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 self-propelled windrower includes an engine compartment containing an engine-driven fan for pulling cooling air through a screen covering a circular air inlet leading into the compartment. The fan also is coupled for creating a suction in an air duct extending diametrically across the air inlet, the duct in turn being coupled to the center of a channel-like vacuum wand mounted for sweeping the exterior of the screen and removing airborne debris collected by the screen. Provided for rotatably supporting a drive shaft for the wand is a bearing support member including a cylindrical portion having an end fixed to a mounting plate secured to the air duct, the cylindrical portion having an interior end section receiving an outer race of a roller bearing having an inner race receiving and being fixed to the wand drive shaft. An electric drive motor is located within said compartment and mounted to said air duct at a side thereof remote from said screen. The electric motor is, for example, of a type normally used for driving windshield wiper blades and includes a main body disposed at a right angle to an output shaft coupled to the wand shaft by a wedge fit formed by respective frusto-conical surfaces of the motor output shaft and the wand drive shaft. The motor output shaft projects through a hole provided in the mounting plate of the bearing support member, the hole having an axially short pilot portion to accurately position the motor output shaft relative to the wand drive shaft to minimize misalignments, and secondly to minimize the binding of the motor shaft.

Mounting for drive mechanism of heat exchanger screen cleaning wand

A mechanism for shifting reel mower cutting units to a position whereat the undersides of the cutting units are exposed for service. A knuckle joint is provided for pivoting the cutting units as the lift arms are raised to thereby shift the cutting units to service positions. A connection point is provided between a yoke and the cutting unit which is located at the upper rear quadrant of the cutting unit's side frame for generally balancing the force distributed to the ground through the front and rear rollers during forward mowing operations.
