DESCRIPTION:

BRIEF SUMMARY
The invention relates to an equipment system for agricultural ground soil preparation having a frame unit which, by means of a lifting rod assembly or three-point rod assembly, can be vertically adjustably coupled to a traction vehicle, such as a tractor, and is used for ground soil preparation equipment which can be combined in different ways, such as a power take-off shaft driven rotary device with dovetailing prongs or similar devices which produce a similar stream of soil which, behind the rotary device with dovetailing prongs, is guided to the ground by means of devices arranged there, and a sowing machine which has vertically adjustable seed delivery pipes which can be mounted behind the rotary device with dovetailing prongs or the like and project into the stream of soil thrown up by the rotary device with dovetailing prongs or the like, and a land roller or clod breaker apparatus and plow accessories or the like, which vertically adjustably can be mounted at the frame of the rotary device with dovetailing prongs in front of the rotor. At the frame of the rotary device with dovetailing prongs or the like, a trestle-type frame part is fixedly arranged which can be coupled to the lifting rod assembly three-point rod assembly. The land roller or clod breaker apparatus has a separate frame which, in the manner of a rocker device, pivotably adjustably around a transverse axis, can be connected to separate connecting points of the frame of the rotary device with dovetailing prongs or the like.
In principle, combination machines are known for agricultural ground soil preparation which, during a single passage over the ground to be worked or tilled, carry out several operations simultaneously.
EP-A 02 01 785, for example, describes an agricultural combination machine of the initially mentioned type.
The sowing machine of this known machine may selectively be equipped with sowing plows which operate behind the clod breaker apparatus, or with seed delivery pipes which operate within the stream of soil thrown up by the rotary device with dovetailing prongs in front of the clod breaker roller. In order to prevent in this case that the spaces between the seed delivery pipes are clogged by adhering soil or plant residues, the seed delivery pipes are arranged directly in front of the clod breaker roller, specifically in such a manner that rows of teeth arranged on the clod breaker roller project into the spaces between the seed delivery pipes. In this manner, the spaces are kept free of cloggings by means of the teeth of the clod breaker roller which move while the machine is driving. However, for this purpose, clod breaker rollers are required which have correspondingly long teeth; i.e., any arbitrary type of clod breaker rollers cannot be used.
In EP-A 02 01 785, the sowing plows are arranged in two rows behind one another, in which case, sowing plows which follow one another in transverse direction of the machine are alternately assigned to one or the other row. Such an arrangement is necessary in order to be able to achieve a relatively narrow line distance in transverse direction of the machine by means of sowing plows.
Since the sowing plows cut into the soil, they basically have the disadvantage that plant residues remaining in the soil may adhere to the sowing plows. Therefore, sowing plows are disadvantageous in cases where fairly large quantities of plant residues remain on or in the ground.
In the case of the combination machine shown in EP-A 02 01 785, the clod breaker roller also has the task of guiding to the ground the stream of soil thrown backward by the rotary device with dovetailing prongs.
Another combination machine is shown in EP-A 02 11 967.
In this case, a premounted apparatus, which carries plow accessories and is supported on the ground to be worked by means of its own wheels, can be coupled to a traction vehicle by means of a three-point rod assembly.
A second apparatus, which is constructed as a circular spike harrow can vertically movably be connected to the premounted apparatus by mea
