The present invention includes coating composition having magnetic properties for application to a substrate. The coating composition includes a plurality of strontium and or barium hexaferrite particles having a random magnetic pole alignment. The coating composition also includes a binder adhesive capable of suspending the strontium hexaferrite particles. The binder adhesive is a natural rubber capable of adhering in a substantially thin film to the substrate. The strontium hexaferrite particles are normally present between 50% to 98% of the coating composition's total weight when dried on the substrate. The thickness of the film of the coating composition ranges from 0.5 mils to 20 mils, and has 6 to 24 magnetic pole changes per linear inch. The binder adhesive allows for manipulation of the strontium hexaferrite particles to a non-random magnetic pole alignment after the ferromagnetic particles have dried in the binder adhesive on the substrate.

Coating composition having magnetic properties

An agricultural planter having a seed singulating plate (28) rotatable about a vertical axis (30) to disperse seeds stored in a gravity flow hopper (12). A replaceable wear ring (38) of wear resistant material increases the useful life of the hopper and permits the renewal of a high wear surface without replacement of the hopper lower portion (14).

Planter hopper with wear ring

A rotating disc has perforated seed pockets which pick up individual kernels of seed from a cavity of a planter housing. Bulk seed flows by gravity from a hopper to the cavity which is pressurized by a blower. As the disc rotates through the cavity, air flowing through the perforated pockets will move the seeds into the pockets and hold them there as the disc rotates to bring the seed carrying pockets into axially confronting relation with a flat sealing surface. The flat sealing surface holds the seed in the pockets as the disc rotates further to a position wherein the pockets are exposed to an open bottom area of the housing at which point the seeds are free to fall by gravity into the soil.
