OPERATION
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 and flow control
valve is provided to regulate the amount of feed passing into the discharge auger. For maximum unload
performance, do not run the hydraulic system no more than 2500 p.s.i. (see gauge) Running over 2500
p.s.i. will result in plugging the discharge auger system.

SELF-CONTAINED HYDRAULIC SYSTEM
Hydraulic System
The mixer has a self-contained hydraulic system composed of a pump,
reservoir w/oil filter, and hydraulic motor operated discharge augers.
Note: When operating at cold temperatures, allow the hydraulic oil in the self-contained system to warm
up at tractor idle speed with the PTO running prior to grinding.
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 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.
NOTE: Always activate the hydraulic on/off valve
to engage the discharge augers before opening
the discharge auger shut-off door. Adjust the flow
control and the door opening so that the proper p.s.i.
is maintained that is listed on the decal.When the
mixing tank has been unloaded, close the discharge
auger shut-off door then shut-off the hydraulic on/
off valve .
