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.-lbs. (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,
install the drain plug in the back plate of the transfer auger. Make sure that the drain plug below the
supplement hopper in the transfer auger is also installed. If the mixer is equipped with a Swinging 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

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, reinstall the plugs.After a rain, check the mill, mixing tank, and augers for
water accumulation before operating the mixer. 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.

TRACTOR CONNECTIONS
PTO
Fasten the Grinder-Mixer to the tractor drawbar with a hitch pin with safety locking device, and attach the
Grinder-Mixer PTO to the tractor PTO shaft locking it into position.
1. Maintain a straight alignment between the grinder-mixer and the tractor.
2. Maintain a 15-1/2” distance between the lock on the tractor PTO and hole on grinder-mixer hitch
for a 540 RPM machine.
3. Maintain a 17” distance between the lock on the tractor PTO and hole on grinder-mixer hitch for a
1000 RPM machine.
4. Maintain a distance of 6”- 12” between the top of the tractor drawbar and the center of the tractor
PTO. An 8” distance is standard.
PREPARING FOR OPERATION
PREPARING MIXER
* Properly lubricate the grinder-mixer, checking the transmission and cyclonic reservoir oil levels, and
filling if necessary before operating the grinder-mixer.
* All drain plugs must be properly installed and secured.
* Follow the procedures outlined in the Operation Chapter of this manual for installing the mill screen.
* The tank lid and the discharge auger door must be closed and the cyclone cover must be open.
* Start the tractor, engage the PTO at idle speed and increase the rpm’s until the grinder-mixer is running
at the rated PTO speed. Begin the grinding process.

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,
3.) The tank lid is closed,
4.) 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 models of electronicscalesareavailableforaccurate 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: When transporting the mixerandmixing, disengage the tractorPTObefore turning corners
to prevent damage to the PTO driveline.

OPERATION
540/1000 RPM PTO DRIVE
The H&S GM 170 grinder-mixer features a 540 drive as standard
equipment for use with tractors up to 115 hp (86 kW).
Anoptional 1000 RPM driveis available foruse with tractors upto
145 hp (109 kW).
MILL & BLOWER
Drive Sheave
Themill/blowercan be engaged ordisengagedbythe positioning

and rotate it onto the L-shaped bracket.
IMPORTANT: When starting the Grinder-Mixer, engage the
tractorPTOataslowidlespeed.Advance the throttleofthetractor
to the rated PTO speed.
-18-
CAPACITY
The GM 170 mixing tank capacity is 170 cubic feet or 135
bushels by volume. The tank will hold approximately 6000
lbs of ground feed consisting of average weight corn, small
grain and/or concentrates. More or less weight (per tank) is
possible,depending upon whetherthe material thatis being
ground is lighter or heavier than average. Grinding capacity
of the mill will vary due to the type of material being ground,
the moisture content of the material, the size screen used,
andthe horsepower ofthe tractor usedto operate themixer.
The mixer is designated for operation by a 50 to 115 hp (28
to 86 kW) 540 RPM tractor or by a 50 to 145 hp (38 to 109
kW) 1000 RPM tractor.
Mill & Blower Operation
Material enters the cylinder chamber through the mill inlet and is
drawn into the cylinder by a vacuum below the cylinder. The
vacuum below the cylinder is obtained by the physical location of
the blower Inlet below the cylinder.
The21”cylinderis composed of sixty-six swinging hammers which
are equally divided among three rows around the cylinder.As the
cylinder rotates at the recommended speed of 2700 RPM, the
hammersgrind the materialand force itthrough the screen.Once
throughthescreen,thegroundmaterialdropsdown to the transfer
auger and is conveyed to the mixing tank. Lightweight chaff or
dust is drawn into the blower inlet and forced by the blower up
intothecollectorwhereitisrefinedandseparated.Heavy particles
are directed back down into the transfer auger and conveyed to
the mixing tank.
