Abstract
A rig assembly on a combination row crop cultivator and chemical applicator includes a knife or other applicator device supported in front of the cultivator sweep and behind the disk coulter blade. The sweep helps seal the chemical in the ground in certain soil conditions to prevent chemical loss, particularly when additional closing structure is not in use. A selectively attachable, shank-mounted closing mechanism, preferably a press wheel, may be mounted directly behind the sweep to assure a good chemical seal. Disk coulter support straps have flanges that provide a conveniently accessed mount for the applicator device and present minimal interference to trash and soil flow. A simple bracket connects an arm on the closing wheel mechanism to a central portion of the sweep standard. Numerous combinations of tools and tool mounting arrangements and adjustments are facilitated by the rig construction.
