Abstract
A seed firmer and bracket combination for a planter row unit. The bracket includes a forward end configured to mount to a frame member of the planter row unit. The seed firmer includes a body having an upper portion, a lower portion, and a resiliently flexible central portion. The upper portion of the seed firmer body is releasably retained between a forward surface and a back surface of the rearward end of the bracket by a rearwardly extending upper arm and lower arms that respectively engage a top edge and a bottom edge of the back surface preventing the seed firmer body from moving vertically and horizontally relative to the bracket until the upper arm is disengaged from the top edge of the back surface.
