    摘要： A harvesting apparatus includes a crop conditioning element coupled to a frame, and a hood moveable relative to the crop conditioning element. An actuating system moveably connects the hood to the frame. The actuating system includes a driven lever arm rotatably attached to the frame and including a first lever connection and a second lever connection positioned opposite each other across a lever rotation axis. A first pivot assembly is rotatably attached to the frame and includes a first pivot connection coupled to the first lever connection of the driven lever arm, and a second pivot connection coupled to a first lift connection of the hood. A second pivot assembly is rotatably attached to the frame and includes a third pivot connection coupled to the second lever connection of the driven lever arm, and a fourth pivot connection coupled to a second lift connection of the hood.

    摘要： 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. Once the biasing lever is adjusted to bias the transport latch into the lock position, the raising of the header into the transport position will actuate the transport latch and lock the lift mechanism from returning the header to the lowered position. The lift linkage incorporates a cam mechanism that serves as an upper flotation limit under normal operating conditions and automatically converts into a device for securing the header in the transport position when the header is moved into the transport position.

    摘要： A disc mower conditioner utilizing a modular disc cutterbar to sever standing crop material by impact action supports the cutterbar from the header of the mower conditioner by a pair of transversely spaced support arms mounted by spherical bushings to the header to allow flexing of the support arms as induced by the cutterbar. The mounting of the spherical bushings utilize conical washers engagable with conical sockets in spacers to limit vertical movement of the spacer relative to the header when the corresponding support arm flexes. The mower conditioner header further includes an optional viney crop guide that has a curved leading edge that directs viney crop downwardly into engagement with the adjacent disc cutter. The viney crop guide is also bent inwardly to contain and control the flow of crop material. The mower conditioner swathboard includes a position control mechanism that incorporates a positive down stop in the form of a pin riding within a corresponding slotted opening in an associated bracket to prevent the swathboard from coming into an inadvertent engagement with the conditioning rolls.

    摘要： A conditioning unit adapted for mounting beneath the main frame of a windrower having a front mounted header pivotally connected thereto by a lift mechanism including a pair of laterally spaced lower lift arms. The conditioning unit is pivotally mounted about the rear thereof to the main frame of the windrower and includes a pair of rollers rotatively mounted about front outside portions, the rollers being laterally spaced and adapted to rest upon the lower left arms such that the conditioning unit moves proportionally to the movement of the header.
