Implements with side screening plates

摘要

A harrow has an elongated frame beam supporting a row of rotatable soil-working members mounted side-by-side on upwardly extending shafts. The frame beam and row of soil-working members extend transverse to the direction of travel of the harrow. At each lateral end of the row, a screening plate is positioned and pivoted to the frame beam. Each screening plate extends in a substantially vertical plane in the general direction of travel. Also, each plate has a lower support portion that rides over the ground and side edges that are inclined upwardly. The screening plates are supported on arms that can be pivoted to relocate the plates 180 degrees so they can rest in inverted positions on top of the frame beam during transport.
