Abstract
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).
Claims3
A planter having a seed hopper with a cylindrical wall at its lower end confronting an annular seed singulating plate rotatable about a vertical axis characterized by
- an annular wear ring of wear resistant material removably positioned at the lower end of said seed hopper and disposed in radially confronting relation to the circumferential periphery of said seed singulating plate, said ring being circumferentially split and
- means releasably connecting one circumferential end of said ring to the lower end of said hopper limiting circumferential movement of said ring relative to said lower end.
