At this point in time it is convenient to set the approximate speed at which the roller will work. The roller works in the same manner as a winch,
pulling in emptied bag plastic and providing advance movement to the tractor/unloader combo.
Now back up the unloader into the bag to the point where the sweep augers come lightly in contact with the grain, but do not attempt to wedge
the augers forcefully into the mass of grain. On doing this maneuver, it is important to check that the machine's wheels do not tread on the
plastic. The plastic must stay inside the wheels.
Turn the roller until the line of studs are in the uppermost position (Fig. 33)
Having already described how the hydraulic commands drive the roller and with the tractor hydraulics operating, it is convenient to begin with
the control knob turned completely clockwise (zero movement) and then gradually turn it clockwise to increase rpm's. Draw a visible mark on
the outer disc of the roller to time the roller's rotational speed. To achieve maximum output, the roller should take between 30 and 40 seconds to
complete one revolution, so set it initially within this range. Fine tuning will be done once operation is underway. Speed is directly proportional to
hydraulic flow provided by tractor, which should be a minimum of 60 liters/minute.
