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).
Pasture Mix*: Test Mixture = 72% Perennial Grass, 8% White Clover,
8% Cocksfoot, 8% Concord, 4% Red Clover
