<p>An end closure (34) for the cutter housing (24) of a road planer (10) in which a pair of self-opening and self-closing cover plates (48, 50) provide a protective cover over a shaft clearance opening (46) in the end wall (36) of the hosuing (24). The cover plates (48, 50), pivotally mounted on an external wall surface of the housing (24) move between a closed position at which the cover plates (48, 50) cooperatively overlay the shaft clearance opening (46), and an open position at which clearance is provided for a rotatable shaft (22) extending through the housing end wall (36), in response to moving the end wall (36) vertically with respect to the frame (12) on which the cutter (20) is rotatably mounted.</p> |
