ABSTRACT:
An agricultural planter in which three coulters are mounted on a single shaft, which shaft is supported at each end with side supports carried by the frame of the planter. A main large diameter coulter is used to break the soil to make a furrow, another coulter of smaller diameter is used to place fertilizer in one band and yet another coulter of yet smaller diameter is used to plant seed in another band with all three coulters being mounted on a single shaft. The structure described herein makes it possible to mount all three coulters on a single shaft, and yet permit each coulter to rotate independently of one another while operating as a unit.
