Abstract

A center pivot mower conditioner includes an input driveline connected directly to a power transfer arrangement forming a part of the mower conditioner for providing input power to the cutterhead assembly and to the conditioning roll drive arrangement. The power transfer arrangement is in the form of a gearbox having a stationary lower section fixed to the frame of the mower conditioner, and an upper section pivotably mounted to the lower section for movement about a substantially vertical pivot axis. The driveline provides input power to the gearbox upper section, which is transferred to the lower section through a vertical pinion shaft. The vertical pinion shaft is connected to the cutterhead assembly for providing input power to the cutterhead assembly. The gearbox is preferably located toward the center of the mower conditioner, to provide input power to the cutterhead assembly substantially in the center of the cutterhead assembly. The stationary lower section of the gearbox includes a gear arrangement providing output power to a horizontal output shaft. A conditioning system drive shaft extends between the output shaft and the conditioning system drive arrangement, for providing input power to the conditioning system drive arrangement through the gearbox.
