OPERATION 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 whether the material that is being ground is lighter or heavier than average.
Page 21
Hydraulic Pump/Motor Drive The GM 170 has a double sheave on the end of the main drive shaft which is connected by a double banded belt to the hydraulic pump. The pump is belt driven directly off the main drive shaft which is coupled by the telescoping drive to the tractor PTO shaft.
Page 22
OPERATION 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.
Page 23
OPERATION HYDRAULIC OPERATED ATTACHMENTS Swinging Intake Auger (SIA) An optional hydraulic drive Swinging Intake Auger (SIA) attachment conveys material into the mill. The intake auger can be swung in and locked against the mixer tank support brace for transporting, or swung out and locked at any point.
Page 24
The GM 170 can be fitted with numerous screens that are available with various size holes to accommodate different material and grinding requirements.
Page 25
OPERATION OVERLOAD PROTECTION Main Drive The GM 170 is furnished with a 5/16 x 1” Grade 5 shear bolt protecting the transfer auger drive shaft, transmission and mixing auger. When the shear bolt fails, the transfer auger and mixing auger will stop turning. Check the rear chain tightener for proper tension if this bolt shears.
Page 26
OPERATION BLOWER INLET & OUTLET NOTE:The collector cover must always be open while grinding. Plugging in the blower inlet or outlet can be seen by the abnormal amount of dust particles in the air around the top of the collector, and/or the visible presence of dust in the mill throat area and/or a reduced air discharge at the top of the collector.
Page 27
OPERATION MILL/BLOWER DRIVE BELT SLIPPAGE Overload protection for the mill and blower components is provided by an 8 “A” section drive belt, which connects the mill/blower driven sheave to the drive sheave. The mill and blower will gradually slow down without much reduction in tractor PTO speed if plugging develops from mill/blower drive belt slippage, and stop turning the mill/blower drive shaft if plugging or breakdown occurs in the mill or blower areas.
ADJUSTMENTS MILL/BLOWER DRIVE The combination mill/blower driven sheave is connected from the main drive sheave by an 8" “A” section banded drive belt. Adjusting bolts are provided to align the drive sheave with the driven sheave as well as to adjust the drive belt tension. Sheave Alignment To align the combination mill/blower driven sheave with the drive sheave, proceed as follows:...
Page 29
ADJUSTMENTS FRONT DRIVE CHAIN The transfer auger/transmission shaft is driven by a sprocket which is connected by the front drive chain to a sprocket on the main drive shaft. The front chain tension is self-adjusted by a spring-loaded idler and does not require adjustment. The chain should be inspected periodically for signs of wear.
Page 30
ADJUSTMENTS MILL SCREEN COVER LATCHES Over-center handle latches are used to secure the mill cover tightly closed while the mill is being operated. Lock nuts on the bolts of the latches are used to adjust latching tension. This tension should be adjusted and maintained so that some force has to be applied on the handles to lock and unlock them.
SERVICE HYDRAULIC SYSTEM Hydraulic Pump Sheave Alignment The hydraulic pump drive and driven sheaves must be maintained in correct alignment and be tightly secured at all times. Hydraulic Pump Belt Tension Overload protection for the hydraulic pump is provided by a self-adjusting spring tightener that requires no adjustment.
Page 32
SERVICE MAIN DRIVE SHAFT BEARINGS Main drive shaft bearings are greased by 2 of the remote zerks in grease bank under the step by the mill cover. For bearing replacement, follow steps 1-5 from the previous Belt Replacement section in this chapter.
Page 33
SERVICE MILL HAMMER ROTATION OR REPLACEMENT To maintain maximum grinding efficiency, the mill hammers should be rotated before wear radius measures ¼” (6 mm). Mill hammers are designed to be conveniently removed and rotated through 4 positions, before they require replacement. The hammers should be replaced when all four corners are worn to ¼”...
Page 34
SERVICE MIXING AUGER & TUBE The mixing auger should be centered inside the tube at all times. Adjustment bolts are provided on the 4 supports which hold the tube for aligning and centering it around the auger. Access to the adjustment bolts and removing the mixing auger is gained through the tank lid opening in the top of the tank.
Page 35
SERVICE TRANSMISSION The GM 170 transmission can be removed from the mixer for taking it to the dealer for internal component service. Note: Internal component repairs and replacement should only be attempted by (or under the direction of) an authorized H&S Manufacturing Dealer.

NOTE:Fill the transmission gearbox to the bottom of the inspection plug hole - Do not overfill! OILING The GM 170 utilizes an automatic oiling system to lubricate the #60 main drive chain and the double #50 transmission drive chain. Any time that the discharge auger is raised, a specified amount of oil is sent to the brushes on each of the chains.
Page 39
LUBRICATION GREASING NOTE:Grease all fittings at the intervals of operation listed, before and after storing the unit, and as otherwise listed. Use a good grade of Lithium-base grease. Wipe dirt from the fittings before greasing to prevent the dirt from being forced into the bearing or pivot. Grease should come out around the shaft on sleeve type bearings.
TROUBLESHOOTING NOTE:This Troubleshooting Chapter presents problems, causes and suggested remedies beyond the extent of loose, worn or missing parts and it was developed with the understanding that the machine is in otherwise good operating condition. MILL & MIXER DRIVE PROBLEM CAUSE REMEDY PTO Shaft vibrates excessively.
Page 42
TROUBLESHOOTING MILL PROBLEM CAUSE REMEDY Decreased or low capacity Mill not operating at the Adjust tractor throttle to proper recommended RPM speed. RPM speed. Mill loses speed as material Adjust Mill/Blower sheave enters it. alignment and/or drive belt tension. Flip/turn or replace hammers. Hammers worn Rotate or replace screen.
Page 43
TROUBLESHOOTING HYDRAULICS Note: In troubleshooting a self-contained hydraulic system, it is necessary to isolate the pump from the hydraulic motors to determine which unit is malfunctioning. A worn pump or motor will both give the same system indication. Run a pressure and flow check on the pump first to make sure that it is performing within the operating specifications, then check the motor for the correct specifications.
Page 44
TROUBLESHOOTING HYDRAULICS PROBLEM CAUSE REMEDY Tank unloads slow. Insufficient oil flow to motors. Increase tractor RPM speed. Plugged oil filter. Replace filter. Replace hydraulic pump. Hydraulic pump defective. Hydraulic motor defective. Repair or replace hydraulic motor. Oil too thin. Replace with heavier oil. Not enough oil flow to hydraulic Change oil filter, replace oil with pump.
Page 45
TROUBLESHOOTING HYDRAULICS PROBLEM CAUSE REMEDY SIA turns too slow. Excessive or wet grain. The higher the moisture content and weight of the material that is being conveyed, the more power it takes. Adjust the variable speed control valve to allow more oil to the hydraulic motor.
