<p>A system for cleaning a grain dryer screen includes a grain dryer screen supported within a grain bin and having a grain contacting surface opposing a grain debris contacting surface. A drying airflow path through the grain dryer screen is defined sequentially by the grain debris contacting surface and the grain contacting surface. A cleaning assembly includes a first cleaning arm mounted within the grain bin and disposed along the grain debris contacting surface. A cleaning assembly powering system is configured to move the first cleaning arm along a predetermined cleaning path relative to the grain debris contacting surface.</p> |
