Abstract: A mower-conditioner includes a conditioning device which is mounted for being selectively shifted transverse the direction of travel so as to be offset relative to the longitudinal centerline of the mowing device. Associated with the conditioning device is a crop guide device which may be selectively adjusted to cause a narrowed stream of conditioned crop to be deposited to opposite sides of a longitudinal centerline of the conditioning device.

Abstract: A rotary cutterbar housing is constructed of a plurality of modules mounted in side-to-side relationship with the opposite sides of each module being planar and being secured in face-to-face engagement. A spur gear train is located within the housing and includes at least one gear in each module which is meshed with a spur gear of an adjacent module so that portions of the teeth of the spur gear associated with one of the modules extends a short distance into the other module, and vice-versa. The opposite sides of the modules are parallel to each other and are inclined relative to vertical such that a module between two other modules can be unbolted from them and removed without requiring the other modules to be moved in order to provide clearance for the protruding portions of the gear teeth.

Abstract: An implement hitch is mounted to the forward end of an implement tongue for swivelling about an upright axis. The hitch includes right- and left-hand arm assemblies which each include separate inner and outer arms mounted for swinging about a horizontal transverse axis defined by a connection pin located in respective rear ends of the arms. A first embodiment of the inner and outer arms includes apertured balls universally mounted in forward ends of the arms, with the balls of each adjacent pair of inner and outer arms having a hitch pin extending therethrough which is adapted for being received in the receptacle of the hook of the corresponding side of a quick-coupler carried by the three-point hitch of a tractor. In a second embodiment, radiused apertures are provided in the forward ends of the inner and outer arms in lieu of the apertured balls.

Abstract: The forward end of a draft tongue of a towed, power take-off driven implement carries a transmission including an upper right-angle gear box rigidly fixed to the tongue and a lower right-angle gear box swivelly mounted to the tongue for rotation about a vertical yaw axis. A swivel hitch includes a frame secured to the lower right-angle gear box and to an upright extending pivot member forming part of the swivel mounting of the lower right-angle gear box. A longitudinal pivot member is swivelly mounted to the hitch frame along a roll axis. In one embodiment, a vertical clevis is fixed to a forward end of the longitudinal pivot member and is pivotally connected to a drawbar adaptor for relative rotation about a horizontal transverse pitch axis, the latter being located close to the rear end of a drawbar received in a receptacle defined by the adaptor.
