Hydraulics
TheGM170 requires a4 hosehook-up; 2hoses forthe dischargeauger lift,and 2hoses forthe discharge
auger rotation.

WHEELS & TIRES
The Grinder-Mixer is shipped without the rims and tires installed on the axle hubs. Install the rims and
tires, and torque the wheel nuts to 90 ft-lb (124 N-m). Inflate the 12.5L x 15 - 20 ply tires to 80 PSI (563
kpa).
DRAIN PLUGS & DRAIN COVER
When the Grinder-Mixer is delivered, the drain plug on the back plate of the transfer auger will be in the
storage position. See the diagram below for the storage position. When the GM 170 is ready for delivery,
installthedrain plug intheback plate ofthetransfer auger. If themixer is equippedwith aSwinging Intake
Auger (SIA), the drain plug will also be in the storage position. Upon delivery, also install the drain plug in
the drain hole in the bottom of the SIA attachment.
IMPORTANT: Never open or plug the water drain holes with the mixer running.
SET-UP & ASSEMBLY
-16-
STORAGE
IMPORTANT: If the GM 170 is stored outside, the water drain holes must be left unplugged. Before the
mixer is going to be operated, re-install the plugs. Before operating the mixer after a rain, check the
several vulnerable areas for water accumulation. As necessary, drain the water before using the mixer.
NOTE: After water has been drained from the mixer, it is advisable to run the GM 170 while empty for a
period of time in an attempt to dry the mixer before grinding to eliminate any sticking of material and
possible plugging.

OPERATION
EMERGENCY SHUTDOWN
In an emergency or in case a foreign object enters the mill
inlet, stop mixer operation immediately by disengaging the
tractor PTO.
GENERAL INFORMATION
Check entire unit carefully before first operation. Tighten bolts and set screws that might have come
loose in shipping. Lubricate as explained in the Lubrication Chapter in this manual.
NOTE:These procedures must be done before grinding;
1.) Grinder mill door is closed.
2.) The collector cover is open,
2.)The tank lid is closed,
3.) The unloading auger shut-off door is closed.
Operate the mixer on level ground for uniformity of mix. Maintain a straight-line alignment between the
tractor and mixer to prolong the life of the drive line components.
Maintain the tractor rated PTO speed which produces a mill cylinder speed of 2700 RPM, to obtain the
most efficient grind. Do not exceed a cylinder speed of 3000 RPM. Before grinding, the unloading auger
shut-off door must be closed.
Add supplements after a small amount of feed has been ground, then dry granular materials.
NOTE:Do not grind feed with high moisture content. This may cause plugging.Abnormally damp crops
will not feed or mix well.
Grinding should be stopped when the feed in the windows begins to drop.
IMPORTANT: Overfilling the mixing tank will place unnecessary stress on the drive line components.
Keep the tank lid closed and properly latched so that if the tank is accidentally overfilled, the lid can pop
open and release the feed inside the tank.
The two full-length windows on the tank are calibrated with numbers representing bushels of ground
feed.
NOTE:Optional modelsofelectronicscalesareavailablefor accurate weight measurements and rations.
Stop the tractor and disengage the mill/blower drive sheave pin after grinding. Start the tractor and allow
the mixer to continue running for several minutes to thoroughly mix the ground feed.Allow the mixer to
continue running during transport, disengaging the PTO on corners or turns.
IMPORTANT: Whentransporting themixer andmixing, disengagethe tractorPTObeforeturning corners
to prevent damage to the PTO driveline.
