Does anybody know of a sample implementation? I am currently trying to adapt it to my country but the LADM is rather abstract. Anybody have any idea how to go about this?

You can accomplish this in ArcGIS using the following approach:
- Select the polygon/s of interest.
- Create Fishnet using the input polygons as the extent. Here, I specified 1 row and 20 columns (fishnet output is in red). You have a lot of control in this tool to determine the exact spacing you want between lines. Make sure to increase the extent of the fishnet so that it covers your input polygon when rotated.
- Use the editor tool bar (Figure 2) to rotate the fishnet. Make sure an editing session is active and you have selected the fishnet for the rotate tool to work. Note, that if you select the rotate button and then press "A", you can specify the exact angle you want.
- Use Clip to clip the fishnet to the input polygon's geometry.
This is not quite possible with the information you have provided.
The main thing missing is how to locate the "point of beginning", from which the text you provide locates the remaining points, which lie in a hexagon that is nearly a rectangle approx 350x100m+- lying roughly to that "point of beginning's" northwest.
As an example, the first line says point 2 lies 375.93 metres in the direction S 85deg 48 W, which is a bearing 4.5 degrees to the south of directly due west. For more on interpreting these instructions, see https://www.e-education.psu.edu/geog160/node/1926
Actually, to do this completely right, you would have to understand details about what grid the bearings are relative to -- see https://www.flatironsinc.com/services/learn/bearings.php -- but this is likely immaterial in your situation.
If you could pinpoint the "point of beginning", for instance by its latitude and longitude, then you could use a GIS program like QGIS, or even manual/spreadsheet calculations if you're not scared of trigonometry, to convert those bearings and distances to create a KML file that you could then display on Google Maps (or alternately show Google Maps or another map source in that same GIS program).
If you can pinpoint one of the other boundary points, you can also reverse engineer the hexagon from that other starting point. But unless you have Longitude/Latitude or other (e.g. UTM,...) coordinates for at least one of those points, you don't have enough to go by.

I would suggest to visit the LADM Wiki:
http://wiki.tudelft.nl/bin/view/Research/ISO19152/WebHome
Here you will find the complete LADM documentation, and the UML model.
Another suggestion is to go to:
http://flossola.org/
Here you will find open source software and a lot of documentation (data dictionnary included).
Further developments can be followed at www.fig.net and www.gltn.net
