Abstract
A seed firming wheel assembly is supported in close-coupled relationship with the rear portion of the paired discs of an opener to gently press deposited seeds down into the bottom of a V-shaped trench formed by the discs. The mounting arm of the assembly is configured in a manner to minimize the accumulation of mud and trash residue, while the wheel itself may take the form of a solid, circular block of ultra-high-molecular-weight polyethylene with slick sides to reduce soil adherence or a spoked, molded plastic wheel having open spaces between the spokes to permit soil pass-through.
