Abstract

A single arm row cleaner unit mountable to a grain drill opener arm includes a row cleaner arm and a mounting saddle. The mounting saddle is generally configured for attachment to a main arm of a furrow forming assembly. A row cleaner arm may be pivotally attached to the mounting saddle about a mandrel, and a row cleaner wheel may be pivotally mounted to the row cleaner arm. A biasing member may be positioned adjacent the mandrel to engage the row cleaner arm and a biasing member retainer, which may be affixed to the mounting saddle. A deflector may be positioned adjacent the row cleaner wheel and biased there against. A connector and lever arm may be used to communicate forces from a closing wheel arm to the row cleaner wheel for adequate clearance of the row cleaner wheel during transport of the grain drill.
