4.8.3 Slide Gate Adjustment
For either auger or drag unload systems, grain passes through a discharge chute, and a portion of the grain is
directed over the outlet moisture sensor. The flow of the grain over the moisture sensor is controlled by a
metering roll, which rotates at a constant speed whenever the unload system is operating

Although it is not the primary means of controlling the flow, a slide gate is available to make small adjustments.
Typically, the slide gate will not need to be adjusted during normal operation. To adjust the slide gate position,
lift up on the sliding lock plate, push or pull the slide gate to the desired location, and then lower the sliding
lock plate, ensuring that it engages with one of the notch sets on the slide gate.
During normal operation, grain should cover the fin of the outlet moisture sensor at all times, and a steady flow
of grain should be observed through the viewing window on the side of the discharge chute. If the drying rate is
low enough that grain does not consistently keep the chute full enough to cover the moisture sensor, try pulling
the slide gate out of the chute one notch at a time until the flow is backing up sufficiently. If grain is backing up
too much in the chute, try pushing the slide gate further into the chute one notch at a time. Note that the notch
furthest out from the chute and closest to the slide gate handle is used to position the slide gate for cleanout,
and is not intended for normal operation. Refer to the figure below.
