The tongue is bent in the horizontal plane and incorporates a generally vertical box section at the end of the tongue. The tongue supports a driveline transmitting rotational power from a prime mover to the operative components of the mower-conditioner. The driveline incorporates a clutch assembly mounted on the input shaft of a bevel gearbox. The forward end of the input shaft is formed with a conical surface that mates with a corresponding conical hub bore formed within the clutch assembly. The end of the input shaft is formed as a truncated cone to provide a gap between the end of the shaft and the bottom of the bore and assure a proper seating of the two members.Type: GrantFiled: February 8, 1999Date of Patent: February 15, 2000Assignee: New Holland North America, Inc.Inventors: Kenneth W.

Patent number: 5996323Abstract: A modular disc cutterbar utilizes self-contained cutter modules clamped between alternating spacer modules by fasteners engaged with the spacer modules. To resist bending moments in the cutterbar, selected fasteners can have a length to span more than one cutter module. The drive mechanism is also of a modular construction including a symmetrical, reversible sealed drive apparatus within each cutter module and a transfer shaft passing through each interstitial spacer module to interconnect each cutter module drive mechanism. The drive apparatus incorporates an oil slinger to keep the remote seals lubricated. The rock guard for each cutter module is mounted on the adjacent spacer modules, while the skid shoe mounting is simplified. A crop mover mounted on each disc member above the cutting knife improves the transfer of severed crop material.Type: GrantFiled: April 15, 1998Date of Patent: December 7, 1999Assignee: New Holland North America, Inc.Inventors: Steven J.

Patent number: 5953893Abstract: A disc mower incorporates a modular disc cutterbar surrounded by a flexible canopy supported from a frame. A split guard is mounted to the distal end of the mower canopy to keep objects away from the end of the disc cutterbar. The guard presents a smooth contiguous surface to prevent debris and crop material from catching the guard. The guard has an L-shape configuration, including a front member leg oriented to project rearwardly while a rear leg member is oriented to project forwardly. The front and rear legs overlap in line with the transverse pivot axis of said canopy support such that the split guard presents a continuous edge for effectively deflecting crop material.Type: GrantFiled: April 15, 1998Date of Patent: September 21, 1999Assignee: New Holland North America, Inc.Inventors: Barry E. Smith, Darryl T. Leeds, Steven J. Campbell

Patent number: 5916112Abstract: A guide link mechanism is supported from the draft tongue of a pull-type harvester and connected to the gearbox mounted on the crop harvesting header to provide rotational power thereto wherein the guide link is supported from a sliding mechanism mounted on the tongue that accommodates the changes in distance in respective points associated with the pivotal movement of the draft tongue about a different pivot center than the gearbox. The sliding mechanism includes a bracket affixed to the underside of the draft tongue and low friction inserts, such as nylon, phenolic, urethane or polyethylene inserts, carried by the bracket. The guide link is connected to a slider plate that is slidably received by the phenolic inserts to permit a sliding movement thereof relative to the draft tongue. The rearward end of the guide link is pivotally connected to the gearbox to accommodate vertical movements of the crop harvesting header relative to the draft tongue.Type: GrantFiled: February 5, 1998Date of Patent: June 29, 1999Assignee: New Holland North America, Inc.Inventors: Thomas L.

Patent number: 5778647Abstract: 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.Type: GrantFiled: June 25, 1996Date of Patent: July 14, 1998Assignee: New Holland North America, Inc.Inventors: Kenneth W.
