F) If level of grain inside bag goes too high the roller must be slowed down to allow more grain to
be removed by the sweeper and discharge augers. Grain picked up and rolled as one with the plastic
sheet is the telltale sign that should be watched out for. The roller extremes where the plastic folds
converge on the centering discs is where grain is more likely to collect. If grain is being picked up then
roller speed has to be reduced. If the roller picks up too much grain resulting in prominent and growing
bulges under the plastic, it will be necessary to stop operation, cut the bag, remove plastic sheet from
roller, and reinitiate operation.
G) If grain height reaches point “A”, where a substantial amount of grain is being unloaded with none
being picked up by the roller, then roller speed should be stabilized there . Usually point “A” is the highest
point that the grain can reach without being pulled in with the plastic folds, but the actual clearance to the
roller measured in centimeters can vary. When this plateau is reached, the roller is turning at the correct
speed.
H) This is the point of equilibrium where inflow and outflow of grain are equal. The amount of grain
that can be handled has reached its peak. Increasing discharge speed should not be attempted at this
stage since no benefit in terms of time or volume will be obtained and failure of mechanical parts is a
possibility.
I) If in doubt, first always try working slower before increasing speed in a gradual manner.
E)
Grain will start coming out of the discharge auger and simultaneously it will start building up inside
the bag to form shape “B” with a certain gradient “D”. The operator should allow a buildup of grain that
will probably take a few minutes to reach point “A”.
D) Once the bag has been hooked to the roller and the augers are moving, the operator should begin
to haul in the bag by gradually turning open the hydraulic flow control valve (with the roller control lever in
its upper position).
