A towed agricultural machine for tillage purposes and/or for sowing seeds is disclosed. The machine comprises a running gear, tillage tools, and a packer unit, the latter being coupled to the running gear and forming a constructional and/or functional unit therewith. In a first operating position, the running gear is in an active position for road traffic and the packer tools are brought outside the engagement range with the ground. In a second operating position, the running gear, or at least parts thereof, are in an inactive position out of contact range with the ground, while the packer tools are in an active mode in engagement with the ground.
A towed agricultural machine for tilling and/or for sowing seeds, the machine comprising a machine frame and tillage tools arranged thereon, and further comprising a packer unit arranged subsequent to the tillage tools in the driving direction of the machine and hinged pivotally and height adjustably on the machine frame, which packer unit is assigned a running gear comprising at least two rear support wheels, which are arranged in the area of the rear end of the machine, the machine being characterized in that the packer unit, which is pivotally and height adjustably journaled on the machine frame, comprises a module with a running gear and/or rear support wheels as well as packer tools arranged thereon, which module is journaled to be pivotal in relation to the packer unit between two stop positions, wherein either the running gear or the packer tools face toward the ground and/or are in engagement or in contact with the ground in the respective stop positions, and wherein the packer unit and the module journaled thereon are each assigned separate adjustment devices, which are controllable independently from each other and which are employed for adjusting and/or pivoting the packer unit and the module arranged thereon.
A method for the conversion and/or functional change of a towed agricultural machine, the conversion and/or functional change being effected between a first operating mode for tilling and/or for sowing seeds and a second operating mode for road traffic, wherein the machine comprises a machine frame and tillage tools arranged thereon and further a packer unit arranged subsequent to the tillage tools in the driving direction of the machine, the packer unit being hinged pivotally and height adjustably on the machine frame and the packer unit being assigned a running gear comprising at least two rear support wheels, which are arranged in the area of the rear end of the machine, characterized in that the packer unit is pivotally and height adjustably journaled on the machine frame and comprises a module with a running gear and/or rear support wheels as well as packer tools arranged thereon, which module is journaled to be pivotal between two stop positions, wherein either the running gear or the packer tools face toward the ground and/or are in engagement or in contact with the ground in the respective stop positions, and wherein the packer unit together with the module journaled thereon are height adjustable and/or pivotal in relation to the machine frame by means of a first adjustment device, and wherein the module is switchable between its two stop positions for driving on the road and for driving on the field by means of at least one second adjustment device.
