A windrower platform is constructed with a full-length, upper center-feed auger which counter rotates relative to and cooperates with lower, right- and left-hand cantilever-mounted augers to convey harvested crop to form a windrow on the ground at a central discharge zone of the platform. The various driven elements of the platform are driven from a main power distribution gear box having an input shaft coupled for being driven by a reversible hydraulic fluid motor. The upper auger is used for transmitting power to the opposite side of the platform from the main power distribution gear box and a transmission assembly is provided at this opposite side for driving the lower right-hand auger in a direction opposite to that of the upper auger.

A harvester platform is suspended from the implement main frame by a linkage including a pair of lower transversely spaced links each having rear and front ends respectively pivotally attached to the main frame and the platform. Associated with each lower suspension link is a hydraulic float cylinder coupled between the main frame and the associated link so as to exert a lifting force on the link. The amount of lifting force exerted by each float cylinder may be varied by adjusting the location of the anchor pin connecting the cylinder to the main frame through means of an adjustable bracket that carries the anchor pin. Side-to-side float balance of the platform is achieved through properly adjusting the anchor pin locations so that the float cylinder at the heavier end of the platform exerts a greater lifting force than the float cylinder at the lighter end of the platform.

A self-propelled windrower is provided with a platform including a reel which sweeps crop to be cut over a sickle cutterbar and into the nip of a pair of counter-rotating center-feed augers that, in turn, deliver the crop to the nip of a pair of counter-rotating conditioner rolls; and these driven components may be reversed to disgorge slugs of crop. The reversible drive includes a hydraulic pump carried by the traction unit and coupled to a motor carried by the platform. The hydraulic motor on the platform is coupled to power a main gear box which distributes power to the driven components of the platform. Operation of the pump is electro-hydraulically controlled with a single switch being operable to effect forward operation of the platform drive train, and with a second switch being designed to be moved and held in place to effect and maintain the drive train in reverse. Both switches cannot be operated at the same time, however the machine can be reversed with the platform lowered, fully raised, or anywhere in between.

A sickle-type mower includes a cutter bar assembly having a pair of sickles mounted for reciprocable motion along respective cutter bars. The sickles include inner knife sections located to cut against stub guards mounted at inner locations of the cutter bars, with the inner knife section of the upper sickle being disposed to cut against a finger of a double hold-down located centrally along the cutter bar assembly with its fingers disposed above respective stub guards located on opposite side of the centerline of the bar assembly.
