Abstract
A disc mower-conditioner having a disc cutterbar with transversely spaced rotatable disc cutters to sever standing crop material by an impact action and a rotatable conditioning mechanism mounted rearwardly of the cutterbar to receive and condition severed crop material is disclosed wherein each disc cutter member is provided with a crop lifting ramp portion adjacent the peripheral edge of the disc cutter adjacent each knife in both leading and trailing relationships thereto. The inclined ramp portions are operable to lift previously severed crop material away from the corresponding knife before the knife severs standing crop material and to feed the severed crop material into the conditioning mechanism. The inclined ramp portions are provided on both sides of the knives to permit the disc cutter member to be rotatable in either clockwise or counterclockwise directions and still provide a leading crop lifting action. The leading inclined ramp portions can be provided with replaceable wear members to extend the operative life of the disc cutter member.
