Planter with centrally mounted coulter apparatus

A planter assembly constructed to move in a transport direction, the assembly comprising:

• a carrier frame;
• support wheels mounted to the underside of the carrier frame along a single axis and defining a support dimension along the single axis;
• an implement bar having a length dimension that is greater than the support dimension and mounted to the carrier frame generally on a side opposite the transport direction such that ends of the implement bar extend laterally past the wheels, implement bar portions extending past the wheels being lateral bar segments and the implement bar portion adjacent the support dimension being a central bar segment;
• row units including central and lateral row units mounted to the central and lateral segments of the implement bar, respectively;
• a separate coulter/fertilizer unit mounted to each of the lateral row units on a side facing the transport direction;
• a coulter bar mounted to the underside of the carrier frame on a side of the support wheels opposite the implement bar;
• and
• a separate coulter/fertilizer unit corresponding to each of the central row units mounted to the coulter bar and aligned with a corresponding central row unit.

A planter assembly constructed to move in a transport direction, the assembly comprising:

• a carrier frame;
• support wheels mounted to the underside of the carrier frame along a single axis;
• row units linked to the carrier frame on a side of the support wheels opposite the transport direction;
• and
• a separate coulter/fertilizer unit corresponding to each of the row units pivotally linked to the underside of the carrier frame on a side of the support wheels opposite the row units for movement between a functional position where the coulter/fertilizer units engage the ground and a transport position where the coulter/fertilizer units are above the ground;
• and
• a hydraulic cylinder mounted to the carrier frame and linked to the coulter/fertilizer units for moving the coulter/fertilizer units between the functional and transport positions.
