A self-propelled harvesting machine, especially a pick-up chopper, for picking up and chopping harvested material, such as corn, green crops, etc., including a machine frame, a horizontally situated floating axle arranged parallel to a direction of travel of the machine, and a rear axle constructed as a steerable, rigid axle and supported on the machine frame so that it can be swivelled about the floating axle. The rear axle includes an axle body supported with shock absorption on the machine frame so that it can move up and down relative to the machine frame. The machine also includes a swiveling axle arranged parallel to the floating axle, a transverse swinging fork overlapping the axle body and hinged to the machine frame about the swiveling axle with the axle body being mounted on the transverse swinging fork, a spring element and a damping element. The transverse swinging fork is supported at a free end on the machine frame by the spring element and the damping element.

Self-propelled harvesting machine, especially a pick-up chopper

A harvesting machine such as a self-propelled pick-up chopper including a feeder housing having supplying elements and which can be transferred from a swiveled-in operating position about an axle into a swiveled-up maintenance position. In order to be able to transfer the feeder housing rapidly into the swiveled-up maintenance position, the feeder housing can be swung out of the way forward towards the ground in the driving direction about an essentially horizontal axle aligned transversely to the traveling direction of the machine. The supplying elements of the feeder housing can be driven over a drive shaft having a first portion which can be swiveled in the same direction with the feeder housing and a second portion different than the first portion which can be expanded and contracted telescope-like.

Harvesting machine, especially a self-propelled pick-up chopper

Harvesting machine for picking up and chopping corn, wilted grass, green feed and similar harvested material including a feeding device, a chopping device arranged after the feeding device and a conditioning device for conditioning the harvested material arranged after the chopping device. The conditioning device optionally engages a conveying duct. Mounting and dismantling of the conditioning device is simplified because it is connected on one side to a duct pivotable about an essentially horizontal swiveling axis and on the other side rigidly but detachably to a rigid duct. Preferably, the swiveling axis is situated below the pivotable duct such that the swiveling motion of the pivotable duct is directed downward against the traveling direction of the harvesting machine to thereby enable removal of the conditioning device.

An agricultural machine has a cooling fan with an intake covered by a filter centered on and rotating about an axis. A cleaning apparatus for the filter has a hood nonrotatable about the axis and engaged over only a small portion of an outer face of the filter, a rotatable brush inside the filter fixed in axial alignment with the hood and having bristles engaging through holes in the filter at the hood so that the bristles free particles stuck in the holes, and a fan connected to the hood for exhausting air therefrom along with particles freed by the bristles. The filter has an axially directed and radially extending end and an axially extending and radially directed side. The rotatable brush engages an inner face of the end of the filter and the apparatus includes a second rotatable brush separate from the first-mentioned rotatable brush and engaging an inner face of the side of the filter. The first brush is generally frustoconical and the second brush is generally cylindrical.
