Abstract
A scraper blade for a row unit of a planter. The scraper blade has a connecting portion that connects to the pivot hub of a depth-gauge assembly. The connecting portion connects to a blade portion. The blade portion is positioned in a gap formed between the pivot hub and the contact surface of the depth-gauge wheel. The scraper blade is connected to the depth-gauge assembly in a static and stationary position at a pivot point. As a pivot arm and the depth-gauge wheel move about in relation to the pivot point, the scraper blade maintains a fixed position at close tolerances with the depth-gauge wheel to remove soil and debris from the depth-gauge wheel.
