ABSTRACT:
A grain drill has the planter disc pivot arms pivoted to a bracket. The bracket pivots are above or below a slotted bar whereby the planter discs may be adjusted longitudinally of the frame. The pivot arms may be raised or lowered by reversing the brackets.
The seeder housings are clamped along a longitudinal slot in the bottom of the seed box so the housing may be adjusted to the position of the planter disc. The seeder discs are clamped to a square shaft so they can be adjusted to the position of the housing.
