4.0 Description of the implement
This section contains general information relating to your implement, as well as information regarding:
• Characteristics of the implement
• Description of the assemblies
• Technical data
4.1 Functional description
The seed bed combination harrow serves to loosen and crumble the top ground layer and thus
prepare the seed bed before sowing. It is coupled to the tractor with the three-point linkage.
The working widths lie between 3.0 m in rigid versions and between 4.5 m and 9 m in folding
versions. In the folding versions the side frames are folded in by means of hydraulic cylinders.
The transport width of 3 m is maintained with all versions.
The basic design of the seed bed combination harrow is comprised of a main frame with a tower, tine
modules and trailing rollers.
Implement description
The 150 x 150 mm main frame ensures a sturdy and durable design.
The tine modules are individually swing-suspended.
Depending on the tine design they are equipped with 4 rows or 5 rows of tines.
The rows of tines are each equipped with either 4 or 5 tines.
The tines are distributed across the harrow eld such that there is a tine spacing (line spacing) of 94
mm (4 rows, 4 tines) or 60 mm (5 rows, 5 tines), depending on the version.
The tine rows are installed onto a parallelogram frame and adapt perfectly to the ground contours.
The working depth is adjusted via a perforated bar with pins.
The trailing rollers bear the construction during operation.
The seed bed combination harrow can be equipped with tine trails and wheel mark eradicator.
The height adjustable tine trails even out the ground without forming walls and break up large clods.
In order to side-step stones the tine trail levelling bar is suspended using springs - stone protection.
The wheel mark eradicator can be adjusted to the tractor wheel track.
With large working widths the height adjustable support wheels are tted to support the side frames.
The maximum working speed for the seed bed combination harrow is 15 km/h.

Appendix - Ballast calculation
19.0 Appendix
19.1 Ballast calculation - combination of the tractor and implement
Coupling implements to the front and rear three point linkage must not result in the total permitted
weight, axle load or tyre capacity of the tractor being exceeded.
The front axle load of the tractor must be at least 20% of the empty weight of the tractor at all times.
You should ensure that these requirements have been fullled before coupling the implement by
carrying out the following calculations.
For the calculation, data is required:
• from the operating instructions for the tractor
• from the implement's operating instructions
• from weighing and measuring
