2.2.2 Overview of Operator’s Controls
Operator controls include:
•
Hopper tilt cylinder:
The hopper tilt cylinder uses the tractor’s second hydraulic circuit to raise and
lower the hopper platform. Operation of the hopper tilt cylinder is performed using the controls for the
tractor’s second hydraulic circuit which are located on the tractor. Figure 2.1 shows the hopper platform
in the operating position with the hopper platform lowered to the frame.
•
Tractor engine speed:
The tractor engine speed should be set so 1000 PTO shaft is running at 1000
RPM.
•
Tractor PTO lever:
Engaging the tractor’s PTO lever spins the rotor runs the conveyor belt and belly
auger. The conveyor must be unfolded to working position before the PTO is engaged.
•
Conveyor hydraulic controls:
The front lever controls the up/down of the conveyor and the next lever
controls the fold/unfold of the conveyor. One tractor hydraulic circuit is required to power the hydraulic
controls.
•
Auger hydraulic control:
The hydraulic control on the auger engages and disengages the auger.
2.2.3 Rotor
The rotor and screens are the heart of the grain processor. The rotor on this GP-50 Grain Processor is equipped with
132 swinging hammers. Dull edges on the hammers and/or screens will result in a loss of capacity and increased
horsepower requirements
Important:
Hammer and hammer rod life can be extended by keeping the rotor rotating at 2500
RPM.
Excessive tractor horsepower and/or overfeeding the rotor can cause the hammers to lay
back resulting in excessive wear on both hammers and hammer rods.
CAUTION:
Keep all foreign objects out of the hopper and away from the rotor. Foreign objects
may cause personal injury or damage to the Gp-50 Grain Processor.
CAUTION:
At full speed, energy is stored in the rotor.
Do not use the tractor PTO brake to stop
the rotor. Reduce engine speed before disengaging the PTO.
2.2.4 Screens
All GP-50 Grain Processors require two screens. They come equipped from the factory with a 2” diameter hole screen
and a 3” diameter hole screen. Any combination of hole sizes may be used. As a general rule, use the largest diameter
screens capable of doing the job.
When using a combination, place the smallest hole diameter on the right hand side of the rotor box where the material
enters the rotor.
The size of the hole in the screen determines the coarseness of the grind. The larger the hole diameter, coarse the grind.
Hole sizes can vary form 1/8” diameter through 8” diameter.
