Both the upper and lower portions are provided with aligned seed passages which received metered seed from the seed tube and discharge the metered seed to the planting furrow. The upper cast portion is mounted to the planting unit frame and the seed tube by an integral mounting clevis. The lower cast portion is provided with first and second upward extending mounting lugs. The first mounting lug is received in a recess formed in the upper portion. The second mounting lug engages the planting furrow side of the upper portion. The rear of the upper and lower portions are provided with aligned mounting holes through which a mounting bolt passes securing the lower portion to the upper portion.

Claims

1. A seed boot for a seeding machine, the seed boot comprising:

a cast upper portion adapted to be coupled to a seed tube for receiving metered seed therefrom, the upper portion having an upper seed passage, the upper portion also having an upper furrow opener side and an upper planting furrow side, wherein the upper planting furrow side has an upper side surface that is in contact with a planting furrow formed by a furrow opener for keeping the planting furrow open;

a cast lower portion that is coupled to the upper portion for receiving metered seed therefrom, the lower portion having a lower seed passage which is aligned with the upper seed passage for receiving metered seed from the upper seed passage, the lower portion having a lower furrow opener side and a lower planting furrow side, the lower planting furrow side has a lower side surface that is in contact with the planting furrow formed by the furrow opener for keeping the planting furrow open, the cast upper portion and the cast lower portion are provided with aligned mounting holes through which a mounting bolt passes coupling the lower portion to the upper portion, the upper portion is provided with an upper leading edge that extends downwardly and rearwardly and the lower portion is provided with a lower leading edge that extends downwardly and rearwardly and is in line with the upper leading edge, the upper furrow opener side of the upper portion is provided with an upwardly and forwardly extending mounting recess for receiving a first mounting lug extending upwardly and forwardly from the lower portion, the lower portion is provided with a second mounting lug extending upwardly therefrom and engaging the upper planting furrow side of the upper portion, the lower portion is provided with a recess which adjoins the upper portion for receiving a seed retaining tongue that extends rearwardly and downwardly behind the lower seed passage, the seed retaining tongue being trapped between the upper and lower portions.

2. A seed boot as defined by claim 1 wherein the upper portion is provided with an upwardly extending clevis for receiving a seed tube, the clevis is also provided with a strap and a pin for securing the upper portion to the seed tube.
