Abstract
A field tile float is slidably mounted on a trash guard to prevent crop residue trash from clogging the drain inlet of field tile. The float includes a buoyant body extending around the trash guard cage and a guide frame slidably mounted on the trash guard post. When surface water in the field rises, the float is lifted to allow water to flow beneath the float into the drain pipe, while the buoyant body blocks field trash from clogging the trash guard.
