H, High = 19t on Clutch Output Shaft,
15t on Gearbox Input Shaft.
L, Low = 15t on Clutch Output Shaft,
19t on Gearbox Input Shaft.
For Grain, changing the Shutter Slide from 3/4 to Full gives
10% to 15% more flow.

Bottom Flap*: The values shown were the optimum test settings,
decreasing the gap may cause seed damage, too large a gap will give
intermittent flow rates. (Flaps are spring loaded to cope with small
variations in seed/granule size).
