摘要：
A knife assembly mountable to a frame of a seeder is provided comprising a knife shank having a proximal end and a distal end, the proximal end of the knife shank adapted to be directly or indirectly attached to the frame; a knife blade removably attached at or near the distal end of the knife shank; and a tube holder having a groove along a portion of its length, the groove designed to slidably receive a corresponding ridge on a flexible drop tube, the tube holder being attached at or near the distal end of the knife shank behind the knife blade so that both the knife blade and the flexible drop tube can be removed individually without disturbing the other elements of the knife assembly.
