraulic On/Off Valve
An on/off valve with a pressure relief controls the hydraulic motors which
operate at a single constant speed determined by the speed of the tractor
PTO. A discharge auger shut-off door is provided to regulate the amount of
feed passing into the discharge auger.
NOTE: Always activate the hydraulic on/off valve to engage the discharge
augers before opening the discharge auger shut-off door. When the mixing
tank has been unloaded, close the discharge auger shut-off door then shut-off
the hydraulic on/off valve .
