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 is provided with a crop lifter affixed to the peripheral portion of the disc cutter adjacent each knife in leading relationship thereto. The crop lifter has an inclined ramp extending substantially a full guadrant of the disc cutter and being 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 top of the crop lifter is positioned in substantially the same plane as the raised central portion of the disc cutter for properly lifting the severed crop material toward the conditioning mechanism and for protecting the hardware detachably fastening the knife to the disc cutter.
