ABSTRACT:
The invention provides a packer wheel to be towed behind agricultural equipment such as an air seeder, the wheel being used to pack the soil in which seed or fertilizer has been placed. The packer wheel includes a hub and a body extending from the hub to a peripheral wall. A plurality of circumferentially spaced slots extend from the peripheral wall inwardly of the wheel body. Adjacent slots define therebetween a fin which, due to the slots, is somewhat flexible. As the packer wheel rotates the fins will flex sightly, but enough to cause any mud, soil or debris that built up thereon to break away so that the packer wheel remains relatively clean, even in muddy conditions. The slots are shaped so that any mud or debris that builds up therein is automatically forced axially outwardly of the slots as the wheel rotates.
