Due to the trapezoidal distribution of the soil loosening tools, the device is also guided and stabilized laterally better in the lane.
- the pulling device is associated with at least one further adjusting means in order to reduce part of the weight of the To transfer the soil tillage implement to the tractor.
- the weight distribution between tractor and reconsolidation unit can be varied flexibly. Since the contact pressure of the depth control device is still regulated, which is now by the further adjusting means between the tractor and
- Soil cultivation device changed weight distribution also kept constant.
- the weight transfer to the tractor by means of a traction amplifier as adjusting means which cooperates with the three-point hydraulic system of the tractor, does not adversely affect the control quality of the contact pressure of the depth control device.
- the soil cultivation device is associated with a preferably height-adjustable transport undercarriage.
- a simple road transport of the soil cultivation device is associated with a preferably height-adjustable transport undercarriage.
- Soil cultivation device allows. When arranging the chassis between the area of the soil loosening tools and the
- the transport chassis via adjusting means together in a sequential circuit with the adjusting means for
- the invention relates in particular to a harrow which is designed as a tine cultivator or disc harrow. Especially These devices have a high draft requirement with increasing working depth and require the benefits of a regulated depth control.
- Traction behavior of the pulling tractor made possible by the bearing pressure of the depth control device is limited to the ground and controlled. Also, the trouble-free use of a traction amplifier for transmitting
- Depth guide device fulfills its task in constant contact with the ground with controlled contact pressure, especially in rough terrain in an optimal manner and ensures a constant work of the
- Tillage implement without being overloaded. Thanks to the constant working depth and reduction of tractor slip, the drive energy requirement and thus fuel consumption and CO 2 emissions are reduced to a minimum.
