Abstract: The apparatus is a rotatable bale forming roller for use in farm machines that form round crop bales. The roller is a cylinder with multiple ribs oriented parallel to the roller axis and formed in the roller surface. The roller is constructed with a frame of channel shaped members oriented parallel to the roller axis with the channel members interlocking with several discs oriented perpendicular to the roller axis. A thin high strength steel sheet is installed completely around the frame to form the surface of the roller, and the integral ribs are formed directly in the sheet. In the preferred embodiment, the ribs have leading surfaces oriented in planes that are radial to the axis of the roller, and the trailing surfaces of the ribs are oriented to form an acute angle with the leading surfaces.

Abstract: A pull-type mower conditioner includes a crop harvesting header vertically movable relative to the frame of the mower conditioner between a raised transport position and a lowered operative position, a lift mechanism to effect the movement of the crop harvesting header relative to the frame, and a transport latch mechanism to control the locking of the lift mechanism in the transport position. The transport latch mechanism has a biasing lever operably positionable between locking and unlocking positions. An extension spring is connected to the biasing lever to bias the lever in the selectable positions. The transport latch will not engage whenever the header is moved to the transport position to avoid an obstacle unless the biasing lever is moved to the lock position.
