Glencoe 7400 soil saver chisel plow

[vicsec]

Lost our manual for this machine. Can anyone explain which direction the teeth be attached? It has 9 shanks and I assume some of the teeth should throw one direction and some the other. Looking at it from the back of the machine, which ones go which direction? Thanks.

These photos might be some help. Each point throws in the opposite direction.
