ABSTRACT:
A suspension system for a row crop planter unit which includes a shock absorber extending between the planter unit mounting bracket and the parallel arm linkage which vertically mounts the planter unit to a toolbar. The shock absorber permits the planter unit to move more quickly in the rebound cycle than in the compression cycle to reduce row unit bounce.
