OPERATION (cont.) CAPACITY The GM 170 mixing tank capacity is 170 cubic feet or 135 bushels by volume. The tank will hold approximately 6000 to 7000 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 22
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 23
OPERATION (cont.) 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 24
OPERATION (cont.) 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 26
OPERATION (cont.) 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.
Page 27
OPERATION (cont.) 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 28
OPERATION (cont.) 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...
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 driven sheave, proceed as follows: 1.
Page 30
ADJUSTMENTS (cont.) 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.
Page 31
ADJUSTMENTS (cont.) 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.
LUBRICATION GENERAL INFORMATION IMPORTANT: The GM 170 must be properly lubricated, the transmission and cyclonic oil reservoir must be filled to the proper oil levels before it can be operated. IMPORTANT: Catch and dispose of fluid per local waste disposal regulations whenever service is performed on hydraulic components (valves, cylinders, hoses, etc.) or transmission.
