Embodiment Construction

[0022] figure 1 A towed semi-mounted soil tillage device 1 is shown, here a short disc harrow. Likewise, other equipment designs such as, for example, toothed cultivators, driven rotary harrows, toothed or milling rotors are included. The soil tillage device is coupled via a tow hook 11 to a lower link of a tractor, not shown, as a traction motor. The lower links are the tractor's three-point power lift, with these the equipment can be raised out in the front area. The coupling to the lower link is achieved by a sliding shaft that pivots axially in the direction of travel, the lateral movement of which is limited by rubber buffers when the entire device is tilted. On the rear side, the towing hook 11 is rotatably or pivotally mounted via a rotating vertical axis. Likewise, the hitch 11 can be designed as a three-point tower for coupling to the upper and lower linkages of the tractor's three-point hydraulic system and then fixed to the tie rod 14 either by a cardan shaft or ...

Abstract

The present application proposes a soil tillage device (1) having a rake or leveling device (4) mounted on its front, wherein when the tool strength of the rake or leveling device (4) is adjusted, At the same time, the distance in the direction of travel between the tool supports or between the tool supports and the dragged soil tillage device (3) is varied in a simple manner.

Description

technical field [0001] The invention relates to a soil tillage device with a rake or leveling device according to the preamble of patent claim 1 . Background technique [0002] Straw rakes or pulling implements are known to disperse crop residues after harvest in a field, in particular straw left behind, and to facilitate subsequent tillage of the soil, as well as to improve the incorporation of crop residues into the soil. German patent application DE102008059144 A1 proposes such a straw comb. For example, the combination of different implements such as comb harrow and rear disc harrow is advantageous for dispersing and mixing work in one pass in the field. For example, European patent specification EP 1529430 B1 describes such combinations. Due to the length of the device, the height in its retracted state exceeds the vertical height permitted in road traffic. In order to limit the overall vertical height of the entire device, the first row of teeth of the rake can be f...
