A mechanism for guiding a windrower while making an initial swath pass in a multi-pass windrow merging operation in a manner to establish the lateral spacing between an end of the header and the adjacent edge of the uncut crop so that the header encounters an optimal width of standing crop in a subsequent swath pass. The mechanism is selectively positionable between deployed (working) and stowed positions to maintain machine maneuverability when not in use. The mechanism further incorporates provisions to prevent damage to the mechanism resulting from inadvertent encounters with obstacles.

Mechanism for guiding a windrower for making an initial cut for multiple windrows

The device consists of a tapered spline coupler for a drive shaft of a pull-type forage harvester. The first drive shaft and second drive shaft each have a set of tapered splines that are inserted into a tapered, internally splined coupler. A pair of retaining rings affixed to the drive shafts draws the shafts into the coupler. A retaining bolt may be tightened to force the shafts into the coupler. A method for manufacturing the spline coupling consists of a cutting a groove in the drive shafts for a retaining ring. Tapered splines are cut onto the drive shafts. A tapered bore in the coupler is cut on a lathe by a boring bar. Splines in the coupler are created by use of a broaching tool. After the retaining rings are placed on the drive shafts, a retaining bolt tightens the assembly.

Shaft coupling with tapered splines for a pull-type forage harvester

A pull type forage harvester including a header, a cylindrical cutter head having rotating knives operatively associated with a shearbar, feed rolls for receiving crop material from the header and conveying it to the cutterhead, and a blower remotely located on the forage harvester relative to the cutterhead. The blower includes a spout for expelling cut crop material to a collecting receptacle. A transverse conveyor consisting of an auger mounted in a trough receives chopped crop material from the cutterhead and conveys it to the blower. Mounted adjacent the cutterhead is a crop processor for crushing chopped crop material received from the cutterhead. The processor comprises a pair of crushing rolls aligned with the is cutterhead axis and above the transverse conveyor. Each roll includes a shaft on which are mounted a plurality of cylindrical segments having similar outer crop engaging surfaces.
