Patent ID: 7051663

Claim:
A seeding machine comprising: a longitudinally extending tow bar; a main frame transverse to the tow bar; a wing frame is pivotally mounted to the main frame so that the wing frame can be folded forward from a transverse working configuration to a longitudinal transport configuration along the tow bar; a hopper for holding seed; a pivot arm having a first end and a second end, the first end of the pivot arm is pivotally mounted to the wing frame, the pivot arm having a working position and a transport position; a planting unit is mounted to the second end of the pivot arm, the planting unit comprises a seed meter, an auxiliary hopper and a ground engaging furrow opener, wherein when the pivot arm is in the working position the planting unit is in contact with the ground; a flexible tube extends between the hopper and the auxiliary hopper of the planting unit for directing seed from the hopper to the planting unit; when the wing frame is folded forward to the transport configuration, the pivot arm is rotated to the longitudinal transport position wherein the planting unit is pivoted to a vertical position longitudinally inward of the working position; and wherein the planting unit is attached to the pivot arm by a parallel linkage that allows the planting unit to follow the ground independent of the pivot arm when the pivot arm is in the working position.
