ABSTRACT:
A tractor drawn and powered impeller mower-conditioner includes a transverse disk type cutter bar. An impeller rotor with free swinging flails is mounted above and slightly to the rear of the cutter bar with its axis of rotation parallel to the cutter bar. A transversely extending concave conditioning plate conforms closely to the forward upper quadrant of the rotor. A hood covers the rotor and conditioning plate and includes a forward portion which serves in part as safety shielding and a rearwardly extending crop deflecting and windrow forming portion. The rotor is disposed and rotated so that the flails intercept cut material delivered rearwardly by the cutter bar and carry it inside the hood up and over the rotor through the confined space or conditioning zone between the rotor flails and the conditioning plate and discharge it rearwardly. In its passage through the conditioning zone, the crop material is bruised or conditioned in such a way that its rate of drying in the window is accelerated. The conditioning plate is mounted so that radial clearance between it and the rotor flails can be adjusted to vary the degree of conditioning. Circumferential adjustment of the plate in relation to the rotor is also possible and particularly useful in setting the height above the ground of the leading or lower edge of the conditioning plate to suit the height of the crop being cut and conditioned.
