Seed planter with equalizer assembly

An arm bracket assembly for use with an agriculture planter including a trailing arm frame, the arm bracket assembly comprising:

• an arm bracket configured to be pivotally coupleable to the trailing arm frame;
• first and second fertilizer furrow opener discs rotatably joined to the arm bracket;
• first and second furrow closer wheels rotatably joined to the arm bracket;
• and
• the arm bracket configured so that when the arm bracket is joined to the trailing arm frame, a pivoted displacement of one of the fertilizer furrow opener discs and furrow closer wheels in a first direction causes a pivoted displacement of the other fertilizer furrow opener disc and furrow closer wheel in a second direction opposite the first direction.

An agricultural planter comprising:

• an arm bracket comprising first, second, third, and fourth arms, and each of the arms joined to a middle portion of the arm bracket;
• two of the arms configured to join first and second fertilizer furrow opener discs to the arm bracket and extend from the middle portion so that the fertilizer furrow opener discs form fertilizer furrows on two sides of a seed furrow;
• and
• the other two arms configured to join first and second furrow closer wheels to the arm bracket and extend from the middle portion so that a pivoted displacement of the one of the fertilizer furrow opener discs and furrow closer wheels in a first direction causes a pivoted displacement of the other fertilizer furrow opener disc and furrow closer wheel in a second direction opposite the first direction.

An arm bracket assembly for use with an agriculture planter including a trailing arm frame defining a pivot point thereon, the arm bracket assembly comprising:

• a bracket comprising first, second, and third arms that each extend from a middle portion of the bracket;
• a furrow opening disc rotatably mounted on a mounting end of the first arm;
• a first furrow closing wheel rotatably mounted on a mounting end of the second arm;
• a second furrow closing wheel rotatably mounted on a mounting end of the third arm;
• and
• the middle portion of the bracket configured for pivotal coupling to the trailing arm frame at the pivot point.

An arm bracket assembly for use with an agriculture planter including a trailing arm frame, the arm bracket assembly comprising:

• a bracket configured to be pivotally coupleable to the trailing arm frame;
• a fertilizer furrow opener disc rotatably joined to the bracket;
• first and second rotatable furrow closer wheels rotatably joined to the bracket;
• and
• when the bracket is pivotally coupled to the trailing arm frame, a pivoted displacement of the first furrow closer wheel in a first direction causes a pivoted displacement of the second furrow color wheel and the fertilizer furrow opener disc in a second direction opposite the first direction.
