Seed boot having a wear resistant insert
摘要:
A seed boot for use with a furrow forming disk of a grain drill for depositing seed within a furrow. The seed boot includes a housing having an inner side, an outer side and a furrow firming edge. The furrow firming edge extends between a lower edge of the inner side and a lower edge of the outer side. The furrow firming edge includes an opening positioned below an axis of the disk and in communication with an internal seed delivery tube that extends the length of the housing. At least one side wear insert is attached to the lower edge of the outer side of the seed boot to prevent side and down force wear of the seed boot.
