Abstract
Seed press wheel for sowing units for precision seeders. The seed press wheel includes a solid tire in the shape of a disc that has a hole or central axis for mounting the tire on a hub. The solid tire has a first portion extending radially from the central axis, and a second portion extending radially from the first portion, the first portion being made of a first material having a first modulus of elasticity value, and the second portion being made of a second material having a second modulus of elasticity value, the first modulus of elasticity value being different from the second modulus of elasticity value.
