SEED FIRMING ASSEMBLY FOR AGRICULTURAL SEEDERS AND MOUNTING SYSTEM THEREFOR

摘要

A seed firming assembly is mounted to a planter by a bracket attached to a seed tube guard between a pair of opener disks. The bracket has first and second sides that define a cavity therebetween for receiving a seed tube. A first mounting structure in front of the cavity secures the bracket to the seed tube guard. A second mounting structure behind the cavity attaches a seed firmer to the bracket with a pivot connection that allows rotation of the seed firmer relative to the bracket about a generally horizontal transverse axis. A stopper bushing limits an extent of forward pivoting of the seed firmer relative to the bracket, and an adjustable tensioner mechanism limits an extent of rearward pivoting. The seed firmer has an upper portion comprising a leaf spring, and a lower portion comprising a material that has a higher abrasion resistance than the upper portion.

主权项

1. A seed firming assembly for an agricultural planter, comprising:
a seed firmer for firming seeds in a furrow, said seed firmer having an upper portion and a lower portion; said upper portion comprising a flat leaf spring adapted to be attached to a bracket secured to the planter between a pair of opener disks, said upper portion being formed of a first material; said lower portion being attached to said upper portion and adapted to extend downwardly and rearwardly from said upper portion to engage a bottom of the furrow, said lower portion being formed of a second material which has a higher abrasion resistance than said first material; and said bracket has first and second sides that define a cavity therebetween for receiving a seed tube, a first mounting structure in front of said cavity for securing said bracket to the planter, and a second mounting structure behind said cavity for attaching said seed firmer to said bracket.
