Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a harvesting machine, especially a self-propelled pick-up chopper for picking up and chopping corn, wilted grass, green feed and similar harvested material, with a chopper device disposed after pick-up and feed organs. The chopper device comprises a chopper drum (1) with cutting tools (3) disposed in the circumferential direction of the chopper drum (1) at a distance from one another. In order to be able to make available a harvesting machine with an advantageous vibrational behavior and lower power requirements, the cutting tools (3) are constructed with an overlapping dimension “U” with respect to the cutting tools disposed ahead and behind in the circumferential direction.

Abstract: A self-propelled harvesting machine, especially a pick-up chopper, for picking up and chopping harvested material, such as corn, green crops, etc., with a rear axle (6), which is constructed as a steerable, rigid axle, which is supported at the machine frame (10), so that it can be swiveled about a horizontal full floating axle (9), which is parallel to the direction of travel, wherein the axle body (7) of the rear axle (6) is supported with shock absorption at the machine frame (10) so that it can move up and down relative to the machine frame (10).

Abstract: For a harvesting machine, especially a self-propelled pick-up chopper for picking up and chopping corn, wilted grass, green feed and similar harvested material, with a conditioning device (5) for the harvested material, which is disposed after a feeding device (11) and a chopping device (2) and optionally engages a conveying duct or can be removed from this, the mounting and dismantling of the conditioning device (5) is simplified owing to the fact that the conditioning device (5) is connected, on the one hand, with a duct section (3), which can be pivoted about an essentially horizontal swiveling axis and, on the other, rigidly but detachably with a rigid region (8) of the conveying duct. Preferably, the swiveling axis is disposed at the underside of the pivotable duct section (3) in such a manner, that the swiveling motion of the pivotable duct section (3) is directed downward counter to the traveling direction (14) of the harvesting machine for removing the conditioning device (5).

Abstract: A harvesting machine 1, especially a self-propelled pick-up chopper with a feeder housing 8, which can be driven, has supplying elements 9 and can be transferred from a swiveled-in operating position about an axle 11 into a swiveled-up maintenance position. In order to be able to transfer the feeder housing 8 rapidly into the swiveled-up maintenance position, the feeder housing 8 can be swung out of the way forward towards the ground in the driving direction about an essentially horizontal axle 11, which is aligned transversely to the traveling direction of the machine. The supplying elements 9 of the feeder housing 8 can be driven over a drive shaft 10, which can be swiveled regionally in the same direction with the feeder housing 8 and is constructed telescope-like regionally.

Abstract: 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.
